Familiarity with development tools such as Git, code editors (VS Code), and frameworks like React or Node.js is often expected. Strong problem-solving abilities, eagerness to learn, and effective communication make an intern stand out. These skills and qualities are crucial for adapting to real-world development environments, collaborating with teams, and contributing valuable work during the internship.
