02
Gross margin fell from 38 percent to 34 percent in one quarter. How do you investigate?
Show answer
Break the change into drivers. Price: were discounts or promotions deeper? Mix: did sales shift towards lower-margin products, channels or regions? Cost: did raw material, freight or supplier prices rise, or did currency movements raise import costs? Also check one-offs like inventory write-offs and accounting reclassifications. Build a margin bridge showing how many percentage points each driver contributed, then take the biggest driver to the business owner with a specific action.
03
A food delivery company's orders fell 15%. How do you investigate?
Show answer
Check data accuracy, then segment by city, restaurant, time and user type; look at supply, delivery time, pricing, competitors and seasonality before proposing fixes.
04
What is the 80/20 rule in business analysis?
Show answer
Pareto principle: about 80% of outcomes come from 20% of causes, such as most revenue from a few customers or most defects from a few issues.
05
What is the AARRR or pirate metrics framework?
Show answer
AARRR breaks the customer lifecycle into five stages: Acquisition, how users find you; Activation, their first good experience; Retention, whether they come back; Referral, whether they recommend you; and Revenue, whether they pay. Each stage gets one or two metrics, such as sign-ups by channel, activation rate, Day-30 retention, invite rate and conversion to paid. It helps find which stage is the weakest bottleneck.
06
Write Excel formulas to find the second-highest sales value and the name of the rep who achieved it.
Show answer
// second highest value
=LARGE(C2:C100, 2)
// rep name for that value
=INDEX(B2:B100, MATCH(LARGE(C2:C100, 2), C2:C100, 0))
// with ties, SORTBY gives a clean list:
=TAKE(SORTBY(B2:C100, C2:C100, -1), 2)
07
Tell me about a time you misunderstood a requirement. What did you learn?
Show answer
Situation: I was asked for 'monthly active customers' and built it on login data. Task: deliver the report for a review. Action: in the demo, the stakeholder said active meant customers who purchased, not logged in. I owned the mistake, rebuilt the measure in two days and wrote down the definition for sign-off. Result: the report was accepted, and now I always confirm definitions and sample outputs with stakeholders before building anything.
08
The sales team keeps hitting its revenue target, but company margins are falling. What would you recommend?
Show answer
The incentive rewards revenue regardless of profitability, so reps are likely discounting heavily or pushing low-margin products. Analyse deal-level discount, product mix and margin by rep and region to confirm. Then recommend changing the target to gross margin or contribution, or adding discount approval limits and a margin floor to commission. Pilot the new plan with one region and track revenue, margin and win rate together.
09
Write DAX measures for Total Sales, Sales Last Year and Year-over-Year growth percent.
Show answer
Total Sales = SUM(Sales[Amount])
Sales LY =
CALCULATE([Total Sales], SAMEPERIODLASTYEAR('Date'[Date]))
YoY % =
DIVIDE([Total Sales] - [Sales LY], [Sales LY])
-- needs a marked date table; DIVIDE avoids divide-by-zero errors
10
Tell me about a time you mapped a process and discovered a major inefficiency.
Show answer
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.
11
What steps would you follow to create a tracking plan for a new 'save for later' feature?
Show answer
Start from the questions to answer: how many users discover it, use it and later buy saved items. Define events such as save_clicked, saved_item_viewed, saved_item_removed and saved_item_purchased, with properties like product ID, price, source screen and platform. Follow the existing naming convention, assign owners, review with developers, and test events in a staging build. Build the dashboard before launch so data is checked on day one.
12
What are process levels such as L0 to L4 in a process architecture?
Show answer
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.
13
What is a product backlog vs a sprint backlog?
Show answer
The product backlog is the ordered list of all desired work; the sprint backlog is the subset the team commits to in the current sprint.
14
Guesstimate: how many laptops are sold in India each year?
Show answer
Segment by buyer. Households: about 30 crore households, roughly 15 percent own a laptop, so 4.5 crore laptops, replaced every 5 years, gives about 90 lakh a year, plus around 20 lakh first-time student buyers. Businesses: assume 4 crore office workers using laptops, replaced every 4 years, giving 1 crore. Government and education schemes add around 10 lakh. Total is about 2.2 crore. Sanity check against industry trends and give a range of 1.5 to 2.5 crore.
15
How are OKRs different from KPIs?
Show answer
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'.
16
How would you forecast next quarter's sales in Excel?
Show answer
Use FORECAST.ETS or a trendline on monthly history, check seasonality, compare with a simple moving average and present a range, not a single number.
17
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?
Show answer
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.
18
Push notifications increased weekly engagement, but app uninstalls also rose. What do you recommend?
Show answer
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.
19
How do you calculate cycle time, touch time and process efficiency? Give an example.
Show answer
Cycle time (lead time) is the total elapsed time from the start to the end of a case. Touch time is the time someone actually works on it. Process cycle efficiency is touch time divided by cycle time. Example: a refund takes 5 working days (40 working hours) end to end, but the agents spend only 2 hours in total working on it. Efficiency is 2 / 40 = 5 percent, so 95 percent of the time is waiting, and queues are the main target.
20
What is the difference between XLOOKUP and INDEX-MATCH?
Show answer
Both look up values flexibly; XLOOKUP is simpler with built-in not-found handling, while INDEX-MATCH works in older Excel versions.
21
What is the cash conversion cycle?
Show answer
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.
22
How would you size the market for IT courses in Delhi NCR?
Show answer
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.
23
What is the Ansoff matrix and how is it used in growth cases?
Show answer
The Ansoff matrix maps four growth strategies by product and market. Market penetration sells existing products to existing markets, the lowest risk. Product development offers new products to existing customers. Market development takes existing products to new markets, such as new cities. Diversification launches new products in new markets, the highest risk. In a growth case it structures the options before you evaluate each one's size, cost and fit.
24
A company reports a profit every quarter but is running out of cash. How do you explain and investigate it?
Show answer
Profit is an accrual figure, while cash depends on timing. Check working capital first: receivables may be growing because customers pay late, inventory may be piling up, or suppliers may be demanding faster payment. Then look at large capex, loan repayments, and dividends. Review the cash flow statement and compute days sales outstanding and inventory days over time. Fixes include tighter credit terms, collection drives, inventory reduction and renegotiating supplier terms.
25
Write non-functional requirements for an online payment page.
Show answer
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.
26
What is a boundary event in BPMN, and how do interrupting and non-interrupting boundary events differ?
Show answer
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.
27
Tell me about a time you discovered a missed requirement late in a project.
Show answer
Situation: two weeks before go-live of a billing system, a finance user asked how GST credit notes would work, which we had not covered. Task: assess and recover. Action: I analysed the impact with developers, found a simple configuration path for most cases plus a manual step for rare ones, and presented both options with dates to the sponsor. Result: we went live on time with a documented workaround and delivered the full fix next sprint.
28
When would you use SUMPRODUCT instead of SUMIFS?
Show answer
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.
29
Should a supermarket chain launch its own private-label products?
Show answer
Evaluate attractiveness and ability. Attractiveness: private labels usually earn higher margins, so check category size, how price-sensitive customers are, and whether brand loyalty is weak in categories like staples and cleaning. Ability: supplier availability, quality control, shelf space and brand trust. Estimate the margin gain against cannibalisation of branded sales and supplier relationships. Recommend starting with a few high-volume, low-loyalty categories and measuring repeat purchase.
30
What is a cutover plan and a go-live readiness checklist?
Show answer
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.
31
SQL: month-over-month revenue growth.
Show answer
WITH m AS (SELECT month, SUM(amount) AS rev FROM orders GROUP BY month)
SELECT month, rev,
ROUND(100.0 * (rev - LAG(rev) OVER (ORDER BY month))
/ LAG(rev) OVER (ORDER BY month), 1) AS mom_pct
FROM m;
32
What is Power Pivot?
Show answer
An Excel add-in for building data models with relationships and DAX measures over millions of rows, beyond normal worksheet limits.
33
Guesstimate: how many weddings take place in India in a year?
Show answer
Assume a population of about 144 crore and an average life expectancy of about 70 years, so roughly 2 crore people reach a typical marriage age each year. If about 95 percent of them marry at some point, that is around 1.9 crore people, or about 95 lakh weddings, since each wedding involves two people. A reasonable estimate is around 1 crore weddings per year, concentrated in the winter wedding season.
34
Write a UAT test case for logging in to a banking app with OTP.
Show answer
Test case ID: UAT-LOGIN-03. Precondition: registered customer with a verified mobile number. Steps: 1. Open the app and enter the registered mobile number. 2. Tap Send OTP. 3. Enter the 6-digit OTP received by SMS within 3 minutes. 4. Tap Verify. Expected result: the customer lands on the account dashboard, and the login is recorded in the activity log. Related negative cases: wrong OTP shows an error, and three wrong attempts lock login for 30 minutes.
35
Stakeholders give conflicting requirements. What do you do?
Show answer
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.
36
Write a SQL query to get each customer's first order date and first order amount.
Show answer
WITH ordered AS (
SELECT customer_id, order_date, amount,
ROW_NUMBER() OVER (PARTITION BY customer_id
ORDER BY order_date, order_id) AS rn
FROM orders
)
SELECT customer_id, order_date AS first_order_date,
amount AS first_order_amount
FROM ordered
WHERE rn = 1;
37
How do you handle large datasets in Excel?
Show answer
Use tables, Power Query, remove volatile functions, filter before calculating and move to Power Pivot or a database when rows reach the millions.
38
Developers say a requirement is not technically feasible, but the business insists on it. How do you mediate?
Show answer
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.
39
A manager says the dashboard total does not match the finance team's Excel sheet. What do you do?
Show answer
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.
40
Tell me about a time UAT revealed a major issue that earlier testing missed.
Show answer
Situation: a new claims system passed QA, but in UAT a claims officer tried a real scenario with two policies on one claim. Task: as BA I had to assess and resolve it quickly. Action: I confirmed the requirement never covered multi-policy claims, quantified that 8 percent of claims were affected, and agreed a manual workaround while the change was built. Result: we went live on time, delivered the fix in the next release, and I added real case samples to future test design.
