How to treat the black-box operation of open recruitment by employers?

I think this is against the principle of social equity. Although the open recruitment of these companies is a process, it is necessary to carry forward the burden. Because these units are usually enterprises and institutions, not under the control of a leader. They need to go through certain procedures to meet the requirements of the procedures, otherwise it will be very troublesome to check. I think this is still an imperfect social system and the supervision of relevant institutions is not in place. I think if an enterprise or institution wants to become better and more efficient, it needs to establish a system of eliminating those who are competent and those who are mediocre, so that the whole unit can accomplish its tasks more efficiently.
