Google Project Manager interview questions

Had one call with a recruiter and then a phone screen with a product manager. The phone screen included one problem which I had do analyze holistically - strategic, business, functional, technical, execution, marketing. The problem was related to an enterprise collaboration solution. Following that I was invited to an onsite interview. Most interviews went pretty well, covering mostly functional design issues, sizing and one deep technical interview with an engineer. No questions about my experience or past work - only skill questions (e.g. estimate how many photos are stored in picasaweb, design an ideal alarm clock, describe the most innovating product you've heard about lately, etc). Didn't get an offer although some interviewers were added during the day. Maybe next time.

The overall interview process started off well. Expectations were set about a phone interview followed by a day of in-person interviews. However, once the process began, it became clear that they have trouble following their own process. Ultimately, it took 2 months to get to the offer and by that time I find another job. The people are smart and seem fun to work with, but if they can't get their hiring process right, there are going to be more challenges in the day-to-day.
