Does New Oriental English teacher have to go through several months' training before taking up his post? And the training period is unpaid?

Yes, I am a trained New Oriental teacher like you. In fact, the most important thing in this interview elimination process is to watch you attend class, so if you have teaching experience, you can calm down, because most experienced teachers can see it, so New Oriental will give priority to admission. After all, it also hopes that you can attend class as soon as you come, and it also hopes that you can get started quickly. But if you have no experience, you'd better take a few more classes these months to improve your actual combat ability quickly, that is, you can get the ranking. ~ Come on, colleagues!
