Inside the lesson

One prompt, two candidates

A revenue problem at a coffee chain. Both candidates hear exactly the same prompt, and the lesson replays how each of them opens.

Candidate A: the generic opener

A textbook framework, named out loud, not tailored to the question. The lesson breaks down why the interviewer's mental score is already a 4 out of 10.

Candidate B: the diagnostic opener

A tailored split, a hypothesis tied to a real market trend, and permission to dig in. The same 90 seconds, and the interviewer is engaged.

The 90-second checklist

A side-by-side comparison of the two openers, then a five-question checklist you can reuse at the start of any case.

What you will learn

The three things interviewers actually judge in your first 90 seconds: clarity, whether your buckets overlap, and tailoring.
Why naming a framework out loud works against you, and what to say instead.
How to open with a hypothesis instead of a template.
A five-question checklist to run through before you present any structure.
