01
A ride-hailing app's ride cancellation rate rose from 8 to 14 percent. How would you structure the problem?
First split by who cancels: riders or drivers. For rider cancellations, check wait times, pickup accuracy, price surges and changes in ETA. For driver cancellations, check trip distance, payment mode, low fares, destination visibility and incentive changes. Then segment by city, time of day and area. Link to recent changes like a new pricing rule. Recommend fixes for the largest driver, such as better matching or adjusted incentives.
02
A business tester raises a defect, and the developer closes it as 'works as designed'. How do you resolve it?
Go back to the requirement and acceptance criteria. If the system matches the agreed requirement, the developer is right, and the business need is a change request. If the requirement is unclear or the design misread it, it is a defect, and the requirement wording should be fixed. Discuss it in triage with both parties, using examples. Either way, close the loop with the tester so they understand the outcome and keep trusting the process.
# Yearly cash flows in B2:B7, year 0 investment negative
=IRR(B2:B7)
# Irregular dates: cash flows in B2:B7, dates in C2:C7
=XIRR(B2:B7, C2:C7)
# XIRR returns an annualised rate based on actual dates,
# which suits SIP returns or projects with uneven payments.
05
Developers and testers interpret the same user story differently. How do you fix this?
The story is ambiguous, so bring the three amigos together: BA or product owner, a developer and a tester. Walk through concrete examples, including edge cases and error cases, and write them as acceptance criteria, ideally in Given-When-Then format. Add business rules, sample data and mock-ups where needed. Update the story and use the same practice in refinement for future stories, so gaps are found before coding starts.
Situation: two days before the go-live of a loyalty points system, UAT showed points were doubled for refunded orders. Task: give a clear recommendation at the go or no-go meeting. Action: I presented the defect, estimated financial exposure at about 6 lakh rupees a month and showed the fix needed three days including regression. Result: the sponsor agreed to a one-week delay. The release went live cleanly, and the sponsor later cited the decision as an example of good risk management.
09
Write a SQL query for the top 3 products by revenue in each category.
WITH ranked AS (
SELECT category, product_id, SUM(amount) AS revenue,
DENSE_RANK() OVER (PARTITION BY category
ORDER BY SUM(amount) DESC) AS rk
FROM sales
GROUP BY category, product_id
)
SELECT category, product_id, revenue
FROM ranked
WHERE rk <= 3
ORDER BY category, rk;
10
Describe a time you explained a complex technical topic to a non-technical audience.
Situation: operations managers did not trust a new demand forecast that drove staffing. Task: explain it so they would use it. Action: I avoided model terms and showed how it used last year's same week, recent trend and festival calendar, with a chart of past forecasts against actuals. I compared the forecast range to a weather forecast. Result: managers started using it for rosters and gave feedback that improved it further.
11
Write an Excel formula to count the number of unique customers in a column.
// Excel 365
=COUNTA(UNIQUE(A2:A500))
// unique customers in the North region only
=COUNTA(UNIQUE(FILTER(A2:A500, B2:B500="North")))
// older versions (no blanks in range)
=SUMPRODUCT(1/COUNTIF(A2:A500, A2:A500))
12
What steps do you follow to plan and run a UAT cycle?
Plan: agree scope, entry and exit criteria, testers and schedule with the business owner. Prepare: write scenarios and test cases from requirements, set up the environment and test data, and brief testers. Execute: run test cases in daily sessions, log defects with evidence and hold a daily triage. Monitor: report progress, pass rate and open defects by severity. Close: check exit criteria, get the business sign-off with known issues documented, and hold a short lessons-learned review.
13
What is the novelty effect, and why should A/B tests run for full weeks?
The novelty effect is a temporary lift because users are curious about something new, which fades after a few days; the opposite, change aversion, causes a temporary drop. Running tests for at least one or two full weeks covers weekday and weekend behaviour and lets these effects settle. You can also check whether the lift is stable over time and among new users who never saw the old version.
14
In UAT cycle 2, a feature that passed in cycle 1 is now broken after a defect fix. What does this tell you and what should change?
It is a regression: the fix for one defect broke existing functionality, which usually means changes were not impact-analysed and there is no regression suite. Log it as a new high-priority defect linked to the fix. Agree with the team that every UAT build comes with release notes listing the changes, and that QA runs an automated or core manual regression pack before handing the build to business testers. Also add the broken flow to the UAT regression checklist.
15
Write a SQL query to show cumulative revenue by month.
WITH monthly AS (
SELECT DATE_TRUNC('month', order_date) AS month,
SUM(amount) AS revenue
FROM orders
GROUP BY 1
)
SELECT month, revenue,
SUM(revenue) OVER (ORDER BY month) AS cumulative_revenue
FROM monthly
ORDER BY month;
-- add PARTITION BY EXTRACT(YEAR FROM month) to reset each year
KPIs are ongoing health measures of the business, like monthly revenue, churn or on-time delivery, tracked continuously. OKRs are a goal-setting method: an Objective is a qualitative ambition for a quarter, and Key Results are two to four measurable outcomes that show it was achieved. A KPI that is off track often becomes the subject of an OKR, for example 'reduce churn from 5 to 3 percent this quarter'.
17
Write non-functional requirements for an online payment page.
NFR-01 Performance: the payment page loads within 2 seconds for 95 percent of requests at 500 concurrent users. NFR-02 Availability: 99.9 percent monthly uptime outside planned maintenance. NFR-03 Security: card data is never stored by the application, and all traffic uses TLS 1.2 or higher. NFR-04 Compliance: the flow meets PCI DSS and RBI payment guidelines. NFR-05 Usability: works on mobile screens from 360 pixels wide. NFR-06 Audit: every transaction attempt is logged with a timestamp.
18
Write a DAX measure for the product return rate that avoids divide-by-zero errors.
Return Rate % =
VAR ReturnedQty = SUM ( Returns[Quantity] )
VAR SoldQty = SUM ( Sales[Quantity] )
RETURN
DIVIDE ( ReturnedQty, SoldQty, 0 )
// DIVIDE returns the third argument (0) when SoldQty is zero or blank.
// Format the measure as a percentage in the model.
19
Guesstimate: how many cups of tea are sold in Delhi per day?
Population about 20 million, adult tea drinkers about 50%, cups bought outside per person around 1 on average. This gives roughly 10 million cups, then adjust for offices and stalls.
20
Write Given-When-Then acceptance criteria for applying a discount coupon at checkout.
Given a cart of 1,200 rupees and a valid coupon SAVE10 with a minimum order of 1,000 rupees, when the user applies it, then 10 percent is deducted and the new total is shown. Given an expired coupon, when applied, then the message 'This coupon has expired' appears and the total is unchanged. Given a cart below the minimum, when applied, then the user is told how much more to add.
21
UAT starts tomorrow, but the business has not nominated any testers. What do you do?
Escalate immediately to the business sponsor with the impact: each day without testers delays sign-off and go-live. Ask for named testers with protected time, even part-time. Meanwhile, prepare so no time is lost: finalise test cases, check the environment and data, and plan a short tester briefing. If testers cannot be released, propose re-planning UAT dates rather than letting IT or the BA test on the business's behalf, because acceptance must come from the users.
22
A client's profits are falling. How do you structure the problem?
Split into revenue and cost, then revenue into price, volume and mix, and cost into fixed and variable; check internal factors and external market factors.
23
What is an issue tree and how does a hypothesis-driven approach work?
An issue tree breaks the main question into smaller, MECE sub-questions until each can be answered with data, such as 'why are profits down?' into revenue and cost branches. A hypothesis-driven approach starts with a likely answer, for example 'profit fell because delivery costs rose', and uses the tree to decide which data proves or disproves it first. It focuses effort and keeps the case structured and fast.
24
A bank's mobile app logins increased, but digital transactions fell. What could explain this?
Users are coming but not completing transactions, so look at the gap. Possible causes: a release that broke a payment flow, new security steps like extra OTPs adding friction, logins driven by balance checks or offers, or transactions shifting to another channel. Compare the funnel from login to transaction by app version and device, check failure and error rates, and review support complaints before recommending fixes.
25
What is an impact-effort matrix and how do you use it to prioritise recommendations in a case?
An impact-effort matrix is a 2x2 grid that plots options by expected business impact against effort, cost or time. High impact and low effort are quick wins to do first; high impact and high effort are major projects to plan; low impact and low effort are fill-ins; low impact and high effort should be dropped. In a case interview, it helps you end with a clear, prioritised recommendation rather than a long list of ideas.
A balanced scorecard is a strategic performance framework that tracks objectives and KPIs across four perspectives: financial (revenue growth, margin), customer (NPS, retention), internal processes (cycle time, defect rate) and learning and growth (training hours, employee engagement). The idea is that financial results are lagging, so leaders also need leading measures of what drives future performance. A strategy map links the objectives with cause-and-effect arrows from people to processes to customers to financial outcomes.
27
Tell me about a time a SQL query you wrote gave wrong results. How did you catch it?
Situation: my weekly sales report showed a 12 percent jump that no one could explain. Task: verify the number before it reached leadership. Action: I compared row counts before and after each join and found a new promotions table had multiple rows per order, duplicating revenue. I aggregated promotions per order first and added a test comparing totals with the source. Result: the corrected report went out the same day, and I now check grain on every new join.
// Dates in Sales[Date], amounts in Sales[Amount]
=SUMIFS(Sales[Amount],
Sales[Date], ">=" & EOMONTH(TODAY(), -1) + 1,
Sales[Date], "<=" & TODAY())
// EOMONTH(TODAY(),-1)+1 gives the first day of the current month
30
Leadership wants to automate an invoice approval process with RPA. What do you check in the process model before agreeing?
Check that the process is stable, rule-based and high volume, with structured digital inputs. Look at the variant rate: if half the cases are exceptions handled by judgement, a bot will fail often. Verify that the underlying systems and screens will not change soon. Fix the process first, because automating a broken flow only makes errors faster. Finally estimate hours saved against bot build and maintenance cost, and define how exceptions get routed to people.
Create a shared, certified semantic model with one definition per KPI, built on a governed warehouse layer. Departments build thin reports on top of it through live connection instead of copying data. Set up workspaces by environment (dev, test, prod), deployment pipelines, naming standards, a KPI glossary and owners for each measure. Keep a small central team for the core model and let departments self-serve on top, which balances control and speed.
33
What are process levels such as L0 to L4 in a process architecture?
Process levels organise models from broad to detailed. L0 shows the value chain or main process areas, such as Order to Cash. L1 and L2 break these into process groups and end-to-end processes, such as Credit Management. L3 shows the detailed BPMN flow with roles and decisions. L4 covers work instructions or system steps. A level structure keeps hundreds of diagrams consistent, avoids duplicates and lets executives and operators each read the right depth.
34
What is a cutover plan and a go-live readiness checklist?
A cutover plan is an hour-by-hour runbook for moving from the old system to the new one: freezing old transactions, final data migration, validation checks, configuration, smoke testing, switch-over and a rollback plan with clear decision points. A go-live readiness checklist confirms that UAT is signed off, users are trained, support and hypercare are staffed, data is reconciled, and communications are sent. The go or no-go meeting reviews this checklist before the cutover starts.
35
Write a SQL query for a 7-day rolling average of daily revenue.
WITH daily AS (
SELECT order_date, SUM(amount) AS revenue
FROM orders
GROUP BY order_date
)
SELECT order_date, revenue,
AVG(revenue) OVER (ORDER BY order_date
ROWS BETWEEN 6 PRECEDING AND CURRENT ROW) AS rolling_7d
FROM daily
ORDER BY order_date;
-- fill missing dates from a calendar table first, or gaps skew the average
36
Write a SQL query for Day-7 retention by weekly sign-up cohort.
WITH cohort AS (
SELECT user_id, signup_date,
DATE_TRUNC('week', signup_date) AS cohort_week
FROM users
),
ret AS (
SELECT DISTINCT c.user_id
FROM cohort c
JOIN events e ON e.user_id = c.user_id
AND e.event_date = c.signup_date + INTERVAL '7 day'
)
SELECT c.cohort_week, COUNT(*) AS users,
ROUND(100.0 * COUNT(r.user_id) / COUNT(*), 1) AS d7_retention_pct
FROM cohort c
LEFT JOIN ret r ON r.user_id = c.user_id
GROUP BY c.cohort_week
ORDER BY c.cohort_week;
37
How would you size the market for IT courses in Delhi NCR?
Top-down: NCR population aged 18–30 × share of graduates × share wanting paid upskilling × average fee. Cross-check bottom-up with institutes × batches × students × fees. State your assumptions.
A defect is logged as New with steps, expected and actual results, and evidence. It is reviewed in triage and moves to Open or Assigned, or to Rejected, Duplicate or Deferred. The developer fixes it and marks it Fixed or Ready for retest. The tester retests: if it passes it moves to Closed, and if not it is Reopened. Tracking status and age helps the UAT lead report readiness and spot defects stuck too long.
39
Revenue grew but profit fell. Why could that happen?
Look at the cost side: heavier discounts, higher CAC, logistics costs, product mix shifting to low-margin items, one-time expenses or pricing changes. Break contribution margin down by segment.
40
You must gather requirements to replace a 15-year-old legacy system with no documentation. How do you approach it?
Combine several sources. Interview and observe users doing real tasks, and review screens, reports and outputs to infer business rules. Analyse the database and logs to see which data and functions are actually used. Work with long-serving staff and IT support for hidden rules and workarounds. Build AS-IS process maps, decide what to keep, drop or improve, and validate the findings with users. Plan data migration requirements early.
