Three referees
Why three? I dont know, but then why not.
My Airline shut down recently and quite a few of the lads applied to EK amongst others, normally what I've seen is that if you pass the interview and they want you they then call your referees. Basically you are in unless your referee gives you a bad reference, so pick your referee carefully. Recently I interviewed with another carrier in the region and one of the applicants told me that he had passed the Emirates interview last year, he had asked his boss to be one of his references, the boss agreed, when EK called him he gave the lad a Bad refernce so he was not selected. So be careful who you pick.
