I might be able to help!I applied to Seoul EPIK from another MOE a few years ago and got in.1. Contract officially starts March 1 and ends on February 28. I didn't have any problem with overlapping contract timelines. Rather, I had a few days in between contracts to attend orientation and move up to Seoul. I'm not sure if experienced EPIK teachers need to attend orientation anymore.2. Myself and other teachers who transferred renewed our ARCs once we got to our new schools in Seoul. Might be easier just to wait and do so when you get here since you'll be changing your address.3. Yes, no renewal bonus and your housing deposit is more expensive (1 million Won). Schools seem to be more strict about camp up here as well. In my old MOE, teachers would have three day camps and that would be fine. In Seoul, people tend to do the full week and half-week camps are typically unheard of. I don't remember the camp requirements from my old MOE, but in Seoul teachers are required to do 4-5 weeks of camp in their contract year.4. I applied in September (for the February contract) and heard back my results in early December. Didn't exactly apply on the opening day, but still early on. The interview process was different from my initial EPIK job and was more a formality and checklist of documents I'd need. I had one year of experience with EPIK under my belt when applying, though there were plenty in my first Seoul contract year who were entirely new to Korea and ESL.Best of luck!
