GLG interview questions

Company seems good so I applied, interview process was quick and I got call for interview within 2 days of application. HR (Mr Samanavaya) who called was impressive as he explained company business model in best manner one can understand GLG and was patient while I asked too many questions and they were answered well. Next round was a online interview(Mr Jatin) which went well he also explained things well and I was asked to submit a case study in 24 hours. I cleared initial rounds and was asked to meet a senior person in Mumbai (prasantha) the round went well too but I received that I am not selected after 4 days of interview. However no particular reason was mentioned.

They will take you out to lunch or coffee before you interview individually with 4-5 others. This is exhausting, be prepared for the mental marathon. They will ask you the same, if not similar questions each round.
