Does anyone think QF are so capricious as to arbitrarily cull someone who has 'excelled in every component'? Or is it more likely that said candidate didn't excel in every component despite what they may have thought? A helmet fire on the assessment day or in the sim? An issue on the psychometric confirmed during the follow up psych? Maybe presuming that the process was a box ticking exercise?
I don't blame those who didn't make it through seeking other avenues and opportunities. Good luck to them. I hope they succeed and that the QF experience helps them to get through the next application process. For whatever reason, on the day they weren't competitive in the QF process.
