Well, it is not "The Apprentice" so they are not looking for buffoons and/or those who are just plain annoying. Initially they want answers to questions, sample images and a video to see how well people shape up on camera. Most will fall by the wayside at that stage, especially the video I suspect. Looking good on camera is not that easy and is a comparatively rare skill, which is why TV presenters and actors get paid so much. After that, I would expect interviews and test screenings to establish the final contenders. They are going to want people who look good and are interesting, as well as being competent photographers. If you have access to Sky TV, you can look at the first two series to see the type of people they select. Even the trailers will give an indication.
If you still think that you have got what it takes, go for it. If nothing else, selecting images, answering profile questions and creating a two minute video will get you thinking about yourself and your photography. Win or lose, you will gain from the experience.
