02
What is a data table in Excel?
Show answer
A what-if tool that recalculates a formula for different inputs, for example loan payments across different rates and tenures.
03
What is the difference between revenue and profit?
Show answer
Revenue is total money from sales; profit is what remains after subtracting all costs and expenses.
04
What techniques do you use to elicit requirements?
Show answer
Interviews, workshops, surveys, observation, document analysis, prototyping and brainstorming, chosen according to stakeholders and project stage.
05
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.
06
How would you estimate the market size for an electric scooter in India?
Show answer
Top-down: two-wheeler market x EV share x addressable segment. Bottom-up: target households x adoption rate x price. Compare both for a sanity check.
07
What checklist do you apply to a BPMN diagram before sharing it with stakeholders?
Show answer
Every diagram has clear start and end events and a title with version and owner. Activities use verb-noun names such as Approve invoice. Each gateway is labelled with a question and its outgoing flows with answers. Splits and joins use matching gateway types. Message flows only connect separate pools. No dangling or crossing arrows where avoidable. The happy path reads left to right. Exceptions are handled, and complex rules are referenced to decision tables rather than drawn as gateways.
08
Explain Porter's Five Forces.
Show answer
A model assessing industry attractiveness through supplier power, buyer power, threat of new entrants, threat of substitutes and rivalry among competitors.
09
Write a DAX measure for the product return rate that avoids divide-by-zero errors.
Show answer
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.
10
What is the difference between system testing, SIT and UAT?
Show answer
System testing is done by the QA team to verify that one system works against its functional and non-functional specifications. SIT (system integration testing) checks that connected systems exchange data correctly, such as CRM to billing to payment gateway. UAT (user acceptance testing) is done by business users to confirm the solution supports real business processes and is ready for go-live. UAT asks whether this is fit for our business, not just whether it matches the specification.
11
How would you structure a weekly project status update for stakeholders?
Show answer
Use a short, fixed format. Start with an overall status of green, amber or red and one line explaining it. Then list what was completed this week, what is planned next week, key risks and issues with owners, and decisions needed from stakeholders with dates. Add a link to the detailed tracker. Keep it under one screen, and highlight anything that changed since last week.
12
What is a stakeholder and who are the typical stakeholders in a project?
Show answer
Anyone affected by or influencing the project: sponsors, product owners, end users, developers, testers, operations and customers.
13
What are start, intermediate and end events in BPMN?
Show answer
Events are circles that show something happening. A start event (thin border) triggers the process, such as a form submitted or a timer firing on the first of the month. An intermediate event (double border) happens during the process, such as waiting for a payment message or a 48-hour timer. An end event (thick border) marks where a path finishes and can carry a result such as a message, an error or termination of all paths.
14
What is the difference between OLTP and OLAP systems?
Show answer
OLTP handles many small day-to-day transactions; OLAP supports analysis over large historical data with aggregates and reporting.
15
What is a BRD review and who signs it off?
Show answer
Stakeholders and the sponsor review the Business Requirements Document for completeness and accuracy, and the business owner gives formal sign-off before design begins.
16
What does a Business Analyst do?
Show answer
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.
17
What is A/B testing?
Show answer
A/B testing is a controlled experiment where users are randomly split into a control group that sees the current version and a treatment group that sees a change, such as a new checkout button. You compare a pre-decided primary metric, like conversion rate, between groups. Because assignment is random, a significant difference can be attributed to the change rather than to seasonality, marketing or user mix.
18
A feature launched two months ago is used by only 4 percent of users. What would you do?
Show answer
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.
19
Inventory days rose from 45 to 70 over two quarters. What could be the causes and what would you recommend?
Show answer
Possible causes include falling sales against unchanged purchasing, poor demand forecasts, bulk buying for discounts, slow-moving or obsolete SKUs, or deliberate stock-building ahead of a festive season or expected price rise. Analyse by SKU, warehouse and age bucket to find where stock is stuck. Recommend clearing aged items, adjusting reorder points using recent demand, and reviewing supplier minimum order quantities. Also quantify the cash locked up and the carrying cost to show urgency.
20
A new TO-BE process went live three months ago. How do you prove that the improvement actually worked?
Show answer
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.
21
What is a use case diagram?
Show answer
A UML diagram showing actors and the actions (use cases) they perform with the system, giving a quick view of scope.
22
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.
23
Tell me about a time you handled a difficult stakeholder.
Show answer
Use STAR: Situation, Task, Action, Result. Show that you listened, found the underlying goal, used data to align people and reached a documented decision.
24
What is a user story and what makes it good?
Show answer
A short requirement written as 'As a user, I want X so that Y', backed by acceptance criteria. Good stories follow INVEST: independent, negotiable, valuable, estimable, small and testable.
25
What are TAM, SAM and SOM?
Show answer
TAM, Total Addressable Market, is total demand for the product if every possible customer bought it. SAM, Serviceable Available Market, is the part you can reach with your model, geography and channels. SOM, Serviceable Obtainable Market, is the share you can realistically capture in the next few years given competition. For an online tutoring startup in India, TAM is all school students, SAM those online in target cities, SOM a small share of that.
26
What is the difference between ROW_NUMBER, RANK and DENSE_RANK?
Show answer
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
Which Excel functions do business analysts use daily?
Show answer
VLOOKUP or XLOOKUP, INDEX-MATCH, SUMIFS, COUNTIFS, IF, text functions, PivotTables and charts.
28
What is user story mapping and how does it help plan releases?
Show answer
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.
29
Revenue grew 20 percent this quarter but the number of active customers stayed flat. How do you interpret it?
Show answer
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?
30
How do you analyse variance between budget and actual?
Show answer
Variance = Actual - Budget, shown as amount and percentage, with conditional formatting to flag large gaps and comments on the drivers.
31
What is a process flow and which tools do you use?
Show answer
A diagram of steps, decisions and owners in a process, made using BPMN or flowcharts in tools like Visio, Lucidchart or draw.io.
32
How do you calculate the percentage contribution of each category?
Show answer
SUM(sales) per category divided by SUM(SUM(sales)) OVER () and multiplied by 100 gives each category's share of the total.
33
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.
34
What is the use of the IFERROR function?
Show answer
It returns a custom value when a formula errors out, keeping reports clean, for example =IFERROR(VLOOKUP(...), "Not found").
35
A hospital chain's average patient waiting time has risen from 30 to 50 minutes. How would you approach the case?
Show answer
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.
36
Write an Excel formula to extract the domain from an email address.
Show answer
// Excel 365
=TEXTAFTER(A2, "@")
// any version
=MID(A2, FIND("@", A2) + 1, LEN(A2))
// Flash Fill (Ctrl+E) also works for one-off cleanup
37
What is working capital and why does it matter?
Show answer
Working capital is current assets minus current liabilities, mainly receivables plus inventory minus payables. It is the money tied up in running daily operations. Too little means the company may struggle to pay suppliers and salaries; too much means cash is locked in slow inventory or unpaid customer invoices. Analysts track it because a growing business often needs more working capital, so fast growth can create cash shortages even when the business is profitable.
38
What is a SWOT analysis?
Show answer
A framework listing internal Strengths and Weaknesses and external Opportunities and Threats to assess a project or business position.
39
What do statistical significance and p-value mean in an A/B test?
Show answer
The p-value is the probability of seeing a difference at least as large as observed if the change truly had no effect. If it is below the chosen threshold, often 0.05, the result is called statistically significant. It does not mean there is a 95 percent chance the variant is better, and significance is not the same as business importance. Always report the confidence interval of the lift as well.
40
What is a star schema and why do BI tools prefer it?
Show answer
A star schema has one central fact table holding numeric events (sales, orders) linked to surrounding dimension tables (date, product, customer, region). BI tools prefer it because filters flow cleanly from dimensions to facts, DAX and Tableau calculations stay simple, and compression and query performance improve. A flat single table repeats text values and gets slow, while a snowflake with many chained lookups makes filtering and maintenance harder.
