I was directly interviewed by several top executives, so this isn't very relevant to most interviewers. If you are, they'll sometimes spring it on you. In my case, I got a 15-minute heads-up.
One of the founders asked me a question that I thought was a terrible interview question, and I refused to give an answer. He was asking me to estimate some technical quantity of their datacenters, and I insisted that I would not guesstimate it, but I described how I would measure it and where I would expect the weaknesses in the design to be.
One executive asked me why I was using the iPhone and not the Android. I said the Android still sucked (this was years ago).
They still hired me, which I took as a very positive thing. This is not a culture that has a problem with being challenged. It's an innovative, creative environment that welcomes a debate.
A logic problem, IQ-like
