There were 2 rounds. 1st round was a telephonic interview by hiring manager and 2nd round was at their office in Pune. 2nd round was for a full day- with 4 interviews including 1 case study presentation. 1st round was primarily knowing you and understand what kind of projects one has worked upon. Involves explaining 2 projects in detail. 2nd round at pune office had 4 interviews: past projects+stats, personal/behavioral, cultural fit, case study presentation. I think the first interview was important here and next intervieers form their judgement base on this/ and verify that.

Interview process was easy. They were very friendly,asked few puzzles in starting then some questions from my favorite subjects and why analytics etc. Fifty percent of puzzle were from the net which i already did and few problems were new, they just want to test your IQ, if u answered 80% puzzles correctly then others things became very easy and there is 100% chance u r going to placed. Overall interview was very good and not any difficult question asked by them.
