01
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.
02
An online learning platform finds that only 12 percent of learners complete paid courses. How do you analyse it?
Define completion and see where learners drop: first week, a specific module or before assessments. Segment by course, length, learner background, device and acquisition channel. Look at causes in content difficulty, video length, lack of deadlines, mentor support and job relevance. Recommend tests such as shorter modules, cohort-based deadlines, progress nudges and live doubt sessions, and measure completion and referral impact.
03
Write Excel formulas to find the second-highest sales value and the name of the rep who achieved it.
// 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)
04
How do you calculate the percentage contribution of each category?
WITH daily AS (
SELECT event_date, COUNT(DISTINCT user_id) AS dau
FROM events
WHERE event_date >= '2026-10-01' AND event_date < '2026-11-01'
GROUP BY event_date
),
monthly AS (
SELECT COUNT(DISTINCT user_id) AS mau
FROM events
WHERE event_date >= '2026-10-01' AND event_date < '2026-11-01'
)
SELECT ROUND(AVG(d.dau) * 1.0 / MAX(m.mau), 3) AS stickiness
FROM daily d CROSS JOIN monthly m;
06
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.
07
An A/B test shows a 5 percent higher conversion rate, but revenue per user is lower. Should you ship it?
Not automatically. Find out why: the variant may push cheaper products, bigger discounts or smaller orders, so more people buy but each spends less. Check average order value, margin and long-term metrics like repeat purchase. Decide based on the metric tied to the business goal, usually revenue or contribution per user, which should have been the primary metric or a guardrail. Consider iterating to keep the conversion gain without lowering order value.
08
What is a communication plan in a project and what does it include?
A communication plan defines who needs what information, when, in which format and from whom. It typically lists stakeholders, their information needs, the channel such as status email, standup, steering meeting or dashboard, frequency, owner and escalation path. It prevents both silence and overload, and makes sure decision-makers hear about risks early. A BA usually keeps it updated as stakeholders change.
ROI (return on investment) is the gain from a specific investment divided by its cost and is used to judge projects or campaigns. ROE (return on equity) is net profit divided by shareholders' equity and shows the return to owners; high debt can inflate it. ROCE (return on capital employed) is EBIT divided by equity plus long-term debt and shows how efficiently all long-term capital is used. ROCE is better for comparing companies with different debt levels.
10
Describe a time you recommended delaying a go-live.
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.
11
Tell me about a time you led or mentored a team of analysts.
Situation: I led three junior analysts on a pricing review with a six-week deadline. Task: deliver quality work while developing them. Action: I split the work by workstream, set up short daily check-ins and a shared query library, reviewed their logic rather than rewriting it, and let each present their section to the client. Result: we delivered a week early, two juniors later handled client calls alone, and the review practice became standard in our team.
12
A stakeholder keeps skipping review meetings and then rejects the deliverable at the end. How do you prevent this?
Talk to them one-to-one to understand why they skip, such as timing, relevance or workload. Offer shorter reviews, asynchronous reviews with a clear deadline, or a delegate with decision rights. Record sign-offs at each stage in writing so late changes become formal change requests. Share early drafts and mock-ups, because people react better to something visible. Escalate to the sponsor if the pattern risks the timeline.
13
Because of a tight deadline, the business sponsor wants to skip UAT and go live directly. How do you respond?
Explain the risks in business terms: without UAT, there is no evidence that real processes work, and production defects cost far more to fix and can affect customers and compliance. Offer alternatives: a shortened UAT covering only critical business flows, parallel running with the old system, a phased rollout to one branch or user group, or extended hypercare. If the sponsor still decides to skip it, record the decision and accepted risks formally.
14
What is Average Order Value and how can a business increase it?
Average Order Value is total revenue divided by number of orders. If an online store earns 9 lakh from 1,500 orders, AOV is 600 rupees. Businesses increase it with bundles, cross-sell and upsell recommendations, free delivery above a threshold, volume discounts and premium options. Watch margin and conversion while doing so, because a high free-delivery threshold can raise AOV but reduce the number of orders.
15
Write an Excel formula that labels sales as High (100000 or more), Medium (50000 or more) or Low.
Drive it from vehicles. Assume about 2 crore new two-wheelers are sold a year, each with an average of 1.5 helmets bought (rider plus pillion), giving 3 crore. The existing fleet is around 25 crore vehicles; assume 60 percent are active and each active vehicle replaces one helmet every 3 years: 15 crore / 3 = 5 crore. Total is about 8 crore helmets a year. Sanity check: enforcement varies by state, so give a range of 6 to 9 crore.
17
How do you write a query to find users active in consecutive months?
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;
19
A critical defect is found on the last day of UAT, and the go-live date cannot move. What do you do?
Confirm the impact and reproduce it quickly. Work with development to estimate a fix and its regression effort. Then present options to the business owner with risks: fix and do targeted retesting before go-live, go live with a temporary workaround or manual process, go live with the affected feature switched off, or delay. The decision belongs to the business, documented at the go or no-go meeting. Never hide a critical defect to protect a date.
20
Write a DAX measure for a running total of sales by date.
Log the change, assess impact on scope, cost and timeline, get approval through change control or backlog grooming, and update documents and stakeholders.
22
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.
DMN (Decision Model and Notation) is an OMG standard for modelling business decisions, mainly through decision tables that list input conditions, outputs and a hit policy. BPMN shows the flow of work, while DMN holds the decision logic. Instead of drawing ten nested gateways for loan eligibility, you place one business rule task in BPMN that calls a DMN table. This keeps diagrams clean and lets business users change rules without redrawing the process.
25
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.
26
Your measure shows the same value on every row of a matrix. Why might that happen?
The filter from the row field is not reaching the fact table. Usually there is no relationship between that dimension and the fact, the relationship is inactive, or it filters in the wrong direction. It can also happen when the measure uses ALL or REMOVEFILTERS on that column, or when the row field comes from the fact table of a different grain. Check the model view and test the measure with a simple SUM.
27
Write an Excel formula for the NPV of a project with an initial investment today and five yearly cash inflows.
# B1 = discount rate (for example 12%)
# B2 = initial investment entered as a negative number
# B3:B7 = cash inflows for years 1 to 5
=NPV(B1, B3:B7) + B2
# NPV() assumes the first value comes at the end of year 1,
# so the year-0 investment is added outside the function.
A use case describes the full interaction between an actor and the system (main and alternate flows). A user story is a short statement of need from the user's point of view, refined with acceptance criteria.
29
Write a DAX measure to count distinct active customers in the last 30 days.
Active Customers 30D =
CALCULATE(
DISTINCTCOUNT(Sales[CustomerID]),
DATESINPERIOD('Date'[Date], MAX('Date'[Date]), -30, DAY)
)
-- MAX('Date'[Date]) makes it relative to the date in the current filter
30
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.
A model assessing industry attractiveness through supplier power, buyer power, threat of new entrants, threat of substitutes and rivalry among competitors.
32
Write a SQL query to calculate monthly customer churn rate for a subscription business.
WITH monthly AS (
SELECT DISTINCT customer_id,
DATE_TRUNC('month', billing_date) AS month
FROM subscriptions_billed
)
SELECT
prev.month AS month,
COUNT(prev.customer_id) AS customers_at_start,
COUNT(prev.customer_id) - COUNT(nxt.customer_id) AS churned,
ROUND(100.0 * (COUNT(prev.customer_id) - COUNT(nxt.customer_id))
/ COUNT(prev.customer_id), 2) AS churn_pct
FROM monthly prev
LEFT JOIN monthly nxt
ON nxt.customer_id = prev.customer_id
AND nxt.month = prev.month + INTERVAL '1 month'
GROUP BY prev.month
ORDER BY prev.month;
33
After many sprints, project documentation is out of date and new team members are confused. What do you do?
Identify which documents are actually used: usually a product overview, process maps, business rules, data dictionary and integration details. Update those first rather than everything. Make documentation part of the Definition of Done, so a story is not complete until related docs are updated. Keep living documents in a shared wiki with owners and last-reviewed dates, and archive outdated files clearly. Test the result by having a new joiner use it during onboarding.
34
Tell me about a time UAT revealed a major issue that earlier testing missed.
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.
35
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.
36
A stakeholder asks for a detailed report by tomorrow, but it realistically needs a week. What do you do?
Understand the real need first: what decision is it for and what is the minimum that helps tomorrow? Offer a phased answer, such as a quick directional view with the top three numbers tomorrow, clearly labelled with caveats, and the full validated report in a week. Explain the trade-off between speed and accuracy. Confirm the agreed plan in writing so expectations are clear.
37
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.
38
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.
39
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.
40
How would you prioritise 10 features with a limited budget?
Score them with RICE or value-vs-effort, align with goals, consider dependencies and risks, validate with stakeholders, then use MoSCoW for the release plan.
