I know my uncle has just retired from KAL after serving them for 11 years and he has discouraged me to go for KAL. He says even if you pass the interview/med/sim, their line orientation training is very difficult as they dont like foreigners and there are chances they put you down after a period of six months of training. by this time you loose your previous aircraft recency and also the training cost which u have to pay.
you think about it before u go.
