Good Overall

The staff at Adventure Teaching did a great job getting me interviews with quality schools. They were very organized and informative for me on what to expect in Korea as an Ex-pat. Things in Korea are never as planned out, organized, and as well communicated as my experience in America, but as long as you know that then you can enjoy the spontaneity. Once I got to to my new home my boss took over for making sure I had what I needed, this isn't always the case as I have learned from others.
It took me a while to connect to other foreigners in my city only because I didn't find the local teachers facebook group for my city. In my city the foreigners do a great job of spending time with each other and looking out for each other. I have found the majority of Koreans to be very friendly, welcoming, and helpful as well.
Korea has been a great place to explore many places and is fairly easy to get around even without knowing Korean as long as you are not afraid to ask for and seek out help. I have gotten lost a few times or missed my bus stop a few times because I didn't know Korean, but the Koreans have been great at helping me get back to the right place.
Every teaching job is different and all have pluses and minuses. But over all Korea is a very easy place to work and live.
