ZS Associates Business Analytics Associate interview questions

Applied for fall cycle; received off-cycle response ~6 months later. Opened with an initial phone screen with HR, followed by phone interview with a manager and a phone case interview with a consultant. Passed that round and was called in to the main office. Main office round consisted of lunch with an associate, fit interview with a principal, written case interview, demonstration from a current BAA, then a final interview with senior staff. The phone case would have been trivial if I hadn't been nervous and had taken her up on the offer to use Excel. The written case was 40 minutes for 4 questions; they were very surprised I got to the end of the 3rd. I would have finished the whole thing but I got sidetracked. The final interview was a combo of basic fit interview and a case in disguise. I didn't realize it was a case until fairly far in, by which time I was basically screwed.

Written Round conducted by Aspiring Minds(pretty easy question related to Quant(16 in 16 min.),Verbal(25 in 25 min.),LR(14 in 14 min.) and Attention to detail(20 in 16 min.)).After that we had a GD round(My topic was 100 days of modi govt.(which was last days' newspaper headline).After that a half an hour case study followed by its discussion with the concerned manager that was followed by a behavioral interview.After that Shortlisting was done and finally 8 people had HR interview in which general questions were asked.5 out of 8 people made it.
