Q1. What is a Decision Support System (DSS)? How many types of DSS are there?

Ans. DSS is a computer-based tool that helps project managers analyze data, evaluate alternatives, and make informed decisions to optimize project performance. It integrates data from various sources, applies analytical models, and provides interactive dashboards to support planning, scheduling, risk assessment, and resource allocation.

Key Functions of DSS in Project Management:

1. Project Planning & Scheduling – Helps in creating and optimizing project timelines (e.g., Critical Path Method, PERT).
2. Resource Allocation – Assists in assigning manpower, budget, and materials efficiently.
3. Risk Management – Identifies and mitigates risks using predictive models.
4. Cost-Benefit Analysis – Evaluates financial feasibility and ROI of projects.
5. Performance Monitoring – Tracks KPIs and provides real-time insights.
6. Scenario Analysis – Simulates “what-if” situations to assess project outcomes.

Types of DSS in Project Management

Project management DSS can be categorized into five main types, each serving different decision-making needs:

1. Data-Driven DSS-Uses historical and real-time project data for analysis. Dashboards (e.g., Power BI, Tableau for project tracking) and Business Intelligence (BI) tools for trend analysis.

2. Model-Driven DSS-Applies mathematical models for optimization and forecasting. Critical Path Method (CPM) & PERT analysis for scheduling. Monte Carlo simulations for risk assessment. Earned Value Management (EVM) for cost and schedule performance.

3. Knowledge-Driven DSS-Uses AI, expert systems, and rule-based reasoning for decision-making. AI-based project risk predictors (IBM Watson for risk analysis). Chatbots & virtual assistants for project guidance.

4. Communication-Driven & Group DSS (GDSS)-Supports collaborative decision-making in project teams. Microsoft Project Online and Teams.

5. Hybrid DSS-Combines multiple DSS types (data + AI models). Integrated Project Management Software (Primavera, JIRA with AI insights).ERP systems with DSS modules ( SAP for project analytics).

Q2. What is a Fishbone diagram and when to use it?

Ans. Fishbone Diagram or Ishikawa Diagram or Cause-and-Effect Diagram is a visualization tool to understand the potential causes of a problem to identify its root causes. It resembles a fish skeleton, with the problem at the “head” and possible causes branching out like “bones.” 

It is best used in:

1. Root Cause Analysis (RCA) – To systematically explore why a problem occurred.
2. Problem-Solving Sessions – Brainstorming possible causes in teams.
3. Quality Control – Identifying defects in manufacturing or service processes.
4. Process Improvement – Mapping factors affecting efficiency (e.g., delays, errors).
5. Risk Management – Anticipating potential failure points in projects.

Q3. What is RAID in project management and why is it necessary to create a RAID log?

Ans. RAID is an acronym for Risk, Assumptions, Issues, and Dependencies. It is a structured approach to tracking key factors that can impact a project’s success. It helps project managers proactively manage uncertainties and obstacles. 

A RAID log (typically a spreadsheet or tool like Jira, Excel, SharePoint) is essential because it:

Improves Risk Management- Identifies threats/opportunities early, allowing mitigation strategies.

Clarifies Assumptions-Documents uncertain factors, reducing surprises. 

Tracks Issues Proactively-Ensures problems are assigned, prioritized, and resolved (avoiding last-minute firefighting).

Manages Dependencies-Prevents bottlenecks by highlighting critical links between tasks/teams.

Enhances Communication-Serves as a single source of truth for stakeholders (e.g., in steering meetings).

Supports Decision-Making-Provides data to reallocate resources, adjust timelines, or revise scope.

Q4. What is CMM?

Ans. The Capability Maturity Model (CMM) is a framework developed by the Software Engineering Institute (SEI) at Carnegie Mellon University to assess and improve an organization’s software development processes. 

5 Levels of CMM Maturity- Initial – Start point of a new process.

Repeatable– It suggests the repeated use of any process.

Defined – It includes documentation of the standard guidelines and procedures.

Managed – It involves the measurement and management of a process.

Optimizing – It is the highest level of process maturity in CMM and includes optimization and improvement of a process.

Level	Name	Key Characteristics
1. Initial	Chaotic/Ad-hoc	Processes are unpredictable, poorly controlled, and reactive. Success depends on individual heroics.
2. Repeatable	Basic Project Mgmt.	Processes are documented for tracking cost, schedule, and functionality. Some discipline exists (e.g., version control).
3. Defined	Standardized	Processes are standardized across the organization (e.g., using SOPs, training). Focus on consistency.
4. Managed	Quantitatively Managed	Processes are measured and controlled using data (e.g., statistical process control). Predictable outcomes.
5. Optimizing	Continuous Improvement	Processes are refined via feedback, innovation, and defect prevention (e.g., automation, root-cause analysis).

Q5. How do you handle any changes to the project?

Ans. A PM needs to have a high level of adaptability. Nobody wants changes in a project but sometimes they are not under the control of PM and due to certain unavoidable circumstances and factors, changes do creep in the project and he should be able to manage it. Handling changes in a project effectively requires a structured change management process to avoid scope creep, delays, and budget overruns. The following steps could be followed:

Establish a Change Control Process by establishing Change Request Form and Change Control Board.Assess impact of the change on project timeline, milestones, cost and quality. Update Project Plan, Scope, Risk Register and Version Control. I will assign ownership and track progress.

Q6. What values/qualities do you think a PM should have?

Ans. The role of a PM is to create an environment and atmosphere in the Programme /Project so that everybody who comes to work is motivated to deliver his or her best. Create empowerment and enablement. Some of the qualities of PM are People Management, time management, cost & conflict management and stakeholder expectations management. The PM should inspire teams, lead by example and balances authority with empathy. He should be a good listener and be able to convey clear and concise messaging. He should learn from failures and be attentive to details. He should be loyal and trustworthy.

Q7. What performance metrics do you use to determine if a project is going as expected?

Ans. The ability to understand if a project is going in the right direction is a core skill of a PM and performance metrics will help in that matter. Some of the useful performance metrics are Quality, Customer Satisfaction, and Gross Margin, Planned vs. Actual Timeline, Cost Variance, Defect Density and Test Coverage, Story points completed per sprint and Resource Utilisation, Net Promoter Score (NPS) and Change Request Volume, Team Productivity and Stakeholder Feedback.

Q8. What strategy do you follow to mitigate the risks involved in a project?

Ans. There will always be risks involved in a project; sometimes even before one starts it. We need to understand the Requirement and the associated risks involved with it in details from the business & technology and then plan and proceed with it. Risks cannot be eliminated but can be mitigated only. We can adopt the following strategy:

Risk Identification- Proactively identify potential risks before they escalate. Brainstorming, SWOT Analysis.

Risk Assessment (Qualitative & Quantitative)-Prioritize risks based on impact and likelihood. Monte Carlo Simulation, Decision Tree Analysis.

Risk Response Planning-Develop actionable strategies for each risk.

Risk Ownership & Monitoring-Ensure accountability and track risks dynamically. Use RAID Log.

Contingency Planning-Prepare for unavoidable risks. Create Fall Back plans.

Communication & Culture-Foster risk-awareness across the team. Use Dashboards, Agile training.

Q9. Did you ever face any challenges while managing projects? How did you handle those challenges?

Ans. I worked as Lead BA Cum PM in many projects with Citibank & CS. I faced several challenges while working there. Some of the challenges faced by me were time management, resource allocation and Delivery on time.

I started prioritizing Projects and concentrated on the highest rated projects first. I used to try and get the required number of resources with the right skill sets before starting the project and explaining the details to all the stakeholders and trying to manage the expectations throughout the lifecycle of the project.

Q10. Which of the methodologies have you used in your projects? Why do you prefer it over others?

Ans. I have used Waterfall & Agile methodologies, Earlier, Waterfall was used earlier. Later on Agile is being used while in some banks, both are being used. 

Waterfall Methodology can be used when requirements are well defined and stable, fixed and clear outcomes are known and Clients want a fixed budget or timeline. Agile Methodology can be used when requirements are evolving, frequent feedback is required and high complexity and innovation is involved. 

Q11. What do you know about the critical path of a project? What steps will you take if you find that one of your tasks is going to take more time than expected?

Ans. The Critical Path is the longest sequence of dependent tasks that determines the shortest possible project duration. Any delay in these tasks directly impacts the project’s finish date. Put simply; the critical path of a project is all the key tasks that are required to complete a project. There are ways to shorten task time. E.g. adding an extra person to the project on the contract or from a different team to complete the particular tasks. Run parallel tasks (if dependencies allow). Try Scope reduction, if possible and use Overtime, weekend work for the team.

Q12. Do you prefer working on a single project or multiple projects at the same time?

Ans. I believe I can be more efficient if I work on a single project. But if required, I am willing to take up multiple projects occasionally. It all depends on the situation. I would prefer single-project if it involves critical, complex or innovative work. However, I may opt for multi-project in dynamic, resource-constrained environments but limit to 2–3 projects at a time in order to avoid burnout.

Q13. Which one skill does a project manager need to succeed?

Ans. In order to succeed, a PM needs multiple skills and it is really difficult to pinpoint a single skill required for success. Probably, Team building skills are often the most essential skills for the PM as he can only lead the team in the right direction if they are cohesive and well organized. However, the PM must be equally versed in leadership and communication skills, decision making, time management, and resource allocation. All these skills are essential for his success as a project manager.

Q14. How will you handle the failure of a project?

Ans. Being a PM, one should be able to handle both successes and failures. While informing about the failure of a project, one should always ensure that it doesn’t impact the morale of the team and the work pace. I would like to adopt the following strategies:

Immediate Damage Control– A software launch fails QA. I will roll back the release and notify users of delays. I will undertake a Root Cause Analysis (RCA). I will focus on Stakeholder Recovery Plan. Try to rebuild trust & momentum avoiding blame game and focussing on people and systems.

Q15. What was the most difficult decision you have made?

Ans. I had to remove one knowledgeable developer from the Project due to his stubborn attitude as he was not ready to contribute in any other area despite requesting him several times. He was a Java guy. We wanted a Talend guy desperately & he used to know Talend. But he kept on refusing to work on Talend for reasons best known to him only. The Management even offered to compensate him. He even started inciting other members of the Team. It started having an effect on all other team members and since the Project had a very tough deadline, it led to both time and cost overrun and ultimately led to delayed release. I was left with no option but to remove him from the Project. This happened in Citibank Project in 2010 in London.

Q16. How are you managing projects while working from home?

Ans. I have been working from home for the last 3 years. For better project management, I used to follow several things while working from home. Set and prioritize things as per the requirements. Focus on clear and timely communications. Set remote working guidelines so that we meet the desired expectations and maintain productivity. Extensively use project collaboration tools to increase the productivity and conduct daily & weekly meetings for discussing project updates and problems.

Q17. What do you do when you/your team does not meet the project’s deadline or budget?

Ans. Sometimes despite the best efforts or intentions, the project is unable to meet the deadline or exceed the budget due to several reasons. The delay can be due to unclear requirements and deadlines, poor monitoring and tracking, performance issues, inefficient process and unavailability of required resources or technical issues. I would like to find and understand the root cause for the delay or escalation and then go to the stakeholders, explain everything and take their approval for the new deadline or the new budget as the case may be.

Q18. How do you handle an unhappy client?

Ans. As a PM, it is my job to keep the stakeholders satisfied. However, there are times when the business is not happy with the project deliverables. In such cases, some of these practices help: 

Communicating with stakeholders at regular intervals, listening to their problems before reacting, looking for a work around between the needs, Evaluating and discussing their expectations and Asking questions and giving the desired solutions or work arounds.

Q19. What is your approach towards gold plating?

Ans. Gold plating in project management is about delivering more than what was desired. From the client’s point, this is a good thing and can make them happy. However, this can severely affect the project’s predefined timelines and can also add to the costs. Thus as a PM, it is our  job to control gold plating which can be done in several ways:

Define and assign clear KPIs to project team members

Connect with leaders to monitor if any team member is doing gold plating

Give a clear message to the members involved in the same by first making them understand what is gold plating and how s/he is doing it along with pros and cons. The objective should not be to demotivate the person involved but to make his/her understand the desired scope of work.

Make a note of possible ideas of optimization possible in the project and give the same to the sales team who can convince clients for further optimizations resulting in up-selling.

Q20. End Users rejects the final deliverables. What will you do?

Ans. First of all, I would like to understand the reasons for rejection. I would then start having a conversation with the end users, and initially, I will bring up the scope of the project and ask on what ground they are rejecting the project when my team has met all their initial requirements. Before starting this in the actual conversation, I will ensure that I have not missed anything from my end.

Also, in such situations, I will ask the end users about any additional expectations, discuss and plan with the internal team, share the additional costs with them and post-approval, deliver the final product.

Q21. Your team has some internal issues and the project is suffering due to these internal conflicts. What will be your course of action?

Ans. Internal conflicts are quite common in project management as we are dealing with multiple people across different time zones and different locations. As a PM, I would like to identify:

The root cause of the conflict and its impact on the project and what can be done to motivate people in order to bring back the project on line.

If the issues are still persistent, then I would like to search for alternative solutions. Certain issues which need to be taken care of are: Individual targeting, displaying empathy, resolving problems analytically and giving reasonable solutions.

Q22. What is your leadership style?

Ans. I believe in Team building and working with empathy. I do not believe in any fixed leadership style. Rather given a chance, I would prefer Leading by Example, Leading through communication, Delegation and Accountability. I will explain what needs to be done and give clear understanding to the team. I will facilitate easy and quick communication within the team. I will also delegate the jobs based on an individual’s strengths and areas of interest. Avoid micromanagement and keep everyone on the same page and ensure that my team clearly understands my expectations. I would like to set milestones and celebrate even small success & achievements. I also like “Give and take feedbacks” style.

Q23. Do you believe in delegating responsibilities/work?

Ans. Every project has a pre-defined goal that needs to be delivered by a given time. Thus, most often project managers need to delegate the job to their team members with complete responsibility.

That makes this question among the most important ones as through this question, the hiring manager is trying to understand your ability to lead, flexibility, and team management skills.

Share your experience of how you used delegation as a strategy to get the work done and deliver the project on time.

Q24. How do you manage to drive the team towards achieving the desired goals and project expectations?

Ans. As the leader of the team, it is the responsibility of a project manager to deliver the project on time. For this, it is very important to stay self-motivated and at the same time, ensure that the team members are also motivated. One can follow the following steps:

• Set realistic goals/deadlines and clearly state them to the team
• Plan and execute based on project timelines
• Anticipate the possible disasters and plan a way out beforehand
• Offer a room to team members to share their ideas, feedback, and views
• Conduct frequent project review meetings to discuss the progress and talk about the challenges faced by the team to give timely resolution
• Set milestones and celebrate small success/achievements
• Give and take feedbacks
• Incentivize if possible
• Provide access to the right project management tools and technologies

Q25. Why do you think you are goal-driven?

Ans. Being goal-driven makes one impactful at work and that’s why you need to prove that you are a goal-driven person who has the ability to drive the project as per the planned strategy.

When the recruiter shoots this question during your project management interview round, you need to answer them aptly by describing past incidents that prove that how you:

• Break long projects into sprints
• Plan your time effectively
• Write everything down
• Organize your work
• Motivate your team
• Delegate the job
• Offer/ask for constructive feedback

Also state how you have delivered the projects in the past, what strategies you have used, etc. as this will convenience the interviewees that you are goal-driven.

Q26. How do you inspire the team member who is not very motivated and ensure that he/she delivers the desired results?

Ans. Every team has a set of employees who are somewhat demotivated, underperforming, sensitive, or/and restraining. However, as a project leader/manager it is the job to handle all such employees and direct them in a path where they start performing. I would like to do the following steps:

Observe if this is a one-time thing or happens frequently and try to have a conversation with the person and let them open up so that you offer help.

Set a KPI dashboard to track project performance.

Keep everyone on the same page and ensure that your team clearly understands your expectations.

Value the team’s feedback and suggestions.

Avoid micromanaging.

Help the team to learn and grow.

Q27. How do you manage your team’s workload?

Ans. Managing workload is another important aspect of a PM’s job. This needs to be well planned to keep moving forward the project in the right direction. The below steps help:

Review the team’s current workload by following the matrix organizational structure.

Use resource management reports to find ways for answering project related queries

Connect with team members who are overloaded and find ways to optimize their tasks.

Delegate responsibilities to staff who have less on their plate.

Plan upskilling and training sessions for employees.

Q28. Describe the steps of a project from initiation to completion.

Ans: The various stages of a project are initiation, planning, execution, monitoring and control and closing. As a PM, it is my responsibility to see that my team handles each of these stages efficiently while staying within budget and completing it on time.

Initiation Phase involves defining the project’s purpose, feasibility and stakeholders. Planning Phase involves creating a roadmap for execution. Execution Phase involves executing the project’s deliverables as planned. Monitoring & Controlling Phase involves tracking progress and managing changes.

Q29. Have you ever worked on a project that did not meet the deadline?

Ans: Missing the deadline or overshooting the budget are two common issues that PM generally encounters. I was working on the Citibank project in London when the Business wanted to add several extra features which were not there in the BRD. It was simply not possible to accommodate all those features otherwise they would have led to missing the deadline as well as overshooting the budget.

After discussing with my team members, I provided the Business with options and work around. They could miss the initial deadline and delay the project’s launch with the added features, or launch it as per plan and add the extra feature in the next release. Business agreed to stick to the original deadline and was happy that I walked them through the options instead of just delaying the project.

Q30. How would you handle the failure of a project?

Ans: As a PM, one should have the ability to handle both successes and failures rationally. I would work with the team to dissect the cause of the failure and use it as a learning moment. I would also ensure that the failure does not impact the morale of the team and the workplace. Handling a project failure requires a structured approach to minimize damage, extract lessons, and rebuild trust.

I will acknowledge the mistake, be transparent and communicate promptly with stakeholders without blaming anybody. I will try to identify the root causes and based on the findings,  take the corrective steps. I will propose a recovery plan and rebuild momentum.

Q31. Can you explain how you would manage projects remotely while working from home?

Ans: I focus on timely communications with all team members. I set remote working guidelines and weekly goals so that my team members know what is expected and continue to work productively, even when they are not physically present in the office. I would conduct weekly meetings to discuss the week’s goals, updates and problems. I will keep my team members motivated and engaged.

Q32. When would you escalate an issue?

Ans: If I have the resources, then my first course of action is to solve it with my immediate team. If the issue at hand is sensitive and requires high-level approval, then I will escalate it and bring it to the notice of the management. Ultimately, I believe that my team and I would be required to use every resource available to solve the issue before escalating it.

Q33. What are the main reasons for project failures?

There are several reasons for project failures. Some of the reasons for the failure of a project could be:

Ans: Poorly defined requirements, Unrealistic expectations, weak leadership and poor decision making, Poor planning and unclear goals, Improper implementation, Miscommunication between team members and end users, Ignoring potential risks, Half-baked efforts of the team and Wrong Technology selection, Unrealistic budget and time expectations, Lack of user involvement.

Q34. Tell me about yourself.

Ans: I would describe myself as resilient, agile & positive minded person and driven by a desire to succeed. I would describe myself as highly curious, focused and motivated person, learning from all parts of life, personal and professional. In my professional life, I look for the challenging problems to solve and where I can learn and develop and contribute the most. I’ve worked on many different types of projects, totally new across the globe and have been able to deliver the goods. No matter what I’m working on, I’m very invested. I am a team leader and believe in people management. I identify anyone I can learn from, as well as problems that I care about and try to optimize every step of the process. I am a fast learner and that’s why I was able to work in different Banks across the globe with diverse culture and working conditions. In my personal life, I spend a lot of time reading and usually have a focused area of interest for a longer period of time. I also love to travel, listen to music, cook with friends, and spend a lot of time running and being physically active outdoors. 

Q35. Can you tell me about a time where you encountered a business challenge? How did you overcome it? Tell me about a time you made a mistake or experienced a failure and how you dealt with it.

Ans: Well, I encountered several challenges during the entire duration of my career and it is simply not possible to capture them in such a short span. Starting with Bank of India Mutual Fund, the Portfolio was very lopsided and too much diversification had been done (invested in 50 Industries and more than 300 stocks) which was counter-productive. The NAV was 150 in 1995 at the time of my joining the company and while the guaranteed redemption value at maturity was 400 in Aug 2000. The Sponsor of Mutual Fund, Bank of India was facing bankruptcy because of guaranteed liability of Rs 10Billion in 1995.We were able to meet the target much before the deadline after massive portfolio restructuring, disinvestment and reinvestment. We reduced the investment to 15 Industries and 40-50 Stocks only. I was successful in introducing Quantitative Analysis, Technical Analysis, Plant & Management Meeting, Z Score & Modified Duration in the Mutual Fund after initial resistance from the staff.

While working at Citibank Singapore in 2006, I faced time management & delivery issues. My Chinese Boss believed in Kai Zen, Just In Time & Zero Defect concepts. She was Asia Pacific Command Centre Head and responsible for launching CitiDirect all over the world. These are fantastic concepts but very difficult to achieve in real life. I used to have issues initially but later on learned to prioritize the work & used to concentrate on the most important ones first. Working with her, I learnt how to manage projects effectively and efficiently.

While working at London, I faced resource crunch, System Outage & non-availability of UAT Environments despite informing everyone else well in advance. Going forward, I started copying everyone and their Superiors also and got the confirmation over mail well in advance.

In Credit Suisse and Lloyds Bank London, I was facing acute difficulties in getting the functional and technical documents. After lot of deliberations with Treasury, Product, Risk & Valuation and Senior stakeholders, Developers, Traders, Vendors, I prepared the Functional and Data Dictionary Documents through data analysis, interviews, discussions , screenshots, code review and reverse engineering.

Q36. What are the most important things you are looking for in your next role?

Ans: I am looking for a challenging & conducive work culture, a competitive salary, future growth potential, sustainable self and organisational growth with topline and bottomline improvement. I value results-driven environments with trust-based deadlines. I’m seeking a role where I can leverage my risk management skills to drive high-stakes projects, with opportunities to lead and manage E2E implementation. I prefer cross cultural global organisation.

Q 37. Can you explain the concept of risk management and its importance in the banking industry?

Ans: Risk management in banking is the process of identifying, assessing, prioritizing and mitigating potential risks that could impact the success of a project. Banks operate in a dynamic environment where they are impacted by various risks, such as credit, market, legal, liquidity, operational & Reputational risks. It’s crucial in the banking industry to ensure compliance, protect assets, and achieve project objectives. Effective risk management allows banks to navigate uncertainties and make informed decisions while adhering to regulatory standards.

Q 38. What strategies do you employ to mitigate different types of risks in a banking project?

Ans: I adopt a comprehensive approach, including risk avoidance, risk transfer, and risk reduction strategies. For instance, if there’s a compliance risk, I work closely with legal experts to ensure adherence. For example, if there’s an operational risk, I might implement additional process controls or redundancies. Regular communication with stakeholders is key to keeping everyone informed about potential risks and the strategies in place to mitigate them.

Q 39. How do you communicate risks and mitigation strategies to stakeholders, including non-technical team members or executives?

Ans: There is no fixed method. Communication has to be tailor made, based on the audience. For non-technical team members and executives, I provide concise summaries focusing on business impact and implications. Clear and transparent communication ensures that everyone understands the risks and the steps we’re taking to manage them and everyone is informed and aligned on risk management efforts.

Q 40. How do you integrate risk management into the overall project planning process?

Ans: Risk management is an integral part of project planning from the beginning. I try to identify potential risks during the planning phase, allocate resources for mitigation strategies, and establish a framework for continuous monitoring. This proactive approach helps anticipate and address risks throughout the project lifecycle.

Q 41. How do you monitor and report on risks throughout the project lifecycle?

Ans: I will try to establish a robust monitoring system that includes regular risk assessments, status reports, and key performance indicators. This allows for real-time tracking of risks and enables prompt adjustments to mitigation strategies. I provide regular updates to stakeholders, ensuring transparency and alignment with project objectives.

Q 42. How do you foster a risk-aware culture within a project team?

Ans: I like open communication and prefer to create an environment where team members feel comfortable reporting risks without fear of blame. Regular training sessions on risk management principles and involving team members in the risk identification process help instill a risk-aware culture. Team collaboration is essential in addressing and mitigating risks effectively.

Q 43. Can you walk me through your process for conducting a risk assessment in a banking project?

Ans: I start by identifying potential risks across categories like credit, market, and operational risks. We then assess the likelihood and impact of each risk, prioritizing them based on their significance to the project. This process involves thorough analysis, expert input, and scenario planning to ensure a comprehensive understanding of potential risks.

Q44. Do you have an understanding in the numerical methods – particularly in change of variables such as Jacobian transformation) or finite difference methods?

Ans: Jacobian is the determinant of the Jacobian matrix. The matrix contains all the first order partial derivatives of a vector function. The main use of Jacobian is found in the transformation of coordinates. It deals with the concept of differentiation with coordinate transformation.

The Jacobian of the transformation x= 𝑔 (𝑢, 𝑣, w), y= h (u, v) is a determinant of a 2×2 matrix is given below:

The Jacobian of the transformation x= 𝑔 (𝑢, 𝑣), y= h (u, v, w), z = k (u, v, w) is a   determinant of a 3×3 matrix is given below:

 Finite difference methods convert ordinary differential equations (ODE) or partial differential equations (PDE), which may be nonlinear, into a system of linear equations that can be solved by matrix algebra techniques. The three types of the finite differences are forward, backward, and central finite differences.

Q45. How comfortable are you with FRTB SA? Are you aware of the bump size and type of shocks that are used for finding the FRTB sensitivities? 

Ans: I am fine with FRTB SA. We measure the sensitivity to the interest rates going up by 1 basis point and then by 100 basis point ignoring any non-linearity. We bump each index curve to measure the Curvature Risk Charge (in Rates) per currency for Options by 240 basis points. 

Q46. Are you familiar with market risk measures? How Basel 2.5 is different from FRTB SA? 

Ans: Yes, I am fully familiar with the market risk measures.

Total SA Capital Requirement = SBM Charge + DRC (Banking Book) + RRAO Charge

Total IMA Capital Requirement = ES +DRC (Credit & Equity Trading Book) + SES Charge

SBA calculates the Delta, Vega and Curvature risks for the 7 Risk Classes GIRR; CSR non-securitisation; CSR- securitisation; CSR- securitisation CTP; FX Risk, Equity Risk & Commodity Risk.

Default Risk Charge captures the jump-to-default risk. It captures the default risk of 3Risk Classes Non-securitisation; Securitisation; Securitisation CTP. Banking book based treatment of default risk and takes into account different hedging effects.

Residual Risk Add On (RAO) – Risk weights applied to notional amounts of instruments with non-linear payoffs (options).

Q47. Have you conducted methodology testing and monitoring exercise? 

Ans: Yes, I have conducted methodology testing and monitoring exercise while working at different banks. Check stability of data used for modelling. Conduct calibration tests of model in order to assess the differences between estimated and realized defaults. Assess the discriminatory power of qualitative & quantitative factors used in staging. 

Q48. How do you address the findings if any in the methodology after testing? 

Ans: If any deviations are found in the methodology after testing, it is highlighted to the Senior Management for further discussion and future course of action to be taken. Root Cause Analysis is done for the deviations and limitations of the Models are discussed along with solutions. Upon approval by the relevant stakeholders, remedial actions are taken.

Q49. How would you align technology strategy with the overall business strategy of the bank?

Ans: As a CTO, my primary responsibility will be to ensure that technology initiatives and investments are aligned with the bank’s business objectives. First of all, I would like to understanding the bank’s strategic goals and then work closely with key stakeholders to identify areas where technology can support and drive those goals. By collaborating with stakeholders and understanding their requirements, I would like to develop a comprehensive technology roadmap that aligns with the bank’s vision, enhances operational efficiency, and delivers innovative solutions to customers.

Q50. How would you ensure data security and regulatory compliance within the bank’s technology infrastructure?

Ans: Data security and regulatory compliance are paramount in the banking industry. To ensure data security, implementation of robust security measures such as encryption, access controls, and regular security audits are required. Additionally, I would establish a strong governance framework to monitor and manage risks related to data privacy and cybersecurity. Staying up-to-date with regulatory requirements and collaborating with legal and compliance teams would be crucial to ensure the bank’s technology infrastructure adheres to all relevant regulations and industry best practices.

Q51. How would you drive digital transformation within the bank?

Ans: I think, digital transformation is essential in today’s banking landscape. To drive this transformation, I would focus on several key areas. First, I would like to understand the bank’s existing technology infrastructure and identify opportunities for modernization and automation. This could involve implementing cloud-based solutions, adopting emerging technologies like artificial intelligence and blockchain, and improving the bank’s digital channels and customer experience. I would also prioritize agility by fostering a culture of innovation, encouraging cross-functional collaboration, and leveraging agile methodologies to accelerate project delivery.

Q52. How will you manage technology budgets and prioritize technology investments?

Ans: Managing technology budgets requires a strategic and data-driven approach.

Q79. What is SaaS?

Ans: SaaS is a software as a Service delivery model. SaaS is a cloud computing model where software applications are hosted and managed by a third-party provider and delivered to users over the internet, typically on a subscription basis. Instead of installing and maintaining software locally, users access it via a web browser or API. It is software offered by the provider on the web. The provider manages the infrastructure and security. Some examples are Microsoft 365, Salesforce, Dropbox, GitHub.

Q80. Can you explain the different types of cloud computing models?

Ans: The three types of cloud computing models are public, private, and hybrid. Public clouds are owned and operated by a third-party service provider, and they make their resources available to the general public over public internet. Examples of Public Clouds are Azure, AWS, GCP.

Private clouds are owned and operated by a single organization, and they are not made available to the general public. This could be on-premises or hosted. Examples of Private cloud are VMware, OpenStack, IBM Cloud Private.

Hybrid clouds are a combination of public and private clouds, and they allow organizations to use both internal and external resources. Examples are AWS Outposts, Azure Stack, Google Anthos.

Q81. How can we differentiate between IaaS, PaaS, and SaaS?

Ans: IaaS, PaaS, and SaaS are all types of cloud computing. IaaS is Infrastructure as a Service, and it provides users with access to a virtualized computing environment. PaaS is Platform as a Service, and it provides users with access to a platform that they can use to develop and deploy applications. SaaS is Software as a Service, and it provides users with access to a software application that they can use.

Q82. What are the advantages of using SaaS over other cloud-based models?

Ans: Software-as-a-Service (SaaS) dominates the cloud landscape for businesses due to its ease of use, cost efficiency, and scalability. No upfront hardware and software costs involved, thus lowering the overall IT overhead. Instant access, no technical expertise needed and provides seamless integration. It gives automatic scaling, global accessibility and customization via Configuration (without Code). SaaS provides pay-as-you-go pricing, and increased flexibility. SaaS also offers a number of benefits in terms of security and compliance and lets companies focus on product and operations instead of IT.

Q83. What’s your understanding of multi-tenancy in the context of SaaS?

Ans: Multi-tenancy is a key concept in the world of SaaS. In a nutshell, it refers to the ability of a single instance of a software application to serve multiple tenants. In other words, each tenant has their own dedicated space within the application, with isolated data and configurations. This is in contrast to a single-tenant setup, where each customer would have their own instance of the software. The right approach depends on security needs, cost, and customization depth. Real world multitenancy examples are Salesforce, Slack and Shopify.

Q84. What do you understand about Application Programming Interfaces (APIs)?

Ans: API is a set of programming instructions that allow software to interact with other software. This can include retrieving data from a database, sending data to a web server, or even just displaying data on a screen. APIs are a key part of how software applications are able to talk to each other and share data. APIs form the backbone of modern app development, cloud services and identity management.

Q85. Can you give me some examples of real-world applications that use APIs to communicate with third-party services?

Ans: Some examples of real-world applications that use APIs to communicate with third-party services include social media applications that allow users to post updates to their Facebook or Twitter feed, or weather applications that display the current forecast from a weather service. Other examples are Google Maps API, Bloomberg Market Data API, Tesla API, Spotify API, YouTube API.

Q86. Why do you think it’s important for companies to have a strategy around their API usage?

Ans: There are several reasons for companies to have a strategy around their API usage. APIs can be monetized directly. APIs allow third-party developers to build integrations, extending the product’s reach. APIs streamline communication between teams and microservices, reducing silos. A well-designed API strategy lets companies grow faster. An API strategy enforces governance and simplifies compliance with standards like GDPR. Moreover, it allows them to better control how their data is being used and accessed. It helps to ensure that only authorized users are able to access the data. And finally, it can help to prevent data breaches by making it more difficult for unauthorized users to access the data.

Q87. Is it possible to build an application without using any third party APIs? If yes, then how?

Ans: Yes, it is possible to build an application without using any third party APIs. However, it would likely be a very basic application with limited functionality. Third party APIs provide a way to extend the functionality of an application by accessing data and services from other sources. Without using any third party APIs, an application would be limited to the data and services that it could provide itself.

Q88. What are the main areas of concern while building an API?

Ans: Building an API involves several critical areas of concern to ensure it is secure, scalable, maintainable, and user-friendly. The main areas of concern are given below:

1. Security related to Authentication & Authorization, input validation and sanitization. Data privacy and compliance while handling sensitive data. 

2. Performance & Scalability related issues like efficient data handling, pagination, filtering, and sparse field setting. Load balancing and database optimization.

3. API Design & Usability issues RESTful Principles, consistent naming & versioning, clear documentation and error handling.

4. Reliability & Monitoring issues like Analytics, circuit breakers and SLA and uptime, response time guarantees.

5. Maintainability & Extensibility issues like Microservices or well-structured monoliths. Automated Testing like unit, integration, and load tests (Postman, Jest, Locust).

6. Deployment & DevOps issues like containerization & orchestration: Docker, Kubernetes. Blue-Green/Canary Deployments to minimize downtime during updates.

7. Business & Legal Concerns like rate limiting for monetization, Terms of Service & API Licensing and Audit Trails.

Q89. Is it a good idea to expose our database through an API?

Ans: There is no easy answer to this question, as it depends on a number of factors. For example, if your database contains sensitive information, then it is probably not a good idea to expose it through an API. On the other hand, if your database is simply used to store data that is not sensitive, then exposing it through an API could be a good way to allow others to access that data. Ultimately, it is up to you to decide whether or not exposing your database through an API is a good idea, based on the specific needs of your project.

Q90. What are some common security concerns associated with exposing data via an API?

Ans: One of the most common security concerns associated with exposing data via an API is the potential for data breaches. If an attacker is able to gain access to the API, they could potentially access sensitive data that is being exposed. Another concern is the potential for denial of service attacks, where an attacker could overload the API with requests in an attempt to take it down.

Q91. What is RESTful architecture?

Ans: RESTful architecture is a way of designing software that takes advantage of the web. It is based on the idea of resources, which are identified by Uniform Resource Identifiers (URIs). These resources can be manipulated using a set of standard methods, such as GET, POST, PUT, and DELETE. REST was developed as a response to what some see as SOAP’s shortcomings—primarily SOAP’s strict reliance on XML. REST APIs can send messages in various formats and languages, like CSV (comma-separated value) files to JSON (a JavaScript-derived language with similarities to XML).

Q92. What is JSONP?

Ans: JSONP is a method for making cross-domain requests from web browsers. It stands for “JSON with Padding.” Normally, web browsers are only able to make requests to the same domain that they are currently on. However, JSONP allows for requests to be made to other domains, as long as the response is wrapped in a function call. This function call is then executed by the browser, and the results are displayed on the page.

Q93. What should be done if the client needs to make multiple requests to perform an operation?

Ans: There are a few things that can be done if the client needs to make multiple requests to perform an operation. One option is to use a batch request, which allows the client to send multiple requests in a single HTTP request. Another option is to use a persistent connection, which keeps the connection open for a period of time so that multiple requests can be made without having to establish a new connection each time.

Q94. Is it recommended to create custom HTTP headers?

Ans: There is no definitive answer to this question, as it depends on the specific needs of the application. However, in general, it is considered a good practice to create custom HTTP headers when one needs to add extra information to client’s requests or responses. This allows one to keep the application’s data well-organized and makes it easier for other applications to interface with data.

Q95. What are the best practices when it comes to designing an API?

Ans: When it comes to designing an API, there are a few best practices to keep in mind. First, make sure that your API is well documented so that developers know how to use it. Second, design your API to be flexible and extensible so that it can be easily integrated into different applications. Finally, make sure that your API is secure so that sensitive data is not compromised. Be consistent with naming, HTTP methods, and status codes. Prioritize security (HTTPS, OAuth, rate limiting). Optimize for performance (pagination, caching, compression). Document everything and provide examples. Plan for evolution (versioning, deprecation policies).

Q96. What do you know about pagination in APIs?

Ans: Pagination is a way of handling large result sets from an API by breaking the results down into smaller, more manageable chunks, or pages. This allows for better performance and scalability, as well as a better user experience, since the user is not overwhelmed with too much data at once. To implement pagination, the API will need to support some sort of limit and offset parameters, which will tell the API how many results to return per page, and where to start in the overall result set.

Q97. What is the difference between SOAP and REST?

Ans: SOAP (Simple Object Access Protocol) is a standards-based web services access protocol that has been around for a long time and being used with legacy systems. REST (Representational State Transfer) is newer, and is based on the idea of resources being accessed via a URL. REST is generally simpler and easier to work with than SOAP, and is more suited to modern web applications. The differences are given below:

Protocol & Standards	SOAP	REST
	A protocol with strict standards (XML, WSDL, WS-Security).	An architectural style (not a protocol), using HTTP loosely.
	Uses XML only for data format.	Supports JSON (common), XML, HTML, or plain text.
	Requires WSDL (Web Services Description Language) to define API contracts.	No formal contract required. Relies on HTTP verbs (GET, POST, etc.) and URIs.
Communication & State	Stateful or stateless (depends on implementation).	Stateless by design (each request is independent).
	Uses SOAP envelopes (header + body) for messages.	Uses HTTP methods directly (e.g., GET /users).
	Supports ACID transactions (critical for banking/enterprise).	Relies on HTTP status codes (200 OK, 404 Not Found).
Performance & Flexibility	Heavyweight (XML parsing adds overhead).	Lightweight (JSON is faster to parse).
	Built-in retry logic and error handling (WS-Reliable Messaging).	Depends on HTTP retries (no built-in reliability).
	Less cacheable (due to stateful operations).	Highly cacheable (uses HTTP caching mechanisms).
Security	Built-in WS-Security (encryption, signatures, SAML).	Relies on HTTPS, OAuth 2.0, JWT.
	Better for enterprise-grade security (e.g., banking).	Simpler but requires manual implementation.
Use Cases	Enterprise systems (banking, healthcare, legacy apps).	Web/mobile apps, public APIs (Twitter, GitHub).
	High-security transactions (payment processing).	Scalable, stateless services (cloud, microservices).
	Complex operations (airline reservations).	CRUD operations (Create, Read, Update, Delete).

Q98. What happens if there are two or more conflicting requirements for an API endpoint?

Ans: In the event that there are two or more conflicting requirements for an API endpoint, the SaaS provider will typically work with the customer to determine which requirement is more important. In some cases, the SaaS provider may be able to create a custom solution that meets both requirements. The approach depends on the nature of the conflict, business priorities, and stakeholder needs.

Identify the Type of Conflict- whether it relates to Functional Conflicts or Security vs. Usability Conflict or Performance vs. Features Conflict or Versioning Conflict. Provide resolution strategies based on business goals. Provide flexible design patterns, creating separate endpoints for different needs. Some Real-world Examples could be Pagination vs. Full Export, Authentication Strictness, Performance vs. Real-Time Data.

SOAP (Simple Object Access Protocol) is one of the oldest web service APIs still in use today. Originally developed by Microsoft in the Web 1.0 era, SOAP is now an open standard as defined by W3C. SOAP first gained popularity because it delivers messages via HTTP (the web language) in the cross-platform XML language. When much of the web was built on proprietary technology, a SOAP API’s ability to send and receive XML data across any platform and operating system was a breakthrough. SOAP remains in wide use today because of its tight security standard.

Q99. What are the different types of APIs?

Ans: The different types of APIs are given below:

1. By Architecture/Protocol

a) REST (Representational State Transfer)

• HTTP-based, stateless, uses standard methods (GET, POST, PUT, DELETE).
• Data formats: JSON (common), XML.
• Example: Twitter API, GitHub API.

b) GraphQL

• Query language for APIs (developed by Facebook).
• Clients request only the data they need.
• Example: Shopify API, GitHub GraphQL API.

c) SOAP (Simple Object Access Protocol)

• XML-based, strict standards.
• Example: PayPal API, legacy enterprise systems.

d) gRPC (Google Remote Procedure Call)

• Uses Protocol Buffers (binary format) for high performance.
• Supports streaming (real-time updates).
• Example: Microservices, IoT, cloud-native apps.

e) WebSocket

• Real-time, bidirectional communication (over a single TCP connection).
• Example: Chat apps (Slack), live sports updates.

2. By Use Case

a) Open APIs- Also known as a Public API, this describes publicly available APIs. Access is open to all API developers and users on the internet.

• Example: Twitter API, Google Maps API.
• Often require API keys or OAuth.

b) Private APIs- Also known as an Internal API, this category of API is restricted for use inside an organization only and is not available on the public internet. Private APIs typically exist to enhance employee workflows or share data amongst on-premise hardware.

c) Partner APIs- Unlike Public APIs, Partner APIs are not open to everyone. Developers need to be granted access to these APIs.

• Shared with specific business partners (payment gateways).
• Requires authentication and contracts.

d) Composite APIs- This type of API combines multiple APIs’ different services and data into a single call. These APIs are seen as especially efficient for accomplishing multiple tasks at once.

3. By Data Format

a) JSON APIs-Lightweight, easy to parse (used in REST/GraphQL).

b) XML APIs-Used in SOAP, older enterprise systems.

c) Binary APIs-High-performance (e.g., gRPC, WebSockets with binary frames).
