Be very careful as things are EXPENSIVE in Qatar at the moment. Rent is though the roof (so to speak), public transportation is very spotty, Resident Permit process is a royal pain in the, little things like phones and Internet connections are time consuming process, driving is a life risking adventure everytime, other than that, Qatar is a great place to live.

Make sure that you get things worked out before taking the job as it is a challenge to find "good" housing at a fair price. Anything you would want to live in, is going to be QR 6,000 per month and up. Parts of town will take you an hour to get around or through, traffic is bad and getting worst.
