I didn't have a purchasing certificate or purchasing experience, so I went to a pharmaceutical company to apply for purchasing. Is it necessary?

You don't need a purchase certificate in Hefei, the capital of Anhui Province, as long as your pharmaceutical company issues a purchase certificate. I wonder what other cities have proved. In fact, you have a great chance to study this major. You can tell people in the company that you are interested in purchasing. Generally, as long as there is a shortage of people, they will take it.
