Why do job fairs need practical experience to recruit fresh graduates? Isn't it stipulated to practice in high school? Where can I get practical experience?

No, you can practice every winter and summer vacation. We require you to practice for two weeks every summer vacation from your freshman year. Now many enterprises, especially good enterprises, attach great importance to this aspect, including your communication and coordination ability, execution and so on. There are still some differences between children who have practiced and children who have not practiced. People who have had practice will be more mature in terms of vision and the combination of professional knowledge and practice, but what you said is also reasonable. Enterprises without compulsory internship experience can be considered.
