How to practice on Bain written case? Anyone has experience with a real one? Tips?

Question

Bain has a written case in 2nd round (20-30 slides, select relevant ones to tell a story); does anyone has experience with it? How to practice on story-telling? What is considered good performance on Bain's written case?

Answer 1

Hi,

Bain Written Case has 2 parts:

Case information you have to go through
Slides with missing info you have to complete

Since each question in a written case has an exact correct answer, the success criteria is the number of questions answered correctly.

The best way to prepare is the following:

Check if the calculator is allowed. If not - you have to train mental math. I posted the main tips here: https://www.preplounge.com/en/consulting-forum/tips-to-do-big-multiplications-in-my-mind-726#a1422
Practice solving the cases - basically preplounge website is about it
Practice reading cases fast and prioritizing the information. You can use 2 sources:

Written cases in the internet (You can find some of them in google or in case books)
Harvard cases - either buy or try to download somehwere in the web. You can find a couple of MIT cases here for free: https://mitsloan.mit.edu/LearningEdge/Pages/Case-Studies.aspx The main problem - these free cases don't have any pre-defined questions.

Good luck!
