flyaway79,
Congrats on getting invited to the VRD, it really is a fun day, if not a bit nervy. I was SO scared, I was more scared about all the people that would be there. But Virgin do it really really well. You quickly start to feel comfortable, and start to talk to people, and even meet new friends.
My tip is to SMILE, be approachable, talk to people, candidates, and the Virgin staff, they are there to meet you. Im kinda shy, but after 15mins at the VRD I was fine. The hardest part is when you first walk in for the day. Another tip arrive a little early, that way you can start to introduce to other people as they start coming in.
Remember to be yourself and be honest. The virgin staff are trained to see through a fake person. They want to see who your really are!
So, in closing, SMILE, be approachable, be yourself, and have a good time.
Good luck!
