Depending on how relaxed and approachable you are, these disarming questions might come early on or at the end. Typically, they'll follow this up with getting-to-know-you chit-chat. It's important that you keep your comments consistent with the questions you answer throughout the interview. For example, you might have said earlier that you have open availability. Once you lower your guard, you reveal you have a band and perform nightly and they should come and see you play sometime. While you were trying to make a friend, you just contradicted your declaration of having open availability. Be friendly, make friends, but keep your eyes on the road at all times.
