The first interview was a 30-45 min case interview. If you get through that you will then be invited to Powerday which is a 3 hour back to back interview with behavioral, job fit, and case interview. It was not too difficult, it was a very smooth process.

Had a first round case interview, after the case you go to a super day in the office to meet in person and complete a soft and case interview they then send offers based on your successful completion

Had a first-round interview with an employee. It is a case study, they will ask you about a specific business or industry and introduce a case study. It should not be hard, write down all the info and make sure to go back and discuss the main points and do not be afraid to ask for some guidance or what they said. It is slightly collaborative, I got an answer wrong, and he told me to approach it differently. it is a profit/loss and breakeven case. So if you have no idea what to do. It has to be one of them. Think out loud as well.
