I interviewed for a position last year where the company had a very successful product and was growing, but still small. They wanted to restructure everything (the way they code, teams, management style) to be more like Google.

I made it to the last interview stage, which would have been a 4 hour remote white-boarding session, where they would give me something to code and a team of developers would watch me. I turned it turned it down and found a much better position the next day.

The first stage of the interview was light technical and almost all a psychological test to see if I would be a good 'culture' fit.

The interviewer was a first-time 20-something manager that wanted to make a name for himself and had read a few silicon valley books about technical interviews. He actually told me this.

Most companies aren't Google and shouldn't be emulating much of anything there.
