In reply to Catriona:
The "can you communicate complex ideas clearly" issue should be covered by your lecture.
I would carefully prepare answers to the following questions (amongst others):
- How would you go about designing a module in [your subject area]? You'll want to show that you can think through broad issues to do with what to cover, and how this is best delivered.
- ...and how would this be best assessed? Looking for issues to do with fairness and validity, but also that the nature of the assessment will motivate students to engage effective and comprehensive learning.
- Why teaching, and why this department? (Looking for plausible, positive reasons)
I would also make certain, before the interview, that there is no expectation that your role will involve research, or consultancy, or anything other than teaching. I would be suprised if this is the case. Unless they give you a definite no, then you should also prepare answers to questions about possible research activity (or other non-teaching projects) including of course, ideas for sources of funding. These should be concrete, well researched and realistic.
In my experience of these things (social sciences, with research focus) you can pretty much rehearse everything that you are likely to get asked or, put another way, if you rehearse good stuff then you will almost definitely get a chance to say it in the interview. So the key (I think) is lots of preparation, combined with passion, enthusiasm, and coherence in the interview.
