Great posts there, 515!
The biggest problem: a lot of guys joining believe the lies they are told at the interview and join without a waterproof backup plan (or spend their money to settle in Doha and can't really afford to leave this place for a while)!
When joining Qatar Airways, always make sure you have a waterproof backup plan! ALWAYS!
I was fortunate enough to have one, took the risk of joining (despite the information I had found on pprune -- of which 90% turned out to be true!), liked it until the company refused to give me what was legally my right (won't go into detail, but getting a lawyer in Doha against the national airline is not quite as easy as it seems), and eventually went back to my old job!
So, join this wonderfully ambitious airline of happy people giving jobs to everybody so generously (just quoting Mr. N/A...), but make for god's sake and your family's sake sure you have a WATERPROOF BACKUP PLAN...
and enough savings to afford another move (backwards)!
