Personally, I have always approached interviews as an opportunity to either teach or learn. I pick a subject and drill down until either the interviewee reaches their limit of knowledge, or I do. Why is it like that? How does that work?
Then, we have a discussion. One (or both) of us is learning and we work out the whys and hows together. If I'm the one learning, and I hope that I am, I fact check the discussion after the interview. If not, I get a strong indicator not just for the technical level of the candidate but also how they operate at the edge of their comfort zone. I've found this can be a strong predictor of future growth.
