Why don't recruiters return my chats?

Hr talked to you but didn't reply, which is probably your answer. He has received it, and you have answered the questions he wants to ask you. But if he asks you a question and he doesn't reply to you after you answer it, you can take the initiative to ask him what else he needs to know, and then communicate with him in time. Generally speaking, hr will communicate with us when we join the company. At this time, we must do a good job in the preliminary work and leave a good impression on the company and the personnel department.
