Some websites have services that let you post your resume so it can be viewed by recruiters and employers. Personally, I would advise staying away from these websites until you have tried each and every other avenue. It will surely flood your inbox with several job offers of dubious quality and you'll most likely be subscribed to a number of pesky mailing lists. Nevertheless, should you feel like you aren't finding results from the other two methods, posting your resume can open some more doors for you personally. For better or worse, the times of posting your resume and jumping on a airplane are long gone. But getting a job in Korea teaching English is still pretty easy if you go looking in the right places.
