Why do many companies post recruitment information online and call them, but say they don't recruit people?

The first reason may be that the right person was recruited before, but the recruitment period for purchasing on the website has not yet arrived. The second is that the website refreshes the recruitment information of some senior members every day in order to make its data look richer, which also advertises them to some extent. The second possibility is relatively large.

To avoid this situation, you can go to some regional recruitment websites, such as Qilu Talent Network in Shandong. Recruiting units are basically local in Shandong, and there are few people who refresh the recruitment information. Only when the company logs in to the website on the same day will it refresh.
