Advice
This internship really is what you make it. The guy sitting next to me did SF entry all summer, while I was building client facing decks, sitting in on MMs, building market maps, creating live / non-live updating excel models.
They also will tell you, you do not have an opportunity to work with Camber (PE firm that is G2's sister Co.) but if you prove yourself and express interest in Camber style work, you can get experience at a PE firm focused on turning around distressed companies. (two of the four interns including myself got Camber work) Camber and G2 are two different entities so you can add Camber as a second internship.
