Well, generally, yes you can. But you will have to find a job BEFORE you come to Qatar.
Once you have a job, your company will provide a work permit and then the Residence permit.
The conditions of your job obviously depend on the employer. Some provide housing, medicare, yearly flight home etc.
But,IMHO it is the wrong approach to come here looking for a job...find one on line before you get here .

Are you looking for a job in real estate? I don't think it is a good idea to leave your company in Turkey if it goes well to come to Qatar.
