Familiarity with tools like Git, databases (e.g., MySQL or MongoDB), and frameworks like React or Express.js is typically expected. Strong problem-solving skills, a willingness to learn, and effective communication set standout interns apart. These skills and qualities are crucial for contributing to projects, adapting to new technologies, and collaborating successfully within a development team.
