Hate to burst your bubble wwIIace but I have not been to EK and have no great desire to. I have attended and passed this type of interview process in the past and it has it's place if you want cadets but there are better ways of screening qualified pilots if you know what you are doing!
Trouble is HR types create little empires for themselves and often know little about aviation or pilots. However, I agree if you want the job then you will of course jump through the hoops, I guess I and others just don't want the job! Good luck to those who do.
