Interns often collaborate closely with senior developers and participate in code reviews, agile sprints, and team meetings, gaining practical experience across the software development lifecycle. This hands-on exposure is designed to develop your technical skills and prepare you for a future full-time role.

Familiarity with frameworks like React or Angular, databases such as MySQL or MongoDB, and version control systems like Git is typically expected. Strong problem-solving skills, eagerness to learn, and effective communication help interns excel in team-based, fast-paced environments.
