I applied though my friend who is currently working there. After about 90 days i got a call from the HR regarding a written test. After the test again there was no communication for about a month. Then then I got an email and call saying that my interview had been scheduled. There were around 7 people for the position. 1st there was 3 case study which was pretty difficult as you only get 30 mins to solve them. Then you have to explain your approach to one of the Staff member. After this there was another interview (resume based), checking your logical reasoning (guesstimates and puzzles). Then a final HR round.

There were 2 Interview Rounds- Technical and HR. Technical Interview basically focusses on Technical qualifications of the candidate as well as proper questioning related to it. HR Round was not so different for me. The interviewer sort of asked same technical questions along with some logical algebraic problems to solve.
