Tough but fair series of interviews. Definately what I would expect at this level. Seven interviews with different parts of the team as well as the bar raiser who definately raised the bar. Questions went beyond the role itself to more leadership type questions.

8 rounds. 6 technical, one hr and one behavioral. Couple system design, couple coding and one past experiences round. System design is not too hard but you have to have meaty past experiences to justify the position.
