Google Project Manager interview questions

Phone screen followed by on-site interview. Had four product interviews and one technical interview. Three interviews were by PMs and one was a Group PM. The technical interview was led by an engineer. Questions were fairly standard, how would you improve the in-store shopping experience, what will be the impact of self-driving cars, how many buildings are built in California etc.

I was recruited from the university. First I had a talk with a very nice recruiter. She asked me about my interest, some behavioral questions, etc. Second was a phone interview with a PM person. Here I had a couple questions and brainteasers. After this interview I was rejected.
