Aussie029,
Just the standard interview stuff mate. Learn as much as you can about the aircraft, where they fly, what the company has been up too(all available on the website).
Also revise your IFR theory, supersonic aerodynamics, meteorology, IAP procedures etc.
Then to top it off, sit down and think about some questions they may ask you in the personel interview, if you have trouble, just do a search on the net for interview questions. Also think about what you could ask them.
