I found the "would you take a 10% paycut" matched my experience precisely. Back when I worked at Microsoft on developer tools, I would sometimes get contacted by people who were in the finance industry with salaries 2-4x what we could offer, and often transitioning from some nice CTO/Chief Head Architect title to Software Design Engineer.

But, universally, they were _excited_ for the opportunity to work on real compilers, tools, etc. and especially to be surrounded by people they could learn from. I'm would expect the lurking Google hiring managers have experienced the same thing.
