Start your free caseHow Deloitte runs a case interview
Delivery-minded and implementation-grounded. Wants the operating model, the sequencing, and who owns what at go-live. Pushes from strategy into 'how does this actually get built and run' — scope, timeline, and the org that has to sustain it.
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.

Common questions
- Are these real Deloitte cases?
- No. Cases are written in Deloitte's style by working consultants; they are not Deloitte's own published cases. Where a case adapts a public sample, the case page cites the source.
- Can I practice a Deloitte 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 a Deloitte technology case different from a strategy case?
- Deloitte-style tech cases push from strategy into delivery: the operating model, the sequence, scope and timeline, and who owns the system at go-live.
