Haier recruits people on campus, but why don't workers recruit undergraduates?

After laughing, although I don't know what you mean by Haier, I can see from the literal meaning that you are going to step on the hidden rules;

Workers are generally recruited as technicians. A technician is someone who hasn't graduated from college. If you have a relationship with them, you won't mix with them. You are two people from different levels. If you can't talk properly, you will have a bad relationship, which will lead to mutual contempt and greatly affect the working environment.

How does a recruiter get people from two different classes to work on the same platform? This is the hidden rule of society, and if it is violated, it will be abandoned by society.
