I advise you to go direct to their office in Al Saad for QP Co., Ask for the HR which is at the 4th flr i think. Ask for aa application form and fill it up. If you think you are very much qualified in a certain position,(in their site there are available post they are looking for hiring)You must name the positon you are applying directly. Submitt your CV along with the application form. Take the no. of the reception of the HR OFFICE, CALL AFTER 10 DAYS IF they did not call you in a week. Call again every after few days and try to go there personnally to verify. I once seen the inside office of the HR head and there are plenty of application papers in his desk and i think he just look for it for those applicant who are verifying their applications. Goodluck!

Tip: Simplify your CV, but direct what position you are applying for. If Have morethan 5years experience in the Gas and Oil you have a chance i bet..Goodluck
