I recently joined Google and it definitely didn't work that way. You aren't usually interviewing for a specific team, like with smaller companies. But once you get past the interview your recruiter works with you to find teams that you will be interested in. In my case I talked to 3 hiring managers that were all working on the exact type of project I expressed interest in. I've seen it work this way a bunch of times when hiring for my team since joining.
I'm sure it doesn't always work this way but from what I've seen it's certainly the intention.
