GitHub offers a 10-week paid internship program during the summer of 2019 at their headquarters in San Francisco, welcoming students from various educational backgrounds, including international students. The internship provides an opportunity to work on real projects alongside experienced GitHub employees, known as Hubbers, and offers a collaborative and supportive environment. Past interns, such as Srinjoy and Bex, have worked on projects like GitHub Classroom and the open-source framework Probot, respectively, while also engaging in activities like writing blog posts and conducting workshops. The program is highly praised for its enthusiastic culture and unique perks such as having dogs in the office. Applications for the 2019 internship program can be submitted directly through GitHub's website, with options to receive updates on future opportunities.
