Google Product Manager interview questions

The interview process was pretty straight forward. I got an email via LinkedIn from Google recruiter asking if I was open for a role as a PM, I was not (I was already working for an Internet giant like Google), but since it was Google I wanted to give it shot and said yes. After couple of email exchanges, I decided to talk to the recruiter, she called me and explained every single process/step that happens in the recruitment/interview process (which I liked the most), she also sent me a follow up email with a lot of reading recommendation/material so that I can prep myself for the Interview, which was amazing. Since I was in a remote location, my interview was over the phone. After the overall process, I felt like I wasted my time and reason for that is, the recruiter mentioned that I didn't do bad, I was better than many others they interviewed before, but the person who took the Interview felt like I was not opening up on my ideas and holding my thoughts back which obviously anyone would do, but the only reason I hated the entire process was that just coz "one" person had this opinion they decided not to offer a role, ideally at least 3 people should interview to understand if a candidate is suitable or not, but here one person’s decision was enough for them to make a quick decision, sad policy, sad thinking.

It was mostly straight forward. Entire process took around a week. Lots of pre-vetting prior to the actual interview. Since it is contracting position, just one in person interview with the hiring manager.
