5 How do I prepare?

You're already ahead of the game by just asking that question. As a professional interviewer I can tell you it is so rare to find a prepared interviewee - mainly we talk to rabbits in the headlights. Here's just one of many things you can do to prepare. Ask yourself 'What's the question I would most not want to answer?' Don't go in on a wing and a prayer in the hope that they won't ask that question! Work on that answer! That's a real confidence arrow you need in your quiver.
