Why don't you write why YOU want to be a pilot, rather than assume that others must have a better reason, which is more acceptable to QF, than yours?
...well Capt Claret, it's a pretty well accepted fact that QF are in the cloning business, and there are most definitely prescribed answers to such questions.
Sad but true. There's a game to be played, and ya gotta play it.
Don't rely on PPrune to give the answers, either. Anonymous strangers are never a good source of information. Just ask around as much as you can (preferably get to know some QF pilots), and get their guidance on the application/interview process.
