Why do I take the initiative to send my information to headhunters, but headhunters don't communicate with me?

This is divided into several situations:

In fact, many private messages sent by headhunters are not sent manually by headhunters after reading your resume, but are automatically pushed by the system according to keywords.

Headhunters don't communicate with you: A. After a quick glance at your resume, there is no position matching you in the enterprise they are currently cooperating with, so they selectively ignore B. Headhunters themselves, as a third party, have changed their job requirements with the changes of the enterprise. It is very likely that the position has not been recruited and has not been deleted in time, so it is only the talent pool reserve of the resume at this time.
