01
Three departments describe the same order process in three different ways during workshops. How do you arrive at the true AS-IS?
Treat each version as a hypothesis. Walk the process physically or observe real cases end to end, and pull a sample of 20 to 30 recent orders from the system to trace what actually happened. Compare timestamps and status changes with each department's story. Then hold a joint session, show the evidence-based map and mark the variants openly. Often all three are partly right because different order types follow different paths, which should be modelled explicitly.
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.
04
What is incremental refresh and when do you need it?
Incremental refresh partitions a large table by date so each refresh reloads only recent data, such as the last 10 days, while older partitions stay stored. You define RangeStart and RangeEnd parameters in Power Query, filter the date column with them, and set the policy for how much history to keep. It is needed when full refreshes of millions of rows take too long or fail, and it reduces load on the source system.
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;
08
Write a SQL query to list customers who have never placed an order.
SELECT c.customer_id, c.name
FROM customers c
LEFT JOIN orders o ON o.customer_id = c.customer_id
WHERE o.order_id IS NULL;
-- alternative
SELECT customer_id, name FROM customers c
WHERE NOT EXISTS (
SELECT 1 FROM orders o WHERE o.customer_id = c.customer_id
);
09
How do you estimate the annual revenue of a coffee shop chain?
It breaks a top metric into drivers: Revenue = Users × Conversion × AOV; Users = New + Returning, and so on. It shows which lever to pull and where a drop came from.
11
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.
12
Finance asks you to build a monthly cohort retention table in Excel from raw order data. How do you approach it?
Add a helper column for each customer's first order month using MINIFS on customer ID, and another for the order month. Compute the month index as the difference in months between them. Then build a PivotTable or COUNTIFS grid with cohort month as rows, month index as columns and distinct customers as values. Divide each cell by the month-zero count to get retention percentages and add a colour scale to show decay.
13
What is value stream mapping and how is it different from BPMN?
Value stream mapping is a Lean technique that maps the end-to-end flow of material and information to deliver value to a customer, along with timing data such as process time, wait time and inventory between steps. Its focus is finding waste and calculating lead time. BPMN focuses on precise logic: roles, decisions, events and messages, often detailed enough for automation. Many teams use VSM to find where to improve and BPMN to design the new process.
14
What is normalisation, and why are analytics tables often denormalised?
Normalisation splits data into related tables to remove redundancy and update anomalies, which suits transactional systems that write often. Analytics workloads read far more than they write, so warehouses often denormalise into wide fact and dimension tables or star schemas. That reduces joins, makes queries simpler for analysts and speeds up aggregation, at the cost of extra storage and the need for controlled loading pipelines.
15
Should a supermarket chain launch its own private-label products?
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.
16
What is row-level security in Power BI and how do you set it up?
Row-level security restricts which rows a user can see in the same report. In Desktop you create roles under Manage Roles with a DAX filter, such as 'Region'[Manager Email] = USERPRINCIPALNAME() for dynamic RLS. You test with View as Role, publish, and then map users or groups to roles in the Service. Dynamic RLS with a mapping table scales better than creating one static role per region.
17
Vendor A has a lower licence price, but Vendor B has lower running costs. How do you compare them?
Compare total cost of ownership over the same period, usually 3 to 5 years. Include licence or subscription fees, implementation, data migration, integration, training, internal staff time, infrastructure, support and upgrade costs, and exit costs. Discount the yearly totals to present value if the timing differs. Then weigh the result against non-cost factors such as fit to requirements, scalability and vendor stability. Often the cheaper licence ends up costlier once customisation and support are added.
18
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.
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
21
You receive two customer lists from sales and billing and must reconcile them. How do you do it?
Standardise both first: trim spaces, fix case, convert IDs to the same type and remove duplicates. Use a unique key like customer ID, or a combined key of phone and email if IDs differ. Then use XLOOKUP or COUNTIFS to mark each record as matched, only in sales or only in billing, or a Power Query merge with anti joins. Summarise mismatches by type and share the exception list with both owners.
22
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.
Row context means DAX is evaluating one row at a time, as in a calculated column or inside iterators like SUMX. Filter context is the set of filters coming from slicers, visuals, rows, columns and CALCULATE that decides which rows a measure sees. Row context does not filter other tables by itself; context transition through CALCULATE converts it into filter context. Most wrong-number bugs in DAX come from misunderstanding these two.
24
Your process diagram has grown to 80 shapes on one page and stakeholders say they cannot read it. What do you do?
Restructure it into levels. Create a high-level map with 7 to 10 main steps, then collapse detailed parts into sub-processes with their own diagrams. Move complex decision logic into a decision table rather than chains of gateways. Show the happy path first and handle exceptions in separate views. Use consistent naming in verb-noun form and remove duplicated steps. Finally, test readability by asking a stakeholder to explain the diagram back to you.
25
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.
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
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.
28
Developers say a requirement is not technically feasible, but the business insists on it. How do you mediate?
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.
29
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.
30
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.
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;
32
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.
33
What is the difference between Definition of Ready and Definition of Done?
Definition of Ready is a checklist a story must meet before the team pulls it into a sprint: clear description, acceptance criteria, dependencies identified, designs attached and estimated. Definition of Done is the checklist for calling work complete: coded, reviewed, tested, acceptance criteria passed, documented and deployable. The BA mostly drives readiness, while the whole team owns done. Both reduce rework and arguments at sprint end.
34
Tell me about a time your analysis changed a product decision.
Situation: the team planned to add more filters to the search page to fix low conversion. Task: I was asked to size the opportunity. Action: funnel analysis showed most drop-off happened after users opened a product page with no delivery date shown, not in search. I shared the data with session recordings. Result: the team prioritised showing delivery dates on the product page, conversion rose about 8 percent, and the filter work was deprioritised.
35
Guesstimate: how many pizzas are sold in Mumbai on a weekend?
About 20 million people, roughly 10% order pizza on a weekend, about 1 pizza per 2 people in an order. This gives roughly 1 million pizzas, adjusted for outlets and delivery capacity.
36
The sales team keeps hitting its revenue target, but company margins are falling. What would you recommend?
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.
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.
39
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.
40
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.
