Final Round Market Sizing

I have a final round interview this Friday with Bain, and I was wondering what to do if I am given a Market Sizing case. I've heard that sometimes Partners are less concerned with doing extensive cases and will just give a market sizing question or two. However, I've heard that while Market Sizing cases within other cases should take 5-10 minutes, pure Market Sizing questions should take ~20 minutes. However, I'm curious if I should chalk this scenario up to the Partner being less concerned about a full case and take 10 minutes, or to take double the time.

You should definitely be prepared for a case as well for your final round interview. Every partner has a different style of assessing candidates, some may throw in market sizing but it is not as common as you have read.

In terms of the amount of time - it should be no different to the time it would actually take to solve it. Unless it is a very detailed market sizing question (so more or less like a case) you should treat it as a normal market sizing question and solve it as you would normally.

Best,

Getting such a case in the final round is highly unlikely. However, if iyou should get this as a full case, approach it as any other market sizeing brain teaser. The interviewer would then most likely guide you into a separate, more in-depth discussion on something else to which the market size was just the door opener.

Generaly, you should approach final round interviews just like any other interview as well. Maybe with the twist that there is some likelihood that you'r not being shown charts and data, but the case stays on a more conceptual level.

Hi Anonymous,

Rather unlikely to have such an extended market sizing case - how would that help me to evaluate your skills that much better than a 5 minute market sizing?

Whenever in doubt about how much time to take, just ask your interviewer - it's perfectly fine to clarify expectations and align accordingly!

Hope that helps - if so, please be so kind to give it a thumbs-up with the green upvote button below!

Hi there,

I'd advise you prepare for a normal without giving too much importance about this point. A case is a case, not matter if it lasts 10 or 20 minutes and its most important part is the structure, so make sure you have a good one!

I hope this helps,

Mehdi

Just like the stock market, you cannot predict what is going to happen.

Anything and everything is game.

So, just continue preparing, and prepare yourself to always be ready to react to the unknown!

Any other form of preparation/prediction is wasted here!

Hello!

Congrats for moving to final round!

As it has been outlined, its very similar, but :

  • Cases you can expect are more "free riding" - less organized than the ones your found in the 1st round or most prep pages
  • Stronger emphasis in the FIT part, as outlined before by other coaches.

If you are interested in deepening your knowledge and preparation on the FIT part, the "Integrated FIT guide for MBB" has been recently published in PrepLounge´s shop (https://www.preplounge.com/en/shop/tests-2/integrated-fit-guide-for-mbb-34)

It provides an end-to-end preparation for all three MBB interviews, tackling each firms particularities and combining key concepts review and a hands-on methodology. Following the book, the candidate will prepare his/her stories by practicing with over 50 real questions and leveraging special frameworks and worksheets that guide step-by-step, developed by the author and her experience as a Master in Management professor and coach. Finally, as further guidance, the guide encompasses over 20 examples from real candidates.

Furthermore, you can find 3 free cases in the PrepL case regarding FIT preparation:

- Intro and CV questions > https://www.preplounge.com/en/management-consulting-cases/fit-interview/intermediate/introduction-and-cv-questions-fit-interview-preparation-200

- Motivational questions > https://www.preplounge.com/en/management-consulting-cases/fit-interview/intermediate/motivational-questions-fit-interview-preparation-201

- Behavioural questions (ENTREPRENEURIAL DRIVE) >https://www.preplounge.com/en/management-consulting-cases/fit-interview/intermediate/behavioral-questions-entrepreneurial-drive-fit-interview-preparation-211

Feel free to PM me for disccount codes for the Integrated FIT Guide, since we still have some left from the launch!
