Another item from a Google HR guy, passed on secondhand:
All the time, when someone comes in from India to apply, the scene goes like this. She says, "I want to earn 20% more than this." I say, "Wow, girl, go take that 20%."
They do the eye thing, thinking quickly — it's like watching a tennis match — and they say, "Well, my first priority is Google." No 20%.
