I applied through an employee referral. I interviewed at Google
Interview
Was referred by a friend who worked at GOOG as a PM, the recruiter got in touch fairly quickly. Didn't have to go through a phone screen / behavorial interview, and went straight into the phone interview with a PM who asked how I might think about a mobile ad opportunity.
Interview questions [1]
Question 1
asked how I would approach a mobile ad opportunity.
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.
