Blackprince77,
I had a notch under each of those points you mentioned and a few extras, including a previously unsuccessful attempt at the ADF pilot selection process!
I'm not qualified to judge what it takes to get through that interview, so I'll say this: I think all of the above helped me to some degree (I have no idea how much), but showing determination by coming back after taking the failure as an opportunity to improve myself was the difference I felt. Having said that, I'm post FSP/OSB and just waiting for a call, so I'm not "in" yet.
Best of luck!
