Skysoarer,
I am also having problems getting hold of information about BE. Their website gives a reasonable amount of info and I have got hold of thier timetable (just a hard copy of what is on the website). As far as the interview goes I am as uncertain as you as what to expect, please let me know if you have any more information. I noticed on your original thread that you have Stage 3 on the 10th of December, I've got mine on the 11th, I presume this means they are running two days.
All the best.
