Google Project Manager interview questions

Interview process was fairly insulting for a high level position. The process seemed geared to evaluating recent college graduates, not anyone with real world experience. Focused on evaluating hypothetical situations and thought problems instead of the tons of real experience I had. The people who do the interviewing are not those in the same group you would work with (I was told this was a Google policy), so no chance to evaluate personality fit with future coworkers.

I received an email scheduling a phone call interview. On the phone the interviewer asked very generic and easy questions about Google (what is Google's primary source of revenue?) and soon it was over. I thought it was just a screening interview and I checked that I had nailed all the answers. I got an email later ending the process. I'm still confused about the experience as it lost mine and their time.
