As Bubba said HTBJ is a good source of info as alot of the questions will come from there. You will also do a written tech quiz with about 30 questions, not too hard but I think the Capt XYZ has a sample of them. I got nailed on questions about HK and about family, personal issues and all that. The technical was very heavy on aerodynamics, What type of aircraft the model in front of me was, lots of q's about Cx, number of aircraft/history. If you don't know the answer just say so.
If your in sydney I recommend an interview coach. It helped me out and opened my eyes to alot of things I had never thought about.. And I got the job.
PM me if you want contact details. Good luck
