I've found that people who are open usually think of the interview as a way to learn new things and to determine whether it's a good fit. They will ask questions and seem to enjoy gathering knowledge.

Rationality is more of a value than a litmus test. Those who value rationality will understand systems thinking and will tend not to focus highly on authority (either being authoritative or deferring to someone else's authority).

thanks sounds like you've done your share of interviewing. It would be great to hear more about your experience if you ever want to write a more lengthy blog post on this subject. I still find it very hard to predict who will make for a great employee.. provided they do ok on technical side it's still more of an intuition thing rather than process.

I should do that sometime. For some reason I'm much more inspired to write my ideas in a forum like HN than I am in a blog post or writeup.
