A330 has the most interesting destinations as it goes in all directions 7 hours+. One sector and overnight. Lots of time away though.
If you are A320 rated you will probably end up on it here too, but not guaranteed. Supply and demand at the moment will decide where you go.
If you get it and you're current expect a short and intense course. If you're rated but haven't flown it for over 7 years, you will do a full TR, either here in Doha or in Toulouse. Pros and cons, the food in Toulouse vs getting QR SOPs correct from the beginning in Doha.
