BlackRock Associate interview questions

I got a call from Blackrock through Linkedin. I had 2 telephonic technical rounds. Then I had F2F discussion in there Gurgaon office. There I had 2 technical rounds(One with offshore technical team and one with onshore technical team.). After that I have been told that feedback is positive.Then one F2F interview with offshore director and one more interview with onshore manger. So In total I gave 6 rounds of interviews. After all these discussion, I have been told that feedback is good and HR will give you a call. But nobody called. When I asked them for feedback, they said I am not selected and they have found some other candidate. ... I dont know the reason, when I ask there HR for the exact reason, they didnt reply back.

have couple phone interviews, then an onsite interviews with about 5-6 people; some one on one, some are group interview; most of the questions are job related. Since the job wasn't too technical, most of the questions were easy
