ZS Associates Associate interview questions

Well the first round for selection process was a aptitude test and approximately 30 students made it trough, then the next day we were called at the gurgaon office at 6th floor ,where we were called out for the case study, the case study was one on one interaction with the interviewer and there were data interpretation question along with some theory questions . the second round was the behavioural round which was quite easy and they normally ask you 'tell me about a time ' type questions. after this round only 5 students were taken ahead , the last round was with the principal at 4th floor and he would only ask you about the interviews that took place earlier and cv based questions.
