Ask them for a copy of your contract before you get on the plane out here. If you come out here without insisting on a contract you simply won't get one after you've arrived over here.

Double check the small print about benefits such as medical cover and school fees. If you're out here for a couple of years or more your child will need to go to school and school fees are expensive here by all accounts.

Ignore all the people who tell you to just go for it without a second thought. They just hear rumours about high salaries but they don't work there and don't have a clue about the reality of working really long hours without lunch breaks, the unsocial shift patterns, delays in paying overtime, nightmare bureaucracy meaning that you often have to go into work on your days off to sort out admin problems.

The working terms and conditions are such that while the pay might seem good (but even that's eroded with the exchange rate fluctuations as the riyal is pegged to the dollar so converting back into pounds sterling, over the course of a year it can mean a difference in a hundreds, even a couple of thousand pounds, plus inflation in Doha is at least 13% as much as 17%) it's not necessarily worth the grief.

Do a Google search check out articles in the Guardian, the Times, and if you or anyone you know has back copies of Private Eye about problems with working conditions there's stuff in there too. Things were getting worse and worse and worse for a long time, then there was a change in management. Things haven't got worse, but things haven't really had time to get any better yet either. Hopefully, with the regime change things will get better, but make an informed decision, know what you're getting yourself into before you sign on the dotted line.
