Realistic consulting cases in 5–15 minutes a day, with an interviewer that pushes back on your reasoning.
One repeatable loop
Client, situation and mandate.
Clarify goal, facts, assumptions.
Hypothesis and issue tree.
Pick your angle, read exhibits.
Quant, sizing, judgement.
Evidence, risks, next steps.
Rubric scores and follow-ups.
What a follow-up sounds like
After each answer you submit, the interviewer responds to the substance of your reasoning. Follow-ups are anchored to the item's approved facts — never invented outside the content. Scripted flows are labelled as scripted, and hints stay off in Mock mode.
Interviewer
Our restaurant client has stable revenue but profits have declined by 15%. How would you investigate?
Candidate
I would split profitability into revenue and costs. Since revenue is stable, I would investigate food, labour, rent and other operating costs.
Interviewer · follow-up
Which cost categories would you prioritise, and what data would help you test whether they explain the decline?
Illustrative example from a practice item.
Type an answer and hit Send, or record a voice note and mark it Done. You get a follow-up that engages your reasoning — not just your final number.
Build issue trees, read exhibits and work calculations in short lessons, then apply the skill in the linked practice item.
Six rubric dimensions, two strengths, two priority fixes, and the next exercise worth doing — so every session points somewhere.
Graduated hints, example scoping questions and live coverage — support that helps without handing you the answer.
Hints and benchmarks stay hidden until you submit — the debrief arrives with your scores, strengths and what to practise next.
