A. Core BA Mindset & Problem-Solving
What does a Business Analyst do?
Translates business goals into clear requirements, aligns stakeholders, validates solutions with data, and measures impact via KPIs. A BA reduces ambiguity, prioritizes value, and ensures delivery teams build the right thing, not just build things right.
How do you approach an ambiguous problem?
Clarify the outcome first, list assumptions, map stakeholders, gather quick data (10–20% for 80% clarity), propose 2–3 options with trade-offs, pick the smallest experiment/MVP, define success metrics, and iterate.
What’s the difference between a requirement and a solution?
A requirement states what outcome we need (e.g., “reduce checkout drop-off by 15%”). A solution is how we might do it (e.g., “enable guest checkout”). BAs keep them separate to avoid premature design.
How do you prioritize requirements?
Use MoSCoW (Must/Should/Could/Won’t), RICE (Reach, Impact, Confidence, Effort), or simple value vs. effort matrix. Align priorities with OKRs and dependencies; validate with data (e.g., impact from funnel analytics).
What is an MVP?
The smallest product slice that delivers measurable value and learning. Example: launch “Apply coupon” on web only, measure attach rate, then scale to app if ROI is proven.
How do you handle conflicting stakeholder requests?
Clarify the shared goal/KPI, quantify impact and effort, visualize trade-offs, and facilitate a decision using objective criteria (e.g., RICE). Document the decision and revisit after a fixed review window.
What is a business case? What must it include?
Problem statement, options, costs/benefits (quantified), risks/mitigations, assumptions, and ROI timeline. Include a measurement plan (baseline, target, timeframe) and exit criteria.
Give a structured way to define success for a feature.
North-star metric (e.g., conversion), guardrails (NPS, refund rate), target (e.g., +3pp in 8 weeks), and leading indicators (CTR, time to complete). Add success threshold and “kill” criteria.
How do you decide build vs. buy?
Compare TCO (license + integration + maintenance), time-to-value, strategic differentiation, vendor roadmap, and security/compliance fit. Pilot quickly; decide based on ROI and flexibility.
What is a KPI vs a metric?
A KPI is a metric tied to a business objective. “Sessions” is a metric; “Checkout completion rate” can be a KPI if tied to quarterly revenue OKR.
B. Requirements, Agile & Delivery
What are good user stories?
“As a [user], I want [capability] so that [benefit].” Add acceptance criteria, edge cases, and data/telemetry needs. Keep stories INVEST: Independent, Negotiable, Valuable, Estimable, Small, Testable.
Acceptance criteria vs. definition of done?
Acceptance criteria validate story functionality; DoD covers overall quality gates (tests passed, telemetry added, docs updated, accessibility checks done).
How do you run backlog refinement well?
Batch similar items, clarify scope/ACs, split large stories, attach designs/data notes, and estimate with devs. Track open questions and dependencies visibly (e.g., Jira links).
Agile vs. Waterfall: when to use which?
Agile for iterative learning/uncertainty (product features). Waterfall for well-known, regulated, or sequential work (data center migration). Many teams blend: discovery Agile, rollout Waterfall.
What is a sprint goal? Why important?
A single, outcome-oriented statement guiding the sprint (e.g., “validate new pricing page reduces drop-off”). It creates focus and helps trade-offs mid-sprint.
How do you prevent scope creep?
Lock sprint scope; channel new asks into the backlog; use change impact analysis; communicate trade-offs. Document decisions in the ticket.
How do you write non-functional requirements (NFRs)?
Quantify: performance (p95 < 2s), availability (99.9%), accessibility (WCAG 2.1 AA), privacy (data minimization), observability (events logged). NFRs must be testable.
What is a dependency map?
A visual of tasks/teams/systems your delivery relies on. Use it to sequence work, flag risks early, and align timelines across squads.
What documents does a BA typically create?
Problem brief, BRD/PRD, user stories/ACs, process maps (AS-IS/TO-BE), data dictionary, reporting spec, test scenarios, and change log.
Best way to hand off to QA?
Share ACs, edge cases, test data, tracking plan, and mocks. Walk through business rules and success metrics; agree on acceptance evidence.
C. Data Literacy (SQL/Excel/BI) for BAs
What SQL do BAs most often use?
SELECT, WHERE, GROUP BY, HAVING, JOINs, CASE, window functions (ROW_NUMBER, SUM OVER), and date functions. Example: funnel conversion by channel, last-touch source, top products by margin.
Example: Find top 3 products by revenue per category (SQL).

How do you check data quality quickly?
Row counts vs. source, null rates, distinct counts, outliers, key duplication, and freshness. Compare with a known report; reconcile differences before analysis.
Excel tricks every BA should know?
PivotTables, slicers, Power Query (ETL), XLOOKUP (replaces VLOOKUP), dynamic arrays (FILTER/UNIQUE/SORT), TEXTSPLIT, and LAMBDA for reusable formulas. These speed ad-hoc analysis.
What’s a good tracking plan?
Defines events, properties, user IDs, session logic, and joins to reference tables. Includes naming conventions and QA steps. Ensures data is trustworthy and analyzable.
What changed with Google Analytics recently?
GA4 replaced Universal Analytics (July 2023). Event-based model, cross-platform tracking, BigQuery export standard, privacy controls. BAs should know GA4’s event parameters and attribution differences.
Power BI/Tableau: what does a BA need to prove?
Clean data model (star schema), meaningful KPIs, drill-downs, filters, and performance (avoiding row-level calcs where possible). Explain business insight, not just charts.
What is a star schema and why use it?
Facts (transactions) linked to dimensions (date, product, customer). Simplifies joins, speeds queries, and keeps measures consistent across reports.
How do you avoid reporting contradictions?
Define a single source of truth (metrics layer/semantic model), centralize metric definitions, version reports, and add data certification labels.
What is a metric layer/semantic model?
A governed place where KPIs are defined once (logic, filters, grain) and reused across dashboards. Reduces “two sources, two numbers” issues.
D. Analytics, Experiments & Product Sense
Difference between correlation and causation in business?
Correlation shows association; causation means change in X drives change in Y. Use A/B tests, natural experiments, or strong causal logic before claiming impact.
How would you design an A/B test?
Define hypothesis/KPI, pick population, randomize, compute sample size/power, set duration (cover a full cycle), monitor guardrails, analyze significance and lift, and perform a post-launch holdback when needed.
What if experiment can’t run (legal/traffic limits)?
Use pre-post with matched control, diff-in-diff, or staged rollout with synthetic controls. Acknowledge limitations and triangulate.
Name common e-commerce KPIs.
Sessions, add-to-cart rate, checkout completion, AOV, conversion rate, repeat purchase rate, CAC, ROAS, return/refund rate, and NPS/CSAT.
How to improve checkout conversion—BA approach?
Map funnel drop-offs, analyze device/region cohorts, review errors/latency, test guest checkout, simplify forms and payment options, and validate with A/B tests and qualitative feedback.
Define churn for a subscription product.
Customers who fail to renew within grace period. Track gross churn, net revenue retention, and cohorts. Include involuntary churn (payment failures) and retry logic.
Leading vs lagging indicators—examples.
Leading: trial activations, first-week usage, feature adoption. Lagging: revenue, retention after 90 days. Use leading indicators for early risk detection.
How do you size impact quickly (back-of-envelope)?
Opportunity sizing: Reach × Baseline rate × Expected lift × Value per unit. Example: 1M users × 20% visit × +2pp conversion × ₹500/order.
What is cohort analysis and why useful?
Group users by common start (signup/purchase month) and measure retention/spend over time. Reveals whether new users are improving vs. historical cohorts.
North-star metric vs input metrics—example.
North-star: Weekly Active Buyers. Inputs: visits, product views per session, cart adds, payment success rate. Optimize inputs that best predict the north-star.
E. Processes, Communication & Change
How do you run stakeholder interviews?
Prepare objective, open questions, ask “why” 5 times, confirm constraints, and end with “what does success look like?”. Summarize back for alignment.
What is RACI?
Responsible, Accountable, Consulted, Informed. Clarifies roles in decisions—reduces delays and rework.
How do you manage change requests late in a sprint?
Log the request, assess impact, offer trade-offs (swap stories or move to next sprint), and keep decision + rationale visible.
How do you communicate a data-driven recommendation?
State the problem, show the “one-slide” insight (chart/table), list 2–3 options with impact/effort, recommend one, and define the next step/owner/date.
Give an example of a process map and its value.
AS-IS returns flow: customer → courier → QC → refund. Reveals delays (QC backlog) and errors (missing reason codes). TO-BE includes scan automation and reason standardization.
How do you measure the impact of a launched feature?
Pre-define KPIs, compare to baseline/controls, check guardrails (support tickets, latency), segment by device/region, and review after a fixed window (e.g., 4–6 weeks).
What is a post-mortem and how do you run one?
A blameless review after failure to capture what happened, why, and actions to prevent recurrence. Include timeline, impact, root causes, and owners for fixes.
What does ‘data governance’ mean for a BA?
Clear ownership, definitions, access controls, data quality SLAs, lineage, and audit trails. Ensures trustworthy metrics and compliance.
What about privacy and regulations a BA should know?
Collect minimum data, purpose-limit, consent where needed, and retention policies. Be aware of GDPR, CCPA, and India’s Digital Personal Data Protection Act, 2023 for consent and processing principles.
How do you demonstrate BA value as a fresher?
Show structured thinking, SQL/Excel/BI fluency, strong documentation (stories/ACs), clear communication, and impact orientation (before/after metrics from projects or internships). Bring a mini-portfolio (dashboards, PRDs, SQL).
Final Tips for 12 LPA BA Interviews
Tie every answer to a business outcome.
Be data-specific (metrics, baselines, targets, timeframes).
Show you can prioritize, de-risk, and measure.
Keep examples concrete: “We improved checkout completion from 41%→46% in 6 weeks via guest checkout + UPI priority.”
