The interview playbook

The skills that separate candidates who pass from candidates who don't aren't about frameworks. They're about how you talk, think, and move through a case in real time. This is the manual.

Frameworks get you in the room. Technique keeps you there.

Most prep focuses on what to think about: profitability trees, market sizing formulas, MECE structures. That's necessary but not sufficient. The playbook focuses on the other half: how to open, how to narrate, how to handle the moments where you don't know what to do next. These are the skills interviewers actually score you on.

Four skills that matter.

Pacing

Know how long each phase should take and when you're falling behind.

Communication

Narrate your thinking so the interviewer follows your process and is impressed by it.

Composure

Handle ambiguity, unexpected data, and moments of genuine uncertainty without freezing.

Synthesis

Pull scattered analysis into a sharp recommendation that sounds like a consultant wrote it.

Read in order. Practice out loud.

Each module is a standalone coaching session: read the technique, study the worked examples, then run the self-check against your last real case. Module 01 also has a 90-second timer to practise the opening pause against.

Doing the math without freezing

Mental math in an interview isn't about being a calculator. It's about rounding smart, narrating your logic, and catching mistakes before the interviewer does.

Learn the technique. Then practice it.

The playbook gives you the skills. The cases give you the reps. Combine both and you'll walk into your interview ready.
