What should I do if I go to a training institution to interview teachers and don't tell me the results for several days?

I hope I can help you. I am also the interviewer of the training institution. Generally 1-2 days did not give you an answer, basically hopeless. If they call you to go to work for a long time, it's because they really can't recruit the right person to call you, so you don't have to go. You are a substitute, and there will be no good development. If you have the right person, you will be replaced immediately. This is a fact. Come on!
