I applied through an employee referral. The process took 8 weeks. I interviewed at Google (Sunnyvale, CA) in Mar 2018
Interview
Applied through an Employee referral and got an email from the recruiter indicating a phone interview by a TPM. I got a call back the next day regarding an onsite interview.
4 onsite interviews (2 technical and 2 non-technical). Standard PM related questions and system design questions for technical. Currently waiting to hear back about the decision.
