Google Project Manager interview questions

About 2 months long. Phone screen, with recruiter, 45 minute interview with PM, and the 5 virtual interviews. I was rejected by the Hiring Committee , ultimately. Recruiter did not give any feedback (no scores or hint of anything). It is a long, time consuming process. I did a lot of prep and even took a few days off work to prepare. I don't regret it because it prepared me well for subsequent interviews. The process was pretty smooth - though almost a month passed between my virtual "on site" interviews and rejection. The interviewers, for the most part, were very friendly and the questions fair. I thought the interviews went very well except for one. For that one, the interviewer was on a treadmill and her head was bouncing up and down, which I found distracting. I also had trouble understanding her. Debated asking her to stop exercising but in the moment, could not.
