Following on from the previous thread, I know it can be frustrating to wait for an answer guys, but three weeks isn't too long to wait. This isn't exclusive to MAM/Qantas; unfortunately it is the nature of the industry, and it is not at all uncommon to be waiting months for an answer. I was lucky in that my process was relatively quick - I got my yes call within a month of my interview, but it was still a good five months between applying, getting an interview, getting the job then commencing and completing GS. Be patient and remember that no news is good news. Good luck.
