case interviews
Consulting cases across common categories.
Each run walks the real interview arc — stem, clarifiers, framework, data rounds with a so-what, then an answer-first recommendation. The arithmetic is exactly the kind the techniques on this site are built for.
Pick a case type
Profitability decline
lvl 1Profit = Revenue − Cost
Break a shrinking profit into price, volume and cost, then find the segment dragging the average down.
Run a case →Market sizing
lvl 1Population → households → units → $
Build a defensible top-down estimate out loud, then sanity-check it per person.
Run a case →Market / product entry
lvl 2Attractive? Can we win? Worth it?
Size the prize, run the unit economics, and test breakeven and payback.
Run a case →Pricing move
lvl 2Δ price vs. Δ volume
Trade a price increase against elasticity using contribution margin, not revenue.
Run a case →M&A / private equity
lvl 3Multiple, synergies, payback
Value a target off EBITDA, add synergies as a perpetuity, and find the real entry multiple.
Run a case →Growth strategy
lvl 2Rank the levers on profit
Compare three growth levers on incremental profit rather than incremental revenue.
Run a case →Operations & cost
lvl 2Capacity, utilisation, unit cost
Find the idle capacity behind a rising unit cost and put a number on recovering it.
Run a case →Chart interpretation
lvl 1Read it, compute it, so-what it
Turn a two-year segment exhibit into growth, share and contribution to growth.
Run a case →TMT: telecom, tech & media
lvl 3ARPU, churn, LTV/CAC, capex payback
Sector cases of TMT: subscriber economics, churn treadmill, and whether a network or content build pays back.
Run a case →Valuation: DCF & multiples
lvl 3CAPM → WACC → EV → equity
Put the finance models to work: build a discount rate from CAPM, value the cash flows as a perpetuity, bridge EV to equity, and cross-check against comparable multiples.
Run a case →Data & analytics
lvl 3Lift, standard error, regression
A statistics case: judge whether an A/B test result is signal or noise, size it in money, and stress-test the regression behind next year's plan.
Run a case →Organisational diagnosis
lvl 3Why the transformation did not land
A post-mortem case: trace promised savings to the P&L, find the leakage, and name the incentive and decision-rights failure behind it.
