Why are many recruitment information in the post bar unclear?

Hello, the current post bar is not the previous post bar. Many people have a strong purpose on it, either cheating or draining. And as far as I know, normal enterprises will not post recruitment information on the post bar, so I suggest you don't trust the recruitment information above. If you want to find a job, it is safer to go to a regular recruitment platform. Because you also found their doubts, this is not the normal recruitment behavior of normal companies, beware of being deceived.

If my answer is useful, please adopt it. Thank you very much
