You have to be part of the elite Air NZ family to get an interview or you will have to do a lot of Voodoo rituals and dance with skull and bones on a full moon night to get an interview....
I know several people who have failed more than ONE flight test more than ONCE and now work for cook/nelson/eagle.
Waren9, when you apply they ask if you've failed any flight tests. It would be in your best interest to tell them the truth as if you don't they will check your logbook at the time of the interview and see you have failed a test and that won't look so flash.
