01
Write a SQL query to find the percentage of orders delivered late in each city.
-- late = delivered after the promised date
SELECT
city,
COUNT(*) AS total_orders,
SUM(CASE WHEN delivered_at > promised_at THEN 1 ELSE 0 END) AS late_orders,
ROUND(100.0 * SUM(CASE WHEN delivered_at > promised_at THEN 1 ELSE 0 END)
/ COUNT(*), 2) AS late_pct
FROM orders
WHERE status = 'DELIVERED'
GROUP BY city
ORDER BY late_pct DESC;
02
What is a business case document and what does it contain?
A business case justifies why an organisation should invest in a project. It usually contains the problem or opportunity, objectives and success measures, options considered including do nothing, costs and benefits of each option with a financial evaluation such as NPV and payback, risks and assumptions, impact on people and processes, a recommended option and an implementation timeline. A BA often builds it with finance, and it becomes the baseline for checking benefits after delivery.
03
The scheduled refresh failed overnight and leadership reviews the dashboard at 10 am. What do you do?
Check the refresh history error first: expired credentials, gateway offline, source schema change or timeout. Fix the quick cause and trigger a manual refresh. If it cannot be fixed in time, inform the stakeholders early, state the last refreshed date clearly on the report and share the key numbers from a direct query if needed. Afterwards add refresh failure alerts and a data-as-of label so it never surprises anyone.
04
CAC is 1,200 rupees, average monthly revenue per customer is 500 rupees and gross margin is 40 percent. What is the CAC payback period?
Monthly gross profit per customer is 500 times 40 percent, which is 200 rupees. Payback period equals CAC divided by monthly gross profit, so 1,200 divided by 200 gives 6 months. If customers churn on average before 6 months, the business loses money on acquisition. Using revenue instead of gross profit would wrongly suggest 2.4 months, which is why margin must be included.
05
A lender is launching a new personal loan product. What KPIs would you set up?
Cover the full funnel and risk. Acquisition: applications, approval rate, cost per disbursed loan and time to disbursal. Value: disbursed amount, average ticket size and net interest margin. Risk: delinquency rates at 30 and 90 days past due by cohort, and early default rate. Customer: drop-off by application step, complaint rate and repeat borrowing. Track risk by monthly disbursal cohort, because defaults show up months later.
06
Compare Import mode, DirectQuery and Live Connection in Power BI.
Import copies data into the compressed in-memory model, giving the fastest visuals and full DAX, but data is only as fresh as the last refresh and size is limited. DirectQuery sends queries to the source at view time, so data is near real time but visuals are slower and some DAX is restricted. Live Connection points to an existing published semantic model or Analysis Services model without its own model. Composite models mix Import and DirectQuery.
07
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.
08
What is the difference between a report and a dashboard in Power BI Service?
A report is a multi-page, interactive view built in Power BI Desktop from one semantic model, with slicers, drill-through and cross-filtering. A dashboard is a single-page canvas in the Service made of tiles pinned from one or more reports, and is meant for monitoring key numbers at a glance. Dashboards support data alerts on card and KPI tiles, but have limited interactivity; clicking a tile opens the underlying report for detailed exploration.
The cash conversion cycle measures how many days cash is tied up in operations. It equals days inventory outstanding plus days sales outstanding minus days payables outstanding. Example: inventory sits 40 days, customers pay in 30 days and suppliers are paid in 45 days, so the cycle is 40 + 30 - 45 = 25 days. A shorter cycle means less working capital is needed. Some marketplaces have a negative cycle because they collect from customers before paying sellers.
10
Push notifications increased weekly engagement, but app uninstalls also rose. What do you recommend?
Quantify both effects: extra sessions and revenue from notifications versus users lost through uninstalls and notification opt-outs, including their lifetime value. Segment by notification type and frequency to find which ones annoy users. Recommend frequency caps, personalised timing, relevance rules and easy preference settings, then test them with uninstall rate and opt-out rate as guardrails. Short-term engagement should not cost long-term users.
11
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.
12
Stakeholders give conflicting requirements. What do you do?
Clarify the goal behind each request, map them to business objectives, prioritise with MoSCoW, run a joint session, then document the decision and get sign-off.
13
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.
14
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.
Growth came from more value per customer, not more customers. Break revenue into customers times orders per customer times average order value to see which moved. It could be price increases, larger baskets, a shift to premium products or a few large accounts. Then check risks: is new customer acquisition stalling, is churn being masked, and is growth concentrated in a small segment that could leave?
Log the change, assess impact on scope, cost and timeline, get approval through change control or backlog grooming, and update documents and stakeholders.
A language for querying databases. BAs use it to pull data themselves, validate numbers, check reports and answer questions without waiting for engineers.
19
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.
20
What is the answer-first or pyramid principle approach to presenting analysis?
Start with the main conclusion or recommendation, then give the two or three supporting reasons, and only then the detailed data. Senior stakeholders have little time, so a summary like 'Churn rose because of payment failures; fixing retries can save 4 lakh a month' should come first. Detail goes in the appendix. It is the opposite of a chronological walk through every step of the analysis.
21
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.
22
What is Customer Acquisition Cost (CAC) and what is CAC payback period?
CAC is total sales and marketing spend in a period divided by new customers acquired in that period. If you spend 10 lakh and gain 2,000 customers, CAC is 500 rupees. CAC payback period is how many months of gross profit from a customer it takes to recover that CAC. A shorter payback means the business can reinvest faster; many subscription businesses aim for under 12 months.
SUMIFS is faster and easier for sums with AND conditions on ranges. SUMPRODUCT multiplies arrays and sums the result, so it handles cases SUMIFS cannot: weighted totals like price times quantity, OR logic, conditions on calculated values such as MONTH(date)=4, or comparing two columns row by row. On very large sheets SUMPRODUCT is slower, so prefer SUMIFS or a helper column when possible.
It means making sure stakeholders know realistically what will be delivered, when, and with what limits, before they form their own assumptions. A BA confirms scope in writing, states assumptions and dependencies, shares estimates with ranges, and flags risks early. When something changes, they update stakeholders immediately with options. Most stakeholder conflict comes from surprises, not from bad news itself.
26
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.
27
A mid-size manufacturer must choose between building and buying a warehouse management system. How do you advise?
Compare options on fit, cost, time and risk. Buying a proven product is faster with lower risk and includes upgrades, but may need process changes and has recurring licence fees. Building fits unique processes exactly but needs a strong tech team, longer time and ongoing maintenance. Estimate five-year total cost of ownership, check whether processes are truly unique, and usually recommend buying and configuring unless warehousing is a core differentiator.
28
What do interviewers evaluate in a business case interview?
They assess how you think, not just the final answer. Key areas are clarifying the problem before solving, building a clear and MECE structure, handling numbers accurately with sanity checks, using business sense to prioritise, adapting to new information, and ending with a crisp recommendation with risks and next steps. Thinking aloud and communicating clearly matter as much as getting the right number.
The total profit expected from a customer over the relationship, roughly average margin x purchase frequency x lifespan, compared with acquisition cost.
30
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;
Read the execution plan to find full scans and expensive joins. Filter early on partitioned or indexed columns such as date, select only needed columns instead of SELECT *, and avoid functions on filter columns. Pre-aggregate in a CTE before joining, replace correlated subqueries with joins or window functions, and check join keys have matching types. For repeated use, build a summary table or materialised view refreshed daily.
33
A business head wants 25 charts on one dashboard page. How do you respond?
Ask what decisions they make weekly and which three to five KPIs drive them. Propose a summary page with those KPIs, trends and one breakdown, then drill-through or separate pages for detail. Show a quick mock-up of both versions so they see the clutter and the load time. Use bookmarks or a field parameter to let them switch views without adding charts. Agree on the layout before building.
34
How do you validate that a report's numbers are correct?
Costs: software 12 lakh in year 1 plus 3 lakh per year support, and 4 lakh for implementation and training. Benefits: 60,000 invoices a year at 10 minutes saved each is 10,000 hours; at 400 rupees per hour that is 40 lakh, plus around 5 lakh from fewer late-payment penalties. Year-1 net benefit is 45 - 16 = 29 lakh and payback is under six months. Then test sensitivity, for example if only half the time saving is realised.
36
What is a boundary event in BPMN, and how do interrupting and non-interrupting boundary events differ?
A boundary event is attached to the edge of an activity and reacts to something that happens while that activity is running. An interrupting boundary event (solid double border) cancels the activity and takes the exception path, for example a 24-hour timeout cancelling manual approval. A non-interrupting one (dashed border) starts a parallel path while the activity continues, for example sending a reminder email after 12 hours without stopping the approval task.
37
What is AS-IS and TO-BE process modelling, and where does BPMN fit in?
AS-IS modelling documents how a process works today, including pain points, delays and handoffs. TO-BE modelling shows the improved future process after changes or a new system. Comparing the two reveals the gaps and requirements. BPMN, Business Process Model and Notation, is the standard notation, using events, tasks, gateways for decisions and swimlanes for roles, so both business and IT read the diagrams the same way.
38
Tell me about a time you found an error in a spreadsheet just before it went to management.
Situation: an hour before a quarterly review I noticed regional totals were higher than the company total. Task: find the issue without delaying the meeting. Action: I traced it to a SUMIFS range that stopped at row 5000 while new data went beyond it, plus one duplicated region. I fixed both, converted the data to an Excel Table, and added a check cell comparing totals. Result: the correct deck went out on time and the check became part of our template.
39
The totals in your Excel report differ from the finance system by a few rupees. What could cause this?
Usually rounding. Excel may display rounded values while summing the full-precision numbers, or line items were rounded individually in the source system and the total was computed differently. Check whether finance rounds each invoice line before summing, and apply ROUND at the same level in Excel. Other causes include floating-point artifacts, values stored as text being skipped by SUM, or hidden filtered rows. Agree and document one rounding rule with finance.
40
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.
