Good replies here. I think any 'new' roster you see will look very similar to the old one, that is simply the norm. Some aspects of Qatar are not as bad as people make out...others are worse. But these points are all down to each individual.
Generally the guys who are there any length of time are not able to find a better or similar job in their home country. If you have other options closer to home then I would advise that route. If not, then a job in Qatar pays the bills and keeps you current but is not a long term career airline.
There are some really decent guys there and some real
....much more so than your 'normal' airline. But then the whole setup is a whole set of extremes.
Think carefully and choose wisely.
It was the right choice for me, but then I didn't have to stay there long!
Good luck.
