I think Sharp Airlines offered a cadet scheme in the past, they might still do it, one would imagine it would be less competitive vs airlines.
Yep, it's still around. It's a pretty expensive program, but you get a 1-year contract as an FO with them, where you rack up a minimum of 650 hours during your tenure. I believe it's the only cadetship providing employment, aside from Rex. Cobham might; I'm not sure.
Not sure what you mean by good performance within a cadetship.
I guess I'm referring to demonstrating a positive mindset and enthusiasm for learning, coupled with a mature demeanour during the cadetship. Instructors and administrators would be looking for that, right?
