As mentioned SIM ride has been a 300, learn the power/attitude/speed data they send you and it's much easier. Not sure about the interview but general IFR and brush up on your current types. Basing: expect Toowoomba or Brisbane. Not much happening in Cairns at the moment.
The lack of responses on Pprune probably says more about how much rubbish has been posted on previous Skytrans threads. Overall for flight crew it's a pretty good company to work for.
