Background: I am a HK local residence.
CX had tech interview (initial interview) in 2011 but they have changed since 2012 because they want to speed up the interview process, i mean more candidates can go to stage 2. I am not sure what's happen outside HK, SORRY
Without a doubt, many people are stuck in ICAO English (except native speaker) after initial, so not many can go to final eventually.
In this year, CX would like to hire 400 cadet pilots (75-80 local). The HR said CX will still hire more cadet pilot in 2013.
Work hard and good luck, guys.
