Very informal interview. In fact it was hardly an interview at all. It seems that they don't like if you're too good of a candidate, but they're often desperate and that's how a qualified teacher with a CELTA like me actually made it through the cracks. Honestly, all you need is a good reply to 2 questions: 1) Why do you want to live in Ukraine? 2) Why do you think you'd be a good teacher? If you get those 2 right, you're in.
