How can I go to a pharmaceutical factory to do QC or QA work?

I am an undergraduate in this major.

General pharmaceutical companies do not want undergraduates when looking for QA or QC. Unless you are excellent, you are competing with a master's degree or a doctor's degree. All they want are graduate students and doctors. CET-6 or above, should be able to understand professional English.

With relevant research experience, let me ask you about your graduation project again. Need to have long-term experience in laboratory operation and be familiar with most instruments. These are what ordinary undergraduates don't have, and of course there are strong people.
