Cloud Nine... congratulations!!!!
I am sooo happy for you,
Look at your persistance... dedication. See how things turn out when you give it your heart and soul. I'll be praying for you on the 30th. The only advise i could give you would be, "Be Yourself"
I am not sure whether that will help you with Virgin Blue, as they conduct interviews differently. But i have been very successfulin the past and present with interviews, by being myself, and prepared.
Anyway... god bless!!! and i hope your successful, because its people like youself, with all your dedication and passion that makes the airline industry, the best career to have in the world!!
