For those joining maybe worth to read the latest incident in Australia and especially the comments in the Av herald. If you join Qatar, fatigue will ruin you, if you have an incident/accident you just added a serious incident to your license and the company will fire you, they will never ever side with you. Best luck finding a new job with an accident /incident on your license ! Multiple crews have gotten heart attacks etc in the last months litteraly dropping in the crewroom after spending 180+ hours in the plane.
Those who join from another airline litteraly have to be out of their mind. Be careful giving up your job since at anytime the company can change their mind due to operational requirements your joining offer is not valid anymore!
If you are without a job don't bring your family you won't see them anyway and get a good plan for your divorce later down the road.
As a good news the company guarantees from January, 4 consecutive days off per month on the condition you will not call fatigue ever or that option will be removed for you!
Best of luck...
