The process included two rounds,
Round 1 was the case study round, where they gave us a case study which was to be solved within an hour. ( It was an elimination round)
Round 2 was the case debrief and managerial round where first 30 mins, i was questioned about my approach while solving the case study and rest of the time was about managerial questions.
During case debreif, various questions on basic maths ( percentage, percentile, mean, mode, median ) were asked.
The managerial round questions were related to my CV, my internship experiences, and various other aspects like some situational questions, puzzles, guesstimate, etc.
