I have not focused a lot of time on classic market sizing questions so far. I'm wondering how much BCG focuses on sizing questions in its cases. From BCG mock cases / online material I have found, there is not a huge emphasis on market sizing. Any thoughts?
Market sizing at BCG
The very simple answer to your question is "YES IT IS VERY IMPORTANT"
You even can face a market sizing question as your overall case interview at any round.
for me, one of my first round cases was a simple market sizing case. Found it quite odd, but it was still hard, as BCG cases are shorter in time and the interview applied some pressure during the calculations.
Don't think it's that common but it can definitely happen.
Hope that helps :)
I would definitely be prepared to answer a market sizing question. It depends by office, but many offices give their interviews pretty much "free reign" over what questions they ask. When I interviewed at BCG roughly 3 years ago, I received a market sizing question in my final round from a senior partner.
In addition to Vlad's distinction of "standalone" or "part of a broader case", I would further distinguish two types of market sizings you should be ready for:
1) Top-down market sizings - e.g. "what is the value of the total hamburger market in the US?" This question you typically target my starting from total population, segmenting, etc..
2) Bottom-up market sizings (common at Bain) - e.g. "what is the revenue of a typical Tennis club in London?". This question you will struggle to approach top-down, so should approach from a capacity and utilisation approach.
Hope this is helpful!
Yes, market sizing is super important. It can be:
- A part of a case
- A standalone case
So you need to prepare accordingly. Feel free to reach out if you need help on that
