What certificate does the factory need to hire an electrician?

The factory needs electrician's "Low Voltage Operation Certificate" and "Professional Qualification Certificate" to recruit electrician.

Operation certificate: It can prove that the applicant has the basic skills and common sense of safe operation. Employers like to recruit employees who are skilled and can go to work when they come.

Vocational qualification grade certificate: it proves the technical level of the candidate, and the recruiting unit can see whether it is the technical level needed by its own enterprise. For example, if you want to recruit a senior worker, you must not recruit a junior worker. The technical level of a junior worker in a post is enough. If you come to a senior worker, the salary will definitely be higher and it is not economical enough, so you have to give up.

Graduation certificate: it can prove whether the applicant is a major or not, and the positive superiority of studying this major is much higher.
