> I interview programmers and I've encountered this a few times, and yet, I still don't do code tests. I talk to the candidate and you can easily ask the right questions to tell who can code and who can't.

How do you know? Is this repeatable -- e.g. can you write down the questions and the criteria such that someone who is not you can follow them and come to the conclusions you would?

Do you ask all candidates the same questions, or do you go with your gut and hope there's no systemic bias?
