Hi Waricks,
Im jst about to begin my course on the 14th, and it took about a week/2weeks for virgin to offer me an interview date. Its all done on across the net now, although i have heard some ppl have had telephone interviews aswell?
Basic stuff really, group discussion and tasks are first, then a 2 to 1 interview covering your history, what you have been doing etc, and what you can bring to the job
Hope this helps and good luck
