Hi,
Bain has a written case, that looks kind of a test. You can find an example here (ask me for a password):
https://www.dropbox.com/sh/zor4m49eyx5qxal/AABeUN6mtiGkWhEklRjszX2Oa?dl=0
Bain Written Case has 2 main parts:
- Case information you have to go through
- Slides with the 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 you'll be able to find in google or in case books. I've seen a couple in "Vault Guide to the Case Interview" and "Insead Business Admission Test"
- Harvard cases - either buy or try to download for free. 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!
