What fleet they offer!
Well, the fleet they are offering it's entirely up to their needs. At the moment Boeing experience is a big plus. You have probably heard that during the Dubai Airshow 2005 EK ordered additional 42 B777's to the top of all the others which are still undelivered.
I am at the moment on the B777 transition course, on the short transition course. I have had only Boeing experince and that is pretty obvious that they put me on Boeing. They are not having Airbus courses at the moment as far as I know. I might be wrong? They do have also longer Boeing courses coming up, but you never know what's happening. The situatioin changes daily.
EK is having a huge expansion going on, there is a new destinations coming up and when the B777-300ER's starts to arrive next year there will be many routes covered by Boeing rather than Airbus. I haven't mention anything about the B777-200LR's which are coming up too, then there will be another ball game to play.
About the interview, they are not looking for any specialist, you just have to be your self. They do have a scale where they want you to fit in. Think about all 60-70 nationalities only on the flightdeck! They are keen to see that you can fit your self in multinational enviroment. This doesn't fit to all. Simple.
Good luck.
