Pros
I am currently a full time undergrad student and an intern here. StepStone has hired multiple interns in different departments. Many of the analysts and senior analysts are only a few years out of college (in their 20s), so the work environment is more casual and not intimidating. Everyone here is friendly and happy to answer questions. The interns sit together so it's easy to chat with your co-interns who are closer to your age. Side note: the kitchen pantry and fridge is well-stocked with a variety of snacks.
Cons
I am only speaking as an intern of one department, but overall, the internship positions are very structured (read limited.) There is not much of an opportunity for interns to take on other responsibilities besides what they were hired on for, and the work is incredibly repetitive and to some extent, mindless. It can be a great learning opportunity if you wanted to learn more about the private equity market. As an intern with such a limited range of tasks however, I felt my learning curve plateau after maybe 3 weeks, being so pigeon-holed into the routine motions of quarterly reporting.
