Some recruitment companies copied all their documents even if they didn't know whether they passed the interview. What cats are there?

General unit interview, only to the final decision to hire you, inform you to come to work, will ask for a copy of your certificate. Such as academic credentials, ID cards and so on. I am now working in Xue Xin College. Recently, the college is also interviewing people. Usually we just leave other people's resumes. No one else will be notified. So, in this case, you have to be careful. Don't give it. Regular units are not like this.
