Why do some companies always recruit people?

This situation generally has the following reasons:

First, the recruitment company didn't find the right person.

They will screen resumes submitted online and choose people who are suitable for their company. Not being selected is not necessarily the reason for the applicant, but it is not surprising that you don't reply when you receive your resume, and the quality of the people responsible for recruitment is also uneven.

Second, these companies reserve personnel information for some positions by constantly releasing recruitment information, which puts a little pressure on on-the-job personnel.

Third, by refreshing the job advertisements, it plays a propaganda role.

In short, when you meet such a company, just ignore him.
