I applied through college or university. The process took 2 months. I interviewed at Google (Buffalo, NY) in Jun 2011
Interview
Long and extensive process that took my over 2 months to complete. It was extremely competitive and the interviewers made employees perform a number of tasks to test our abilities.
Very self-driven, first of multiple rounds, where I had to take the initiative to arrive at the problem, constraints, approach, solutions, tradeoffs and reasoning behind it in a matter of 30 minutes.
You would have to do a hiring assessment first, then a recruiter screening follows. First round interview with the hiring manager. Majorly product sense and product improvement. The questions were not direct though.
Overall a lot of steps to the interview process. Talked to different people and had opportunities to ask questions. Many different stages which made it a lengthy process overall. Wasn't too bad.
