Is biomedical political examination strict?

Biomedical political examination is strict. The political review of pharmaceutical companies is like this: when joining a pharmaceutical company, the pharmaceutical company will require the entrants to issue a certificate of innocence. When issuing a certificate of no crime, if the employee has a criminal record, it will be found out. Now, no matter which way he joins the job, the employer will conduct a political review and there is no criminal investigation. If a job seeker has a criminal record, he will be found. Therefore, we must obey the law.
