Hi all,

Does anyone have experience with interviews at Gamma or other analytics-focused practises/ firms regarding types of fit and technical questions, analytics cases, etc.?
I have an interview with them coming up and can't seem to find much material on this.

Happy about any tips on how to prepare!

When I interviewed at GAMMA I got both business case interviews and technical case interviews. Business case interviews are as usual. Technical case interviews have the same structure with fit and Q&A, but includes a more technical case. E.g. our client is a grocery store chain who would like our help developing personalized promotions in their loyalty program. Typically you would then discuss defining the problem, what data you want and have, which models you would use, and how you would validate and test your model. I prepared by imagining problems like this for different companies, as well as by looking at past Kaggle competitions.

You will hace specific assesments (coding, etc.) + business cases with a strong analytics component in them.

For getting better at analytic cases, on top of lots of practice, I would recommend you GMAT exercises.

There are free exams in the internet that you can use for practice (the one of LBS MBA page, Verits prep, as well as some free trials for courses such as the one of The Economist (

Hope it helps!

It's a mix of regular and data science cases. The last ones test the following things:

  • Structuring - similar to consulting cases
  • Hypothesis testing - very different from the consulting cases because you have to provide the hypotheses on the very granular level
  • Finding the particular data - where would you find the data to test your hypothesis? What Tests would you exactly perform?
