I worked over there a long time ago. There was general agreement among expatriates that working in Hell was a better deal. The Saudis do not honor their contracts, and will even try to get you to sign another contract after arrival. This will not work in your favor. The hard core religious groups control all aspects of life and they do not like western expats. I strongly advise you to talk to someone working there now prior to jumping on a plane. Saudi is one miserable place to be.... Due diligence in researching what the conditions are will pay off. The money over there is not so good anymore either.
I have been back for visits (Based out of Dubai..) in the last couple years and while it has lightened up, it still is the antechamber of hell...
Fair Warning!
