After several years of various flavors of behavioral-style questions, I ran into a situation that I didn't expect:
The candidate recognized the behavioral pattern, and then declined to actually give specific scenarios out of the past and explicitly said that the answers would stay at a generic level.
I went along with it just to kind of see how it would go, and the individual is highly analytical from what I can tell with a highly technical background. For me, the explicit rejection is a big red flag. I've had people take time to think of something, which is fine. I've had things that fell apart when i probed for depth, also to be expected. But I have never had someone recognize the style of questions and reject it flatly. I don't want to be too biased in my assessment, hence I am seeing if anyone else has run into this before (I am sure it's happened to someone else),
