Hi all thanks all of you for your comments. It's really interesting. The company is Qatar Airways actually... So I suppose it's pretty much like a government organization.
Currently I am jobless, but I have other interviews and probably soon, I hope, some other offers, which will maybe help me in the negotiation. But I don't know if they are open to negotiate freely in Qatar Airways... I know that in private company everything it's a common attitude to negotiate, but maybe not at QR.
I know that I can't get a total package of 70000QAR, but I am guessing to propose that counter offer, what do you think?

Base salary 20000 QAR
Housing 12000 QAR
Tranporation 4000QAR
Utilities 300QAR
So total package of 36 000QAR... Is it fare enough, good, or too high requirements?
