Argpilot,
Read Ace The Pilot Technical interview and you should be fine with the test.
The CP recruitment is South African (last time I checked it was part of Africa not Europe) and has a background as an instructor. He gave me my sim eval and was straight forward and honest.
As for FAA v. JAA you'll get a sample of JAA in the HPL course. You can decide for yourself which format contains the most "rubbish".
Good Luck!
