Is it possible for an individual(International applicant) possessing a valid CPL with 250 flying hours to apply CX cadet program?
You are way qualified for the AE stream based on your flying experience but keep in mind that the course is currently closed. No word yet when it will reopen. Your application will ultimately be put in a waiting pool, indefinitely.
And, how much success rate one would expect to get in to the cadet program and ultimately to a S/O position in CX for International applicants?
I don't wanna be sarcastic but what would be the point to ask for the success rate if you can't even get into the game? Unless you have a HKID OR an ICAO ATPL with 1500 hours your success rate would be, Zero.
