Master Market Sizing
Most candidates do not lose market-sizing points because of arithmetic. They lose them by choosing the wrong approach, making assumptions they cannot defend, or presenting the final number without confidence. In two sessions, you learn how to choose a clear approach quickly, test whether your answer makes sense, and explain your reasoning under pressure. Then we practise with unseen, timed estimates while I interrupt and challenge you — because that is what the real interview will feel like.
What's included
Coaching delivered via live sessions. Every rep is out loud and interrupted at least once. No written practice.
- A way to choose your approach in the first fifteen seconds and commit to it
- Live, timed, interrupted reps rather than worked examples on paper
- The habit of checking what your own number implies before the interviewer does
- A read on where you actually lost points, from someone who scored these for real
