How to learn to solve estimation questions

Hello folks,

This year I applied for BCG and McKinsey in one of Europe offices. I have interviewed for all the rounds in BCG and McKinsey. For me, the hardest part was answering estimation questions and unfortunately in my 2nd and final round interviews with BCG, I was constantly asked estimation questions (directly or as a part of the business case problem). For instance, in my final decision round interview with BCG, the managing partner asked me "How many people enters to an average bank office?" then as a follow-up he asked "Using the previous question, estimate how many bank offices are there in the whole country?". I had a really hard time approaching these type of questions. Could you please suggest me ways to learn how to approach estimation questions?

Thank you very much!

One of the case prep platforms that offered more insight into not just the interview process but actually creates the experience is "Consulting Confidant:" a case prep platform that sets up mock interviews between candidates and consultants from top firms such as BCG, McKinsey, Deloitte, etc.

The program was tailor made by a BCG alum who knows the ins and outs of consulting recruiting and how the navigate the process from various perspectives. Through the program you can set up calls and practice various case types, even "market sizing" cases as you mentioned that can offer real insight into the process and valuable feedback to refine your approach!

Consulting Confidant even has a YouTube channel with a live market sizing case to offer some insight into the process they use!

Hope this helps!
