Good experience, nice interviewer, challenging case study which required careful prep. The PEI part is insightful with many follow-up questions from interviewer. Well-prepared cadidates with standardized framework in mind can impress the interviewer

i went through 4 rounds of interviews, 1st and 2nd with EM/AP level interviewers, 3rd with AP/Partner levels, and the final round Partner interview. The structure to all the interviews were the same: PEI -> Case -> QnA. Case interviews can be very unexpected and niche, heavy on structuring and would say slightly less difficult on the maths. Received my offer 2 weeks after my final round interview, for a placement in the upcoming year.
