Can I practice during my sophomore summer vacation? I'm learning java, and I've learned javaweb. Does the company have high requirements for interns? Has the interview been conducted?

"Summer interns" only recruit juniors, because some of them will become full-time, and they can't become full-time after the internship of sophomore, so there is no chance. However, daily interns can vote for their sophomore year in summer, and websites such as Zhaopin, Intern Monk and Dajie.com can submit resumes. Generally, there is no computer test for ordinary interns. An engineer may call you for an interview, or let you come to the company for face-to-face communication to test your level. As for the level requirements, it depends on what company you invest in. The requirements of first-and second-tier Internet companies are still quite high.
