S&T SA Transition To Full Time Buy Side Trading

Will be interning summer 2020 at a medium investment bank (think HSBC/Deutsche/CS etc.) New York office. But eventually, I want to do trading/quant research at a top hedge fund. More info: Target school, stem, minor in real estate. Any suggestions on what skills to focus on over the summer/how to network/materials to study... essentially how to make the transition? I feel like the summer internship is not necessarily the most prestige on the street (in terms of leveraging the experience for future recruiting. Don't get me wrong tho, I'm very very grateful. Thanks in advance!
