The interview process is very well organized as you would expect with this kind of company. There are 3 rounds of interviews, 2 interviews per round. Contrarily to McKinsey they can sometimes make an arrangement so that you don't necessarily have to go at the office on a friday.
I found the cases easier than at McKinsey. Revising basic business and proft frameworks was more helpful as they perfectly applied.
The cases are rather interviewee led type of cases although I got interupted to analyse some figures for the "math" questions.
Interview questions [1]
Question 1
I was asked a brain teaser at the end of the interview: you have a cube of 10*10*10 little cubes. How many cubes are left after you remove all the cubes on the edge.
2 cases for R1. Pretty straightforward cases about revenue optimization opportunities. There was a little bit of market sizing but all data needed was given. No behaviorals asked in round 1 for me.
