I think that depends on the person doing the interview. Like if I were interviewing someone, and discussing salary was part of my role, and they named an expectation 2x what we were planning to pay, I'd ask them why.

Perhaps that's the norm where they come from? Maybe they heard Google paid that much? Maybe they were just throwing out a high number to anchor high?

It's funny to imagine the interview game being like the dating game teenagers talk about, where one wrong move, facial expression, or word uttered can wreck everything.
