Google Project Manager interview questions

After a 30 minute phone screen I was asked to do an interview. Despite interviewing for a job in Canada the interview was done in Mountain View. I had 5 interviews. The first 3 with other PM's, then one with a Dev, and one with a PM manager. Most questions were product related (Lets design an X, who would you improve product Y).There were a few questions designed to measure mental horsepower (Estimation, Puzzles). The key with the interview is that you have to get a few people to really strongly support your candidacy. If everyone thinks you would be a fine hire but none of them would fight for you ,you wont get it. So do what you can to make a strong impression. If you didn't do well you will get a quick no. Otherwise you will go to a hiring committee which can take up to two weeks. If they say yes, you probably have the job, but they have an additional 2 weeks of referencing checking and executive review before you'll get an offer.

it is a 3 stage process. recruiter, 1:1 interview for 60 minutes then 3-5 interviews onsite. The whole process is very secretive is was impossible to find out if there was a position near me and basic info on what projects they had at the closest office. I made it through all 3 stages and feel like I did very well and expected an offer.
