I don't know what questions they ask these days but I do know that when I did testing around twenty years ago it was very difficult and I couldn't get through the psychometric evaluation either. I missed out twice and replied again nevertheless. The third time I applied I was already working in the Territory flying light aircraft and they sent me tickets to fly from Victoria River Downs (Miles away from anywhere) via the mail plane then Airnorth to Darwin and then via Ansett down to Adelaide because the Darwin testing office was closed. They included accommodation and seemed very keen to have me reapply. I cannot begin to imagine how much that cost them.
I still don't really understand why they elected to do that but it's certainly evidence that they like persistence.
My then boss didn't allow me to take leave and I don't think I would have cut it anyway but I persevered with flying and never looked back.
