Non-Target Sophomore with 2 Internships looking to land a bulge bracket offer by graduation

I am a rising sophomore with a 3.88 GPA and a decent SAT score (2100+). Due to my lackluster high school GPA I am currently attending a non-target university in the New York City (St. John's University, Fordham University, Hofstra University) because I was denied to NYU Stern and U MICH Ross. So far, I've managed to gain two internships this summer, one of which was merely data entry and fetching coffee for a hedge fund capital raising firm that didn't seem too successful, and a PE firm where I actually got exposure to deals and modeling. Besides transferring to another school, could someone give some advice on how to eventually land a bulge bracket offer come graduation.
