I myself am about to apply, recently I've brought friend for an interview, but we are really afraid by a very high living costs in Qatar. Yes the payment seems to be good enough, but I heard you'll have to pay 1/3 of it for accomodation, car rental, electrisity etc. If it's so, it doesn't seems to be worthwhile. And i've heard also there isn't compassional leave! Hard to beleave!
