You may work with technologies like JavaScript frameworks (e.g., React or Angular) for the front end, and languages such as Python, Java, or Node.js for the back end. It's common to collaborate closely with other developers, designers, and sometimes product managers, gaining exposure to the full software development lifecycle. Interns often participate in code reviews, agile sprints, and team meetings, providing valuable hands-on experience and learning opportunities.
