To be able to be allowed to do a course for an airline such as Qatar, it needs to be recognized, vetted, and approved by the national aviation authority, and normally middle eastern nations just "copy n paste" from JAA in the old days and EASA currently. Let's just say it was never done.
And I can tell you one thing about STAA, they like to make sure they get the customers paid up and ready before they even prepare the product. E.g. Some private candidates went through the whole course saying they'll be inducted by Tiger at the end, and at the end, they said no such thing. And a whole bunch of private guys jumped ship because they were being pushed aside for the MPL programs, CSA, and other guys, last I know, those guys were averaging a few hrs in 3-4 mths.
