I guess the questions were more weird than anything... I remember when i went for Qantas 4 years ago we had to answer about 500 questions... it was like answering the same question but asked a different way... I am much happier answering 30 questions instead.
I have been to two Virgin recruitment days. One with V australia a few years ago (got the job but turned it down for Etihad... what a mistake!!) and one with DJ in 2010. They all seem to run the same...
1. Introduction
2. Company Profiile
3. Group Activity
4. One on one interview
They are forever watching you. Some say they there might be a "candidate" in the group with you who is actually an assessor... so just make sure you are not too "relaxed"... Just be yourself but professional. If you can tell you're not youself, they can too. And just get involved in discussion as you would normally.
Good Luck!!!!
PS: if things have changed since... be sure to let us all know...
