These are the questions I might ask during an interview, depending on the information I already have, the company, and everything else. I won't ask every single question, and neither should you. Life is too short.
This was, at the beginning, an aside to this article, on my blog. It grew as the time went by.
Some questions don't necessarily reveal what I want to hear, and it's on purpose. If you want to know my stand on things, you can still read my blog. Most of the time, I focus more on the business / people / culture / processes. To me, it's where things can go eerie quickly.
