01
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.
A RAID log tracks Risks, Assumptions, Issues and Dependencies for a project. Each entry has an ID, description, owner, impact, status, mitigation or action, and due date. A risk is something that may happen, an issue is something that has already happened, an assumption is believed true but unverified, and a dependency is something the project needs from others. A BA uses it to record requirement assumptions and dependencies, and reviews it weekly so nothing is silently forgotten.
03
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.
04
Managers want to click a region on a summary report page and jump to a detail page for only that region. How do you build it in Power BI?
Use drill-through. Create a detail page, add the Region field to the page's drill-through filter well, and design visuals for orders, products and trends. Power BI adds a back button automatically. On the summary page, users right-click a region and choose Drill through. Keep all filters on so date selections carry over. For guided navigation, you can also add buttons with bookmarks, but drill-through is the cleanest way to pass the selected region.
05
What is user story mapping and how does it help plan releases?
User story mapping arranges stories in two dimensions. Across the top is the user journey as a sequence of activities, for example search, compare, buy and track. Below each activity, stories are stacked by priority. Drawing horizontal lines across the map creates release slices, where the first slice is a thin end-to-end MVP that covers every step at a basic level. It prevents a flat backlog where teams build one area deeply while the journey stays incomplete.
06
The CEO wants one KPI to judge the customer support team. What would you propose?
A single KPI can be gamed, so I would propose one headline with guardrails. The headline could be first-contact resolution rate, because it reflects solving problems, not just closing tickets. Guardrails would be customer satisfaction score after the ticket and median first response time. I would also watch ticket volume per thousand orders, which shows whether product issues are falling. Review targets quarterly with the support head.
07
A product manager wants to stop an A/B test after three days because the variant is winning. What do you advise?
Advise against it. Checking results repeatedly and stopping at the first significant result inflates false positives, often far beyond the planned 5 percent. Three days also misses weekly patterns and novelty effects. Run the test for the pre-calculated sample size and duration. If speed is critical, the team can use a sequential testing method designed for early looks, but that must be planned before the test starts.
08
Tell me about a time you said no to a stakeholder.
Situation: a regional manager wanted a custom report changed daily, which would have taken half my week. Task: support him without blocking other priorities. Action: I asked which decisions the report fed and found he needed only four numbers. I said no to the custom version, explained the impact on other work, and added those four metrics with a filter to the existing dashboard. Result: he got his numbers the same day and the team kept its capacity.
09
A feature launched two months ago is used by only 4 percent of users. What would you do?
Find out whether it is a discovery problem or a value problem. Check how many users saw the entry point, how many tried it and how many returned. If few saw it, test better placement or onboarding prompts. If many tried and few returned, interview users and review session recordings to understand why. Also check if the 4 percent are high-value users. Then decide to improve, reposition or remove it.
10
Tell me about a time you mapped a process and discovered a major inefficiency.
Situation: vendor onboarding at my company took around 18 days and procurement blamed finance. Task: I was asked to map the AS-IS process. Action: I interviewed five roles, traced 25 recent vendor records through system timestamps and built a swimlane map. It showed that bank details were collected twice and verified by two teams separately. Result: we merged the steps into one checklist at intake, cut onboarding to 9 days and reduced rework emails by about half.
A BA bridges business and technology: gathers requirements, analyses data and processes, documents BRD/FRD and makes sure the final solution actually solves the business problem.
12
A KPI on your dashboard dropped 40 percent overnight. What are your first steps?
Assume a data problem until proven otherwise, because real businesses rarely move 40 percent in a day. Check whether the refresh completed, whether source row counts look normal, and whether any tracking, pipeline or definition changed. Compare with a raw source query and a related metric, such as orders versus payments. If the data is fine, segment by channel, region and platform to locate the drop, then alert the owners quickly.
13
Daily active users dropped 10 percent week over week. How do you investigate?
Rule out data issues first: tracking changes, app release bugs, pipeline delays or bot filters. Check whether the drop is seasonal by comparing with the same week last year or a festival calendar. Then segment by platform, app version, country or city, acquisition channel and new versus returning users to locate it. Look at the funnel for the core action. Connect findings to releases, outages or marketing changes, then recommend fixes.
14
What is the difference between bookings, billings and revenue?
Bookings are the value of contracts signed in a period, showing future commitment. Billings are the amounts invoiced to customers in the period. Revenue is what is earned and recognised under accounting rules as the service is delivered. Example: a 3-year contract worth 36 lakh signed in April is 36 lakh in bookings, 12 lakh in billings if invoiced annually, and only 1 lakh in revenue for April. Confusing them is common when reporting sales performance.
15
What is a date table in Power BI and why should you mark it as a date table?
A date table has one row per day with no gaps, plus columns like Year, Quarter, Month, Week and Fiscal Period. It is related to the fact table date column. Marking it as a date table tells Power BI to use it for time intelligence functions like TOTALYTD, SAMEPERIODLASTYEAR and DATESINPERIOD, which require a continuous date range. It also gives consistent month sorting and fiscal calendars across every report.
Value chain analysis breaks a business into the activities that create value: primary activities such as inbound logistics, operations, outbound logistics, marketing and sales, and service, plus support activities like procurement, technology, HR and infrastructure. For each activity you look at cost and differentiation. In cases it helps locate where costs are rising or where a competitive advantage can be built, for example in last-mile delivery.
17
Tell me about a time you worked under a tight deadline.
Situation: in my final-year project, our client moved the presentation forward by a week. Task: finish the analysis and dashboard in four days instead of eleven. Action: I listed the must-have outputs, split work across the team, cut two nice-to-have charts and checked numbers every evening. Result: we presented on time, the client used our recommendations, and I learned to prioritise ruthlessly and confirm what is truly essential.
Use one pool for the company with lanes for Employee, Manager and HR system. Start event: leave request submitted. Task: system checks leave balance. Exclusive gateway: balance sufficient? If no, end event that notifies the employee. If yes, user task: manager reviews. Add an interrupting timer boundary event of 3 days that escalates to the skip-level manager. Gateway: approved or rejected. Approved path updates the leave balance and calendar, then both paths notify the employee and end.
20
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.
21
Write a user story with acceptance criteria for password reset.
As a customer, I want to reset my password by email so that I can get back into my account.
Acceptance criteria:
• Reset link expires in 15 minutes
• Password rules are shown while typing
• A success message appears after reset
22
Your TO-BE process cuts the account-opening cycle time by half, but the compliance team rejects it. How do you handle it?
Ask compliance which specific controls they believe are weakened, and map each regulatory requirement to steps in the old and new flows. Often the control can be kept in a different form, such as automated checks, risk-based sampling or a post-approval audit instead of a manual pre-check. Bring compliance into the redesign rather than presenting a finished model. Document the agreed controls in the TO-BE diagram so audit can trace them. Speed never overrides a mandatory control.
23
Your AS-IS map of a loan approval process shows 14 handoffs between teams. How do you identify improvements?
First measure each handoff: waiting time, rework rate and volume, using system timestamps where possible. Then classify steps as value-adding, required for compliance or waste. Look for patterns: repeated approvals, information re-entered in two systems, work bouncing back for missing documents. Typical fixes are merging roles, adding a checklist at intake so applications arrive complete, parallelising checks and automating rule-based approvals. Quantify the expected reduction in cycle time for each option.
24
Write a SQL query to find requirements that have no linked UAT test case.
SELECT r.req_id, r.title, r.priority
FROM requirements r
LEFT JOIN test_case_links l ON l.req_id = r.req_id
WHERE l.req_id IS NULL
AND r.status = 'APPROVED'
ORDER BY r.priority;
-- Run this before UAT starts: every approved requirement
-- should trace to at least one test case.
A live connection queries the source database every time the view changes, so data is current but speed depends on the database. An extract (.hyper file) is a compressed snapshot stored by Tableau that is fast to query and can be refreshed on a schedule, but it is only as fresh as the last refresh. Extracts suit large, slow or remote sources; live suits fast warehouses and real-time needs.
27
What is the logical order in which a SQL SELECT query is executed?
Logically the database processes FROM and JOIN first, then WHERE, GROUP BY, HAVING, SELECT, DISTINCT, ORDER BY and finally LIMIT or TOP. This explains common errors: you cannot use a SELECT alias in WHERE because WHERE runs earlier, aggregate conditions must go in HAVING, and window functions cannot be filtered in WHERE, so you wrap them in a CTE or subquery. The optimiser may physically reorder steps, but the result follows this order.
28
What is the difference between ROW_NUMBER, RANK and DENSE_RANK?
All three number rows within a window ordered by a column. ROW_NUMBER gives a unique sequence 1, 2, 3 even for ties. RANK gives ties the same number and then skips, so 1, 1, 3. DENSE_RANK gives ties the same number without gaps, so 1, 1, 2. Use ROW_NUMBER to pick exactly one row per group, such as the latest order, and DENSE_RANK for 'top 3 distinct salary levels' type questions.
29
A manager says the dashboard total does not match the finance team's Excel sheet. What do you do?
First agree on the definition: date range, gross or net, tax, returns, currency and which date (order or invoice) is used. Then reconcile at a small grain, such as one month and one region, comparing row counts and sums between the source query and the sheet. Common causes are filters on the page, missing relationships, duplicate rows after a join or a late refresh. Document the agreed definition in the report tooltip.
30
A hospital chain's average patient waiting time has risen from 30 to 50 minutes. How would you approach the case?
Clarify where the wait is measured: registration, consultation, diagnostics or billing. Split the problem into demand and capacity. On demand, check patient volume, peak-hour mix, walk-ins versus appointments and new departments. On capacity, check doctor availability, no-shows of staff, consultation time per patient and process bottlenecks such as manual billing. Identify the biggest stage and suggest fixes like slot-based appointments, triage and digital billing.
31
Write a SQL query for a signup to purchase funnel from an events table.
WITH steps AS (
SELECT user_id,
MAX(CASE WHEN event = 'signup' THEN 1 ELSE 0 END) AS s1,
MAX(CASE WHEN event = 'add_to_cart' THEN 1 ELSE 0 END) AS s2,
MAX(CASE WHEN event = 'purchase' THEN 1 ELSE 0 END) AS s3
FROM events
WHERE event_date >= '2026-10-01'
GROUP BY user_id
)
SELECT SUM(s1) AS signups,
SUM(s1 * s2) AS carts,
SUM(s1 * s2 * s3) AS purchases,
ROUND(100.0 * SUM(s1 * s2 * s3) / NULLIF(SUM(s1), 0), 2) AS conv_pct
FROM steps;
Compare against the baseline you measured before the change, using the same definitions: cycle time, first-time-right rate, cost per case, backlog and customer complaints. Pull data from system timestamps rather than surveys. Check that the gain is not explained by lower volumes or seasonality, ideally by comparing similar periods. Also check for side effects, such as faster processing but more rework downstream. Present the before-and-after with the business owner, and note where adoption is still incomplete.
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.
36
Your monthly Excel report takes a full day of manual work. How would you automate it?
Map the steps first: which files arrive, what cleaning is done and which outputs are needed. Move the import and cleaning into Power Query so a refresh replaces copy-paste. Base calculations on Excel Tables and PivotTables that update automatically, and keep a fixed template for the output. Use a small macro or Office Script only for the remaining formatting or emailing. Add checks such as row counts and totals so errors surface quickly.
37
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.
38
What is the difference between COUNT(*) and COUNT(column)?
Get to the underlying business goal behind the requirement, because the goal is often achievable in another way. Ask developers to explain the constraint and the cost of alternatives. Bring both sides together with options: a simpler version, a phased delivery, a manual workaround or a different design. Show effort, risk and value for each, and let the product owner or sponsor decide. Document the decision.
CALCULATE evaluates an expression under a modified filter context. You pass a measure plus filter arguments that add, replace or remove filters, for example CALCULATE([Sales], 'Region'[Name] = "North") or CALCULATE([Sales], ALL('Product')). It is the basis of time intelligence, percent-of-total and comparison measures. It also triggers context transition when used inside a row context, which is powerful but a common source of confusion.
