Hi The Answer,
Well done for making it through the day. I guess it was such a big event as it wasn't held in Luton...
Anyway, you made it through which is the main thing :-)
A bit annoying though that you will have to travel to Luton for your interview...
If you haven't had your call after a week or two I would call them myself if I were you. Just to remind them of yourself ;-)
And you are right, the staff is usually pretty good, friendly and helpful.
Hope your personal problem has been sorted. Good luck for the interview :-)
