Does Guodian Nanrui only recruit fresh graduates?

This will not happen. Guodian Nanrui is a big enterprise, and all kinds of talents will be introduced. If you only recruit fresh graduates, you are inexperienced. Don't just train them. This is not in line with the normal development of enterprises. You can go to Yangzi Talent Network and have a look. There are some real-time recruitment information in it, which should be useful to you.
