This has nothing to do with your settings.

First of all, a carefree future is different from Zhilian. It doesn't have the function of actively submitting resumes, so it is impossible for the company to contact you without submitting resumes. (Unless you are a high-end talent, the following possibilities may appear)

Second, if you register and fill in your resume at 5 1job, it will be collected by the system into the future worry-free resume database. Worry-free provides the headhunting function for enterprises. Enterprises can search in the database of worry-free resumes in the future and browse the searched resumes. Of course, there is no reason not to charge for doing business. At this point, they see no contact information and name on the resume. If the enterprise needs the talents searched very much, it needs to download this resume, and the download is charged.

To sum up, I don't know if you understand.

In this case, you can choose the highest degree of publicity in your resume settings: complete confidentiality.
