Consulting Case Interview Preparation
Profitability, market entry, market sizing, and M&A cases — structured.
Case interviews test structured problem-solving, quantitative comfort, and business judgement under pressure. Whether it's profitability, market entry, market sizing, or M&A, the winning approach is the same: a clear structure, a hypothesis, and a crisp recommendation. This guide shows you how.
What to Expect
The case
A business problem you solve live with the interviewer — interviewer-led or candidate-led. Expect math, exhibits, and follow-ups.
Structuring & math
You lay out a MECE framework, work through numbers cleanly, and interpret exhibits — accuracy and clarity both count.
Synthesis
You close with a confident, action-oriented recommendation and the key risks — the 'so what', not a summary.
Common Questions & How to Answer
A client's profits are falling. What's driving it?
How to answer: Structure profit = revenue minus cost; break each into volume/price and fixed/variable; isolate the driver with data, then recommend.
Should our client enter the electric-vehicle market?
How to answer: Assess market attractiveness, capability/fit, competition, and economics; give a clear go/no-go with conditions.
How many petrol stations are there in your city?
How to answer: Pick top-down or bottom-up, state assumptions clearly, do clean math, and sanity-check the result.
Should Company A acquire Company B?
How to answer: Evaluate strategic rationale, synergies, valuation, and risks; conclude with a recommendation and the key deal-breaker.
A client's costs rose 20% — what do you do?
How to answer: Split fixed vs variable, find the biggest movers, quantify the impact, and prioritize the highest-ROI levers.
Preparation Tips
Lead with a hypothesis and a MECE structure — never recite a generic framework.
Do math out loud and round sensibly; transparency beats a silent exact answer.
Always end with a recommendation plus a risk or caveat — interviewers want decisiveness.
Practice live cases with a partner; case interviews reward reps and composure.
