Good luck lads.
I interviewed in Jan 08. Great experience put in the work and you will enjoy it. 50/50 personel/tech. Know why you want the job away from the big shiny Jet. Know the pro's and con's of living in HK and why you don't want to stay in Aus. Be careful what you bring up they will probe, make sure you can back everything up. Most important i think, BE YOURSELF.
Tech, A few Q's straight from HTBJ. If you have done any research or have any friends with previous interview questions you will have seen most of the Q's asked. Aerodynamics is a given swept wings etc. A lot of the tech was scenario type questions more of a conversation mainly based around your current type. Know everything about the aircraft you are flying. What are you going to think about if .... happens? etc. They seem to be more interested in how you think not what your answer is, of course you want to be in the right ball park. Don't be afraid to smile and have a laugh if you can personality is important.
The interviewers were very pleasant and make you feel comfortable. Just don't get to comfortable stay focused don't let your guard down.
Again good luck
