I have to say I've found it to be as spamcandriver says. There are days when what LukeST said applies too although the remarks about the training are well wide of the mark in my experience (that may be partly down to different fleets)
This is a place I'd never have contemplated coming to myself but needs must and it was the best offer at the time and still remains so. The other 2 airlines I had interviews at have both since gone out of business.
As to whether to choose this over ryanair for a cadet/SO programme - that's a balance. I accept that the picture of how you're treated in ryanair probably doesn't entirely match reality but I suspect that you'll be better treated in Qatar Airways by a long way.
