How to prepare for first online case study interview - Public Sector Consultant

Richard asked on Aug 27, 2018 - 1 answer

Hi all,

I have been invited to undertake an online case study for a Public Sector Consultant role in the Middle East. Whilst I have significant professional experience, I have never had to do an online case study as part of a recruitment process (nor have I held a specific consultancy role before). As such, I was wondering if the community might be able to provide some guidance as to what to expect and how to prepare?

In terms of the information I have been given, I have been told the case study will be sent at a specific time, I will have two hours and I will need access to word and power point. The role itself is as a Public Sector Consultant.

Any insight would be hugely appreciated given my lack of experience on this topic.

Many thanks in advance!

It would really help if you can put the name of the company here. Otherwise, it's really hard to help you.

It looks like you are talking about BCG case and you can find a sample here:

The best way to prepare is the following:

  1. Train mental math. I posted the main tips here:
  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: Unfortunately free cases don't have the prep questions.

The appropriate structure for BCG written case is:

Slide 1: Context, Objective, Recommendations

Slide 2-4: Analysis (Usually 1 slide with a table, 1 slide with graphs and 1 slide with pros and cons)

Slide 5: Next steps or risks & mitigation

Good luck!
