JP,
Please be aware that this is not a conventional country and freedom here is restricted by the system:
- You are not allowed to work for another company, only for the one that sponsors you. For you to be able to work for another company, you will have to leave Qatar and reapply 2 years after you left;
- You are not allowed to exit the country without an exit permit authorized by your employer;

There are other issues that you'll feel restricted, but then again, if you come, you will have plenty of time to face them yourself.
