Hi,

That's a usual written case exercise. I've uploaded some samples here:

The best way to prepare is the following:

1. 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
2. Prepare for a regular case interview - it helps a lot. Basically, prep lounge website is about it
3. Practice making slides. Look for publically available MBB presentations for reference. Good books are "Pyramid Principle" and "How to make it with charts"
4. 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.

You'll have to create a presentation either on paper or flipboard. The structure can be the following:

Slides 1-2Context, Objective, Recommendations

Slide 2-4: Analysis (Usually 1 slide per analysis / initiative)

Slide 5: Next steps or risks & mitigation
