Nope - I've read before that to move teams at Google, all you need do is say so, and you can move to whichever other project you want to - no questions asked. Not sure how any of the less interesting projects get done, but that's just what I've heard.

this is not true. if a team is "hiring" you can transfer in, but the popular ones are full up, and getting in is very competitive. plus many teams are only in a particular office and if are not willing to move to it, then you are out of luck.

that said, transfers are supported by management and there's a nice internal web app for browsing which teams have reqs and for requesting a transfer.
