I would probably forget any possibility of an FO 330 job (or any mainline FO job for that matter) - cargo 747 FO jobs only for now. Mainline Captains are all they want - and other than some transition guys from the 744 mainline and a few Silk Captains, there haven't been any new DEC 777 Captains in over 2 yrs.
To all of the prospective pilots out there - SIA mainline is a very good job - BUT if that bonus goes away or significantly reduces, Singapore will be basically unaffordable with a family. Nice lifestyle now, but slowly (and surley) changing unfortunately.
