HARD Market Sizing Example + Breakdown - Ex-Bain Consultant Interviews ex-McKinsey

If you want to learn how to solve any market sizing, estimation, or guesstimate case like a top 1% candidate, check out our FREE course, Case Interview Fundamentals at https://www.craftingcases.com/freecourse. Module 2 is all about Estimations and Market Sizings, and I'll teach you a step-by-step method to solve any estimation case. You'll also find three FREE cases for high-quality practice, with in-depth answers and comprehensive explanations of the thought process behind these answers. The market sizing in this video is an intermediate difficulty one. You should NOT expect anything easier than this in a Bain or BCG first round, and definitely not in an MBB final round. Bruno and I would frequently use this case when coaching candidates for their case interviews. Most candidates would not be able to solve this estimation case in a real Bain, McKinsey or BCG interview, simply because they don't have the right techniques for the task. What you'll see in this video is that a case with this level of complexity requires diligent top-down structurring, which is exactly what Bruno does - and why he can perform well. Keep watching all the way to my breakdown to understand what top-down structuring is and how you can use it too in your own market sizing cases. Simple market sizings can be intuitive. Interview-level market sizings never are. You'll learn skills and practice to make sure you can solve any market sizing case our there.
