QR is a huge multinational, presently world's no1 airlines. Lots of vacancies are coming out due to new international airport and its fast growth. They get thousand & thousands of CV's and it takes time, all you need is to have patience. I am working with QR since last ten years, and when I applied even after interviews, the process took around 6months. Its a positive answer your cv is under preview, there are lots & lots of procedures involved, like verification of your certificates, past jobs & so many, and at the same time other cv's also to be considered & followed up with. This was in short. so I hope you must have understand, have patience & good luck
