Interviewed by three individuals, one Japanese woman and two American men. Not quite good cop/ bad cop scenario, but one was stern the entire time while another was more open. Spit fire questioning for about 25 minutes. If you come prepared (Google how to prepare for JET interview) then you should be able to anticipate most questions. I prepared about 40 questions ahead of time and only had one question that took me off guard. My general advice: you cannot prepare too much. Come in knowing some Japanese even if you put zero on your application. Dress professionally and conservatively. It is definitely expected of you. If in doubt, just smile. Even if you are nervous. I still have a month until I hear back, but I think I will receive an offer.

Smooth. Interviewers were kind. Asked questions about why I wanted to join, asked me some questions in Japanese, asked about ways I could contribute as an ALT, and that was that.
