Are you qualified?
Nationality?
There may not be any vacancies for the job you want or far more qualified people getting interviews first.
Qatarization issues in your chosen field?
People are always leaving QP, maybe you're not what they are looking for.

You need to supply more information before anyone can help.

Peace
