I'm in the 'flabbergasted' club also fella. I remember being asked numerous questions, at P2 and during OASC, wrt my desired future employment.
I can only assume that you are looking for a personal edge to what you already know. During your training on 55 Sqn, you'll be sent on a couple of station visits before you are streamed - it's a bit like Bullseye, you know, look at what you could have won. These will provide opportunity to get a brief feel for the different branches.
Might be worth doing some homework in the meantime though. Best of luck.
