Ernst & Young case interview practice
Ernst, in the room.
6 Ernst & Young-style technology cases, each run live against an AI interviewer prompted with Ernst & Young's own register, then scored 0–100 on structure, business acumen, quantitative reasoning and communication. Your first case is free.
Start your free caseHow Ernst & Young runs a case interview
Direct. Pragmatic. Senior-led delivery. Spends 60% of the time on architecture defense and 40% on commercial reality — budget, sequencing, who owns what after go-live.
That is the register the interviewer holds for every case on this page: it asks one question at a time, pushes back when you hand-wave, will not summarise your answer for you, and closes with a partner-style scored evaluation that names the strong signals it heard and the red flags it did not.
What is in the bank
6 cases — 2 intermediate, 2 advanced, 1 medium, 1 hard. Typical length 35-45 min or 25-35 min. Topics: Tech Consulting, Strategy, Sustainability / strategy, Growth strategy, Consumer / restructuring, Manufacturing / Operations.
Cases are written in each firm's style, written and reviewed by working consultants; they are not the firms' own published cases.

Common questions
- Are these real EY cases?
- No. Cases are written in EY's style by working consultants; they are not EY's own published cases. Where a case adapts a public sample, the case page cites the source.
- Can I practice an EY technology case for free?
- Yes. The first case runs free with no signup or card. Paid plans are one-time payments for 30 days of access to the full case bank and scored reports.
- How is an EY technology case different from a strategy case?
- The discipline is the same — sizing, drivers, trade-offs, a recommendation — but EY-style tech cases spend more time on architecture defense and commercial reality: budget, sequencing, and who owns the platform after go-live.
