Autumn Internship 2021

I really liked the concept where all of us worked together, while using Scrum. Also, we learned about good practices that are different and more realistic than the ones taught in college. Perhaps the most important part were the connections that were created, both among interns and employees/mentors. It was really a pleasure to work and hang out with everyone.
