After submitting your application, you get contacted for a first 'interview'. In reality this is just an orientation meeting with a couple other candidates, with a group discussion tacked on at the end. This is your first chance to actually speak and I guess they're looking for enthusiasm, general knowledge, your general level of English and for you to show that you know how to toe the line. If you pass, you get invited for a second interview. This is the actual interview. Most of the questions are rehashes of the application you filled in, so as long as you stay consistent on it, you should be fine. After a while, I had to do two roleplays. The first one was where I had to introduce myself in English to a class of junior highschoolers. The idea is to elicit a response and get some dialogue going as opposed to a monologue. The second roleplay was teaching an elementary school class a song of your choice with the idea of teaching vocabulary. I chose head, shoulders, knees and toes as most others would I assume, given that it's the easiest to do and teaches vocab nicely. Afterwards, they'll tell you they will be in touch in a couple of business days with their final decision.
