Guys there are sample rosters for all the airplanes, I believe, posted in this thread. You may have to go back quite a few pages to find them.
For what it's worth I interviewed earlier this month. Unless they are using different tests for different groups, the technical exam will consist of 50 questions. If you pass that, proceed to three-on-one panel interview. If you pass the panel, continue to the simulator assessment (mine was A320)
Studying ACE and JAA material is good for the technical, no idea what the passing score is. Panel interview is like described in the gouge, as is the simulator. A good idea is to use flight simulator on your computer, and a joystick if you have one, to learn where to look for information. The Airbus screens have things displayed a bit differently than some other EFIS airplanes.
Haven't heard anything yet. Hope the info helps.
