For those of you going for the interview, had one last month for the NG...
Medical was pretty thorough, they did some tests I didn't know existed.
Sim was fairly straightforward: Normal T/O, followed by VOR approach, all on AP, visual above the minima, then landing with crosswind. EFTO, back for SE ILS and GA, finish with vis circuit. AP can be used pretty much all the way through. RTO, and that's about it.
Interview was low keyed, important thing I was told was to speak slowly and clearly. Why do you want to work for Korean, what do you know about Korean etc
I learnt a few Korean phrases, 'Good morning', Thank you etc etc. They seemed to really appreciate that.
Got offered the position about a month after.
Good luck!
