Fictional practice, not an employer interview question.
Imagine a client wants a rapid automation proposal but different teams disagree on the current cost and error rate. Resist proposing a tool before defining the process boundary and the decision the client needs. Distinguish measured facts, estimates and stakeholder preferences.
Work through the case
Build or write this
Write a two-page recommendation with a process map, a limited discovery plan, options, implementation dependencies and a measurable pilot. Consulting candidates can practice synthesis; technical candidates can demonstrate a bounded integration; assurance-oriented candidates can focus on evidence and review, without offering professional opinions outside their qualifications.
Stress-test the decision
The recommendation should remain useful when a key cost assumption changes. Explain why a smaller pilot may be more credible than an impressive savings estimate built on an unverified baseline.
Turn the exercise into application evidence
Use only your own work, public material or an authorized sandbox. Write the problem, your decision, the test and the limitation in a short case study. A diagram or a focused analysis is acceptable when code is not relevant to the role. Do not claim the exercise reproduces the employer's systems or guarantees an interview.
Prepare your application
For Deloitte, identify the member firm, country and practice before choosing interview preparation. Consulting cases, technical work, audit and tax evidence are not interchangeable. Build a clear account of problem solving, collaboration and quality, and follow the recruiting rules for the specific process.
