This forum is not really helping if there are questions, that a thing any PPRUNE long term user knows. I got to know some very nice chaps but only via PM. As well for EK. But do not expect anyone will post anything helpful here in one of this useless threads.
If you do NOT get any useful hints via PM try to invest a few bucks in "latestpilotjobs.com". They have a collection of interview questions, as well some kind of training for their "skill" test. I invested for a 3 months membership(never went to the EK eventually as there are better jobs in Europe, at least you are at home which is Gold for me) and found the training actually pretty good.
Some people that actually went to that EK interview told me that the preparation was quiet helpful.
Will consider EK(or China, let's see which one comes up with the best term till then) as a "pre retirement" job for my last few years in aviation(if the money is right and the kids are out of the house), not before.
Terms just went south (
) down there, so need to rush to return to the ME
