01
What is the difference between absolute, relative and mixed cell references in Excel?
A relative reference like A1 shifts when the formula is copied. An absolute reference like $A$1 stays fixed, useful for a tax rate or target cell. A mixed reference fixes only the column ($A1) or only the row (A$1), which is handy in multiplication grids or when copying a formula across months and products. Press F4 to cycle through the four options while editing a formula.
02
Guesstimate: how many laptops are sold in India each year?
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.
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.
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.
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.
Capex (capital expenditure) is spending on long-term assets that benefit several years, such as machinery, buildings or capitalised software development. It goes on the balance sheet and is expensed gradually through depreciation or amortisation. Opex (operating expenditure) covers day-to-day running costs such as salaries, rent and cloud subscriptions, and is expensed in the period it occurs. Moving from owned servers to cloud services shifts IT spending from capex to opex, which changes how budgets and business cases look.

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.
11
Guesstimate: how many weddings take place in India in a year?
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.
A live connection queries the source database every time the view changes, so data is current but speed depends on the database. An extract (.hyper file) is a compressed snapshot stored by Tableau that is fast to query and can be refreshed on a schedule, but it is only as fresh as the last refresh. Extracts suit large, slow or remote sources; live suits fast warehouses and real-time needs.

Tell me about a dashboard you built that changed a business decision.
Situation: regional sales heads reviewed discount spend only at month end. Task: I was asked to give weekly visibility. Action: I built a Power BI report linking discounts to margin by product and region, with a drill-through to deal level and an alert when margin fell below target. Result: the team spotted two regions giving deep discounts on low-margin items, tightened approval rules, and margin improved by about two points the next quarter.
15
Daily active users dropped 10 percent week over week. How do you investigate?
Rule out data issues first: tracking changes, app release bugs, pipeline delays or bot filters. Check whether the drop is seasonal by comparing with the same week last year or a festival calendar. Then segment by platform, app version, country or city, acquisition channel and new versus returning users to locate it. Look at the funnel for the core action. Connect findings to releases, outages or marketing changes, then recommend fixes.
A self join joins a table to itself using two aliases, so you can compare rows within the same table. A classic business example is an employees table with a manager_id column: joining employees e to employees m on e.manager_id = m.employee_id lists each employee with their manager's name. Another example is finding customers who placed two orders on the same day by joining orders to orders on customer_id and date with different order IDs.
EBITDA is earnings before interest, taxes, depreciation and amortisation. It approximates operating profit generated by the core business before financing choices, tax rules and non-cash accounting charges. It is useful for comparing companies with different debt levels or asset ages and is used in valuation multiples such as EV/EBITDA. Its weakness is that it ignores capital expenditure and working capital needs, so a company can show strong EBITDA and still burn cash.
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.
19
After joining orders to a payments table, your total revenue doubled. What went wrong?
The join created a fan-out: some orders have more than one payment row, such as split payments or retries, so each order amount is repeated. Check the grain by counting rows per order_id on both sides. Fix it by aggregating payments to one row per order in a CTE before joining, joining on the full key, or summing from the table whose grain matches the metric. Always compare row counts before and after a join.
20
What do statistical significance and p-value mean in an A/B test?
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.
21
What is a stakeholder and who are the typical stakeholders in a project?
SIPOC stands for Suppliers, Inputs, Process, Outputs and Customers. It is a one-page, high-level table that lists 4 to 7 main process steps along with who supplies what and who receives the outputs. A BA uses it at the start of a process improvement project to agree on scope and boundaries with stakeholders before spending time on a detailed BPMN map. It prevents arguments later about where the process starts and ends.
Scrum works in fixed sprints with defined roles such as product owner and scrum master, planned sprint goals and ceremonies like planning, review and retrospective. Kanban has no sprints: work flows continuously across a board, and work-in-progress limits on each column prevent overload. Kanban measures cycle time and throughput. Scrum suits product development with planned increments; Kanban suits support, operations and reporting requests that arrive unpredictably.
25
Tell me about a time poor or outdated documentation caused a problem. How did you fix it?
Situation: a new developer built a GST calculation from an old FRD version, and the error was caught only in UAT. Task: fix the defect and prevent repeats. Action: I moved all requirement documents into one shared space with version history, added a change log and status labels such as draft or approved, and linked each user story to the latest approved section. Result: in the next two releases we had no defects caused by outdated specifications.
26
What is the difference between a calculated column and a measure in Power BI?
A calculated column is computed row by row at refresh time and stored in the model, so it uses memory and can be used in slicers, rows and relationships. A measure is computed at query time based on the current filters, so it is not stored and responds to slicers. Use a column for attributes such as an age band, and a measure for aggregations such as Total Sales or Margin %.
27
What are start, intermediate and end events in BPMN?
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.
28
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.
29
What is the difference between Power BI Desktop, Power BI Service and Power BI Mobile?
Power BI Desktop is the free Windows app where you connect to data, model it, write DAX and design reports. Power BI Service is the cloud portal where you publish reports, schedule refresh, build dashboards, set permissions and share with users. Power BI Mobile is the phone app for viewing reports on the go. A typical flow is build in Desktop, publish to a Service workspace, and consume on web or mobile.
A data object (page shape with a folded corner) represents information that an activity needs or produces during one process instance, such as an invoice or an application form. It is linked with dotted associations. A data store (cylinder) represents information that persists beyond the process instance, such as the customer database or ERP. Showing them helps developers see which systems are read or updated at each step and helps spot missing integrations.
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.
33
How is a product owner's role different from a business analyst's role?
The product owner owns the product vision and the backlog order, makes final priority decisions and accepts completed work on behalf of the business. The business analyst works on understanding problems in depth: eliciting and analysing requirements, modelling processes and data, writing detailed stories and acceptance criteria and supporting the team and testers. In smaller teams one person may do both, but the PO decides what, while the BA clarifies how it should work.
34
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;
A data dictionary is a catalogue of data elements used in a system or report: field name, business definition, data type, length, allowed values, mandatory or optional, source system, owner and example values. A BA maintains it so business users, developers and testers use one definition, for example what counts as an active customer. It prevents mapping errors in integrations and migrations, speeds up testing and reduces disputes about why reports do not match.
Decide whether and how to enter a market by evaluating attractiveness, competition, capabilities and entry mode (build, buy, partner), then risks and next steps.

Tell me about a time you built a business case for a project. Was it approved?
Situation: our support team handled order-status queries manually, about 9,000 a month. Task: I was asked to evaluate a self-service tracking page. Action: I measured handling time from ticket data, estimated deflection conservatively at 40 percent, worked with IT on build and run costs and showed best, base and worst cases with payback. Result: leadership approved the base case. Six months after launch, deflection reached 46 percent, and I presented the benefits review to the same committee.
Use MoSCoW (Must, Should, Could, Won't), value versus effort scoring or the Kano model, agreed with stakeholders based on business value and risk.
