I went out there as Planning Manager designate at the end of '98, destined to replace the guy who was leaving within a couple of months. I left before he did,as did 7 engineers. (pay and contract my main reasons)
In all fairness, the Eng Manager, Tom Botha is a very good guy and is trying hard to turn things around. Problem is they do have political problems with HR and the real world and I can not see them paying so well for lic engineers. I know Tom managed to get a few SA guys to come in, but I am not sure if they are still there.
Best bet, apply and get a trip out there for an interview to see for yourself. Bear in mind Qatar is small, flat, desert. Beer no problem, (women ,if your single..more of a problem) Social life around sports and home entertainment. You need to get an exit visa everytime you want to leave..so quick weekends away in DXB are not that simple.
Good luck -
