I applied online. I interviewed at Google (Menlo Park, CA) in Feb 2015
Interview
Fit questions mainly. It wasnt hard. But they were looking for someone with a different background. I wouldve thought they would have screened for that beforehand. Be prepared for questions like why should we hire you.
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.
