Think long and hard before committing to this place.
By all means come and do the interview, but don't be blinded by the slick 'roadshow' you will receive. If you have friends, or friends of friends, here that you can discuss the place with - then do so.
I came here thinking it was the right thing to do and I have never regretted a career move as much, but, as has been said, uprooting yourself from Dubai/Emirates is not straightforward.
It will cost you a lot of money to come out here and get set up, as an FO you WILL struggle financially(forget saving - your biggest worry will be not digging into your savings every month) and if you then decide to leave it will cost you again.
