Hello there,
I did my interview process in January 2013 and had the good news in February. But we were told that we are now in some holding pool as their needs was less than expected. (Maybe the fact that the fleet expansion was also on hold...).
Anyway, the process was really relaxed and the people in the recruitment department are very friendly and helpful. They really put you at ease from the beginning.
PM me with your e-mail address as I did a PDF of 7 pages who explains the process from A to Z. But I didn't specifically explain the exact examples we had during the interview as it will not help you at all. So you don't go there with specific examples in your mind. You have to be open to everything.
Personally, the first part is the part i don't like. You have to "sell" yourself in a certain way. And the part I loved was the sim ride. There is no bull****, no fake, and I think as an assessor you see DIRECTLY what kind of guy you have next to you.
