Interview questions are straight forward. Maybe an ETOPS question, tell me the actions for a ground proximity alert, what are the actions for an EICAS message... Important thing is to speak slowly and as clearly as you can. Read the QRH about how a checklist and such is to be used as that is the correct answer. In Korea there is a question and there is an answer. The locals know both and as far as they are concerned there is no other way. Memorization is key.
