i had such an interview a few months ago and will start teaching in October. before i went to the interview i asked some friends what to expect. i was told i might be asked questions like "how would you handle a 'silent class'?" or "how will you include those in discussion who never talk?" or "what would you do about a confrontational argument in class?" or "what would you do if someone starts being offensive?". at the actual interview, however, none of this was asked. rather, they wanted to know about my expertise on the subject. not in an exam way, but rather like "in what contexts (courses, classes, essays, dissertations, current research) did you deal with this and this topic?". and they wanted to know about my previous teaching experience, what it had entailed, which was a bit daft since that was exactly what i had to write about in my application.
