Before you consider what you need to be asking, I think you need to know what it is that you will be spending:

If you are a family and looking for a 3 bedroom place ( apt or villa) then you need to know that you'll be spending at least QR 10,000 to 16,000 per month!

House rent here is a night mare!

Consider paying a monthly installment for a car at around QR 2000 / month

Are you medically covered?
Does your company offer school allowance? (this is very important)

And in a recent study done by Gulf times, it stated that a family of four ( parents and 2 kids) required a salary of QR 29,000!

So my friend do some hard bargaining!
