For each behavioral question that you are asked, I would follow it by asking the interviewer a comparable behavioral question. This is only fair. Insist that all interviews are supposed to be a two-way street. It's okay if it puts them on the edge because that's what they're doing to you. If they want to how you behave, you should also want to know how they behave. Also, this should use up about 50% of the interview time, saving you from half of their questions.
Just flip each question and ask them something along the same lines. For example, if they ask you about a time when you disagreed with your supervisor, ask them about a time when their subordinates disagreed with them. If they ask about a conflict with a coworker, ask back the exact same question. If it's about your biggest failure, ask about their biggest failure and how it impacted the team working under them. If they refuse to answer or say that they don't have any lessons to share, then you know they're psychos.
