Experience with version control systems like Git and familiarity with API development and frameworks are common technical requirements. Strong problem-solving abilities, effective communication, and a willingness to learn help interns integrate smoothly within development teams. These skills are crucial for building reliable backend services, collaborating with peers, and adapting quickly to new technologies and workplace expectations.
