If so, I will handle it this way
1. If your organization is a small and medium-sized enterprise, it mainly depends on the person's business ability, and the actual business ability of the supervisor should be focused on.
2. If your organization is a large enterprise and has strict requirements for the qualification review of applicants, then after passing the key assessment on the actual business ability of the supervisor, you can ask him to go to your local talent service center for verification. The authenticity of the graduation certificate must be brought with the verification certificate issued before you can register.
