Familiarity with version control systems like Git, web frameworks (e.g., React, Express), and databases (SQL/NoSQL) is typically required. Strong problem-solving abilities, eagerness to learn, and effective communication skills help interns collaborate with teams and adapt to new technologies.

Interns often participate in code reviews, agile sprints, and team meetings, providing valuable hands-on experience and learning opportunities.
