I was very optimistic and open minded when I started work here. At best, it could have been a place to retire. At worst, it could be a stepping stone. As things turn out, I have a stepping a stone... covered with sharp spikes.
All airlines are different and I'm not sure that describing what my conditions are like would be helpful information for you when checking into Seoul. One thing that I recommend for you to check out is the expatriate pilot turnover rate. If guys don't stay around for more than a year or two, find out why. Also, ask what training is like. See if everyone has stories about pilots they know getting fired or quitting before they even finish training.
