I got roped into one of these idiotic interviews at a Very Important Company.

Them: How would you solve (well understood, theoretical and tedious to solve problem). Me: I'd Google it. Them: That's cheating. I want to understand how you think about the problem. Me: We're not in school. You'd be paying me to be efficient and solve problems. Why would I waste time on something I can Google. That's how I think about the problem.

And that was about the end of it.
