Valkyr,
I did the apptitude test and all can say is it was enlightening. Just hope for a great or a terrible score, them's the only things that make the go/no-go decision easy.
The de-brief was 1st class and just what I needed at that early point. My momentory mentor was an a current corporate Jet captain. We didn't just talk about the test (hardly at all actually), but more about the industry, the way forward, what to concentrate on, what they look for, etc, etc.
Go for it!
HWD.
