I have been in Qatar 3 years. The Salary Range I have noticed, have been offered and have offered (as a manager at a leading bank)is wide.
There is no standard bracket whatsoever. For the same JD (Job Description) and requisites, the salary range is around QAR 12,000. Ie, it could be anything from 10,000- 22,000!!!

For example, a Marketing/Sales executive with aleast 2 years experience in Qatar is offered anything from QAR 2,500(+Incentives) to QAR 10,000 (with incentives). It all depends on the Nationality of applicant,the Company and the 'DEAL' in the Interview!
