I passed the interview (for the second time) last year and eventually turned Google down in no uncertain terms. But the last thing I was told is that the offer is good for a year — presumably not for the team I was looking at (I was being hired to a specific team which was a bit strange, perhaps?), but to go in the team match system. Of course I'm sure it's no longer good with the hiring freeze, but the point is that Google is so heavy on the "no role needed" train that even when you're recruited for a role, you're apparently still able to turn it down and still join Google later on a whim.
