Combination of PEI and case interviews. Be prepared to go into detail with the PEI on just one topic. The case interviews seemed more straightforward than Bain's and BCG's. The PEI was actually quite fun if you care about the topic.
Interview questions [1]
Question 1
Talk about an instance where you helped champion diversity and inclusion?
Straightforward, well structured & well explained. Long duration, with 5 30-ish minute interviews total spread out over the course of a couple of weeks. Great support, information on requirements/evaluations readily available.
Too long - too many rounds. Had to play a game first, then multiple rounds. No follow ups after I was rejected - I got ghosted.
Did not enjoy it - obviously this was a long while back and I was too young to notice but not a good behaviour. Truly no respect.
The process made me feel very unprepared but I was able to get through with all of my studying. I would recommend anyone about to interview with them look at Harvard Business cases as reference
