Commuting pilot,
At this time I understand that A320 DEC are not really needed by Qatar because of the huge number of DEC that is already on the holding pool. That might be the reason of such a delay in calling you. On the other hand you can never know how and when Qatar is calling you for the interview because they really do not care about you as a single, they manage big numbers.
My best advice is to wait, sooner or later they will call you.
It is still Ramadan there so things are even going slower than usual, usually after a couple of months you get the PSA to do (don't know if that changed). With the Ramadan on the middle it might take a month longer.
Selfmade92,
I do not know anyone, but since there are no unions in Qatar and the airline is managed like a family business I wouldn't be surprised at all. (Maybe because the whole Qatar is OWNED by a family)
And actually I don't care.
Why do you ask?
