Hey palm, I do not know your situation and therfore I cannot comment. It has to be your decision. I know many people who do take the offer and many who do not take the offer. Either way you will not be in the minority group.
If I knew then what I know now I would have never left my job. Emirates has a great
PR department in every way, and just as you came down here and showed them your best side so did Emirates. I have never heard of any recruitment process telling you the truth about what you are about to get. Everyone shows you the best side of the job, and forgets to tell you about the other side that always exists.
Think before you you come though, as pilots here on pprune are not just a small group of upset pilots while the rest are a happy bunch.
Having said that I do not want you to think that everyone goes about miserable and upset, rather most of us are looking to jump ship... at some point
