We are hiring and the hiring process can be found somewhere around here.
B777 is the only fleet currently taking on DEC. On all other fleets DEC hiring has been stopped due to too many captains plus a lot of FOs ready to be upgraded internally.
We need more FOs to be joining urgently and we have seen the numbers of newly hired FOs rising dramatically over the last months!
All comments regarding medical are correct. You better take out some personal cover as well in case you have a family to take care of. Whatever QR offers you is not enough!
