MNG, I am not surprised that you haven't been selected for the CX cadet course. Personally, if I were rating you, I would say
ENTHUSIASM = 3
GREED = 9
What you need to get in is
ENTHUSIASM = 9+
GREED = Money? I get PAID to do this?
Consider that CX are willing to poney up over HK$1,000,000 for ADL, have you barely productive for over 3 years as a very green S/O while paying you HK$25K a month ++, (that's another HK$1,000,000) and then put you into the right seat of at least an A330, the LAST thing you (as a cadet wannabe) should be asking is "Btw, anyone got actual salary figures or knows where I could find some for myself".
Get real. Either come back with an ATPL and 2500 hours or shut up and take it with a smile on your face. CX owes you NOTHING.
