Hello. I got hired directly by Korean air. I do not have Korean citizenship but I was born in Korea and I speak and read Korean.
Currently, Korean air does not operate cadet program anymore. Instead, they are hiring 1000 hour plus pilots with University degree under 40 years old with CPL MIFR with ICAO English rating level 4 or up. All the hiring process is done in Korean. and since this is for the local Korean guys, they do not provide tickets nor accommodation. About half of the applicants were from USA and Canada. No one was competing for each other but the success rate is not that great considering there was no competition. They are hiring but not too desperate right now. Interview questions weren't that bad but if you haven't flown a jet or studied ATPL stuff (not FAA or TC - these wouldn't help - too easy) it is quite hard.
You can apply though

Good luck
