I applied online. The process took 2 weeks. I interviewed at Google in Dec 2011
Interview
Applied online for the position and one week later got an email from a recruiter asking for some more background information. Interview was scheduled for next week with a product manager.
Interview consisted of an estimation problem and some behavioral question.
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.
