I applied online. I interviewed at Maple Tree Education Centre (Lam Tin, Kowloon City) in Jul 2018
Interview
relatively easy but with a few tricky questions. They are some standard questions like "why do you want to teach these kids" but do prepared for tough ones like "What lesson plan you would make for these kids". The atmosphere was mostly relaxed and they surprisingly don't ask much from you such as needing to show your certificate(s).
Interview questions [1]
Question 1
Most of the answers were pretty easy to answer to though they were two tricky ones. They asked me about a parent complaining that I'm green because I have a lack of teaching experience. Another is to ask to how to develop a lesson plan on a speaking subject such as having dinner with the president.
