Many people may want the very opposite experience of that which I tend to admire in an interview. It’s just part of being a good host. A CV in-hand, or a laptop, or an open notebook directly in front of you communicates an interrogatory dynamic. Describe a problem you’re having — at work — and work through some possible solutions, however they wish to (talk, whiteboard, code, operatic verse, whatever). If they’re hired they’ll eventually know the good and the bad anyway.
