Wait. You didn't know what position and location you were being interviewed for? That kind of arrogance from a company can only exist if the job seekers are desperate or perceive any job at Google as nirvana.
I think you're misunderstanding how the process works. It's not like they wait until they're ready to hire you and then tell you where you're going to work -- they ask you where you want to work. After I had passed all of the interviews, they gave time to consider the different locations and pick which one I wanted to work at (I could only pick a location that had available positions, of course). After I had accepted the job offer, about a month before I started, they contacted me again with a survey that asked me about my interests and skills, which helped them place me on a team. Since I'm working at a smaller office, there were only two team choices, but the larger offices (ie. Mountain View and Seattle) will give you several choices. On top of that, you're free to change teams after as little as a year. So I would hardly call any of that 'arrogance'.
