They have a simple and yet complex way of hiring people. They will do a telephonic interview with HR at first and then will call you onsite. At onsite, they will arrange for meetings with different teams which have open positions. If any one of the team is interested in you. They will hire you! period. See how simple it seems - but the problem (at least what happened with me(check other people views)) is their HR is very very slow to react (if at all they do). I cracked each and every phase of the interview, the HR called me the very next day after the interview and said that they would like to go ahead and offer the job after a background check for which they need some specific details of mine. I waited for that email (of course i called and emailed) for a month without any result; at last I got hold of HR and asked for the reason of delay , HR replied- "Sorry! we decided not to go ahead with your application and we never got to start your BG check. I am sure I emailed you about this". The second sentence is what made me shocked. The least an interviewer can do is to update the interviewee for their efforts. It seemed very unprofessional for a company which I admire bcoz of their work.
