devil-in-disguise ,
mini cooper has some very valid points. It is very easy to dress up the EK package to sound delicious, but there are some fairly large stones under the skin and although the good bits are appreciated they do come at a greater cost than would at first be appreciated.
Many who say the water is lovely have already got the best out of things here and have little appreciation of the situation you may soon find yourself in. Do attend the interview with your eyes wide open and do ask as many questions about schools accommodation and realistic command prospects.
Be aware that the contract is for the company's benefit and does change at will, rarely to suit you. On the other hand if you have no job you may have no choice. The roads will be a little scary too. The tax-free thing is compensated by the fact that the salary isn't the most generous, but the lack of any pay rise is slightly offset by generally good bonuses and an increment.
Positive bits are accommodation is provided (a bit of a gamble and one you have to stick with), the schooling is OK (if you're lucky enough to get the kids into a suitable one), and you won't get cold. The flying is quite busy but some good routes on some new aircraft. And of course the company provides transport to work; a perk that I do appreciate.
My view is - if you're out of work come, if not don't imagine things are any greener in the desert. Hope this is of some help.
