Does anyone have written case prep material for final round interviews?

Anonymous A

I have a final round interview with AlixPartners, and they have written case interviews. I can't seem to find any good practice written cases online...I've gone through quite a few excellent threads here on PrepLounge, but it would also be great to have some practice resources. Thanks!

Hi,

Here I've uploaded some written case samples here:

The best way to prepare is the following:

  1. Prepare for a regular case interview - it helps a lot. Basically, prep lounge website is about it
  2. Practice reading cases fast and prioritizing the information. I found useful two 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 find online. You can find a couple of MIT cases here for free: https://mitsloan.mit.edu/LearningEdge/Pages/Case-Studies.aspx Unfortunately free cases don't have the prep questions.

Check if the calculator is allowed. So far it was. If not - you have to train mental math. Basically, you need to develop 3 calculation skills:

1) Learn how to multiply double digit numbers (google fast math tips or The Veda math).

2) Learn how to work with zeros. Best way - always use 10^power instead of zeros

Example:

300x9000 = 3*10ˆ2 x 9*10ˆ3=3x9*10ˆ(2+3)=27*10ˆ5

Handwritten it looks not that complicated. If you get used to writing all the numbers that way, you will never loose zeros and all multiplications/divisions will be replaced with + or -.

3) learn the division table up to 1/11 (i.e. 5/6 = 83.3%). It will help you calculate any percentage problems

4) Use math tools (Mimir math for iOS, Math tool on Viktor Cheng website) to practice. Train, train, and train again

Good luck!
