I had the same exact experience with him a few months ago. I didn't understand. I'm a American ESL teacher with University experience. He asked for my documents and I sent them. He then talked to me over the phone for a little while and said he wanted to hire me. I asked to speak with some of the previous teachers hes had and he gave me two references, neither of them were valid emails. I never heard from him since. I even SKYPEd him asking why I wasn't chosen and that I understood its a competitive market (LOL). He never responded. Hes a strange fellow indeed.
