Business Analytics Interview Questions for Principal Roles (₹25–30 LPA)

As a customer, I want to reset my password by email so that I can get back into my account. Acceptance criteria: • Reset link expires in 15 minutes • Password rules are shown while typing • A success message appears after reset

Get distinct user-month pairs, self-join or use LAG on month per user, and keep rows where the previous month is exactly one month earlier.

An Excel add-in for building data models with relationships and DAX measures over millions of rows, beyond normal worksheet limits.

Interviews, workshops, surveys, observation, document analysis, prototyping and brainstorming, chosen according to stakeholders and project stage.

Check market size (population, online ordering share), competition, restaurant supply, unit economics per order, CAC and payback period. Propose a pilot with clear success metrics.

It returns a custom value when a formula errors out, keeping reports clean, for example =IFERROR(VLOOKUP(...), "Not found").

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.

OLTP handles many small day-to-day transactions; OLAP supports analysis over large historical data with aggregates and reporting.

Strengths and Weaknesses are internal; Opportunities and Threats are external. Example: S = strong faculty, W = low brand awareness, O = AI upskilling demand, T = free online content.

An early assessment of whether a proposed solution is technically, economically, operationally and legally viable before committing budget.

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.

A table assigning Responsible, Accountable, Consulted and Informed roles per task so ownership is clear.

Structure it: households × car-owning share ÷ replacement cycle + first-time buyers + commercial fleet. State each assumption clearly and sanity-check the final number.

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.

VLOOKUP or XLOOKUP, INDEX-MATCH, SUMIFS, COUNTIFS, IF, text functions, PivotTables and charts.

A framework listing internal Strengths and Weaknesses and external Opportunities and Threats to assess a project or business position.

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.

A named temporary result introduced with WITH that makes long queries readable and reusable in the same statement.

XLOOKUP can look left or right, uses exact match by default, returns a custom value if nothing is found and doesn't break when columns move. VLOOKUP only looks right and needs a column number.

Reconcile totals with source tables using SQL, check filters and joins for duplication, compare with prior periods and verify with business owners.

Combine cost-plus, competitor benchmarks and willingness to pay from research, test tiers with experiments and check margin and churn impact.

Use historical data with FORECAST.ETS or trend lines, state assumptions, compare against actuals and show best, base and worst scenarios.

A language for querying databases. BAs use it to pull data themselves, validate numbers, check reports and answer questions without waiting for engineers.

Assess market size and demand, customer need, competition, unit economics, capabilities, risks and strategic fit, then test with a pilot before scale-up.

Define churn, analyse who leaves and why, segment customers, find drivers through data and surveys, design retention offers and measure uplift with a control group.

Clarify the underlying goals, present data and trade-offs, facilitate a joint session, escalate to the sponsor if needed and document the agreed decision.

They help the Product Owner refine the backlog, write stories and acceptance criteria, clarify details with developers and support testing and demos.

The sales volume where total revenue equals total cost. It equals fixed cost divided by contribution margin per unit.

Compare the current state (as-is) with the desired state (to-be), list the gaps in process, people or technology, and plan actions to close them.

Separate inputs, calculations and outputs, link all formulas to input cells, add scenarios and checks, and avoid hard-coded numbers inside formulas.

Product, Price, Place and Promotion, the levers a business uses to bring an offering to market.

Waterfall runs fixed phases one after another with requirements frozen early. Agile delivers in short sprints with continuous feedback, so requirements can change. In Agile, BAs maintain the backlog and user stories.

A what-if tool that recalculates a formula for different inputs, for example loan payments across different rates and tenures.

Functional requirements describe what the system does (login, reports); non-functional ones describe how well it does it (speed, security, availability, usability).

Goal Seek (find the input for a target output), Data Tables (see outputs for many inputs) and Scenario Manager (save best, base and worst cases).

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.

Use tables, Power Query, remove volatile functions, filter before calculating and move to Power Pivot or a database when rows reach the millions.

CAGR = (End value / Start value)^(1/years) - 1, entered as =(B2/A2)^(1/n)-1.

Review > Protect Sheet or Workbook with a password, lock cells, hide formulas and allow only selected cells to be edited.

Clarify the scope, break the problem into logical parts, state assumptions with round numbers, compute step by step and sanity-check the 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;

COUNT(*) counts all rows; COUNT(column) counts only rows where that column is not NULL.

Define named scenarios such as best, base and worst with different input values and compare the outputs in a summary report.

Prepare clean data, build PivotTables and PivotCharts, add KPI cards and slicers, and arrange everything on one sheet with a clear layout.

Both look up values flexibly; XLOOKUP is simpler with built-in not-found handling, while INDEX-MATCH works in older Excel versions.

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.

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.

A measurable value showing progress to a goal, such as conversion rate, average order value, cart abandonment rate and customer retention.

Excel suits small to medium data and quick ad-hoc work; SQL queries large databases directly and repeatably.

A model classifying features as basic, performance or delight attributes based on how they affect customer satisfaction, helping decide what to build first.

Functions that summarise rows into a value, such as COUNT, SUM, AVG, MIN and MAX.

Decide whether and how to enter a market by evaluating attractiveness, competition, capabilities and entry mode (build, buy, partner), then risks and next steps.
