Of all the interviews I've been to, I felt the most uncomfortable at Google. I was surprised how obvious it was that many Googlers are stuck-up, full of themselves, not just the aforementioned person.
Just because, they are Googlers.
Disclaimer: I'm not generalizing, and do have friends working for Google. Also this wasn't in the US.

Even the almighty Google has people who don't know what they're talking about. Unless they're all like that, I'd write it off as a fluke. It's an embarrassing fluke for the interviewer--this is their problem, they should know it forwards and backwards and all the common solutions. If you get a lot of interviewers like that, then you should run.
