QR indeed does do fast track for qualified candidates. I had 1400 wide body PIC and about 10K total time, but not the 2000 wide body PIC required for DEC on the B777, so I was hired as FO on the B777 in 2012. Not much later than two years after final line check I was offered command, which was slightly more than 3 years from DOH to LST very recently for command on the B777. And I did not pester them, they came to me. Three years went by fast, and if you show up for work on time here and don't bother anyone, the paycheck is good and it is on time, and the people are good to work with. I've worked for worse outfits I can tell you.
