I think that more than learning about CS, I learned how to cope with enormous amounts of frustration that comes with being a dev and I also felt great when I was being challenged with actual deadlines through exams, hackathons, assignments, practicals and tough professors.
Professionally, I think the great knowledge of fundamentals of CS helps a lot and it is just a great way to get your foot inside the door (for internship interviews and career opportunities) of a company and then show what you're made of when it comes to being a dev.
Also, I had the time of my life because I was around like-minded people who loved the same things and it was good to watch them suffer at first and then, watch them succeed at something that I was about to do.
