Most teachers find work through a recruiting agent.
They take your information and give it to schools who they have contacted or have contacted them in which you might like to work. Next you attend a job fair in which the human resource personnel from the school come and interview candidates who are interested in working in their school and country. This takes place over two or three days and you might have a lot of interviews or very few. Contracts are usually offered at the fairs or very soon after. If you get a job some agencies expect more money from you.
