Deloitte Business Technology Analyst interview questions

It was a campus hiring process through which the interview process was scheduled.The candidates were short-listed on the basis of an aptitude test. We were divided in groups and given 30 minutes for a case study and put up a presentation in front of a panel of three recruiters. Also, for whole of the 30 minutes, one of the recruiters was present in the preparation room and silently observing us. After the presentation short listed candidates were called for an interview, which was nothing but a HR interview.
