Pros
The small team meant that someone was always looking to share their work and teach the interns how to do a different job when the general workflow became lopsided. This led to tons of mentorship opportunities and a great introduction to the many facets of a small business. Steve gave a bunch of talks where he just talked through his story and Badger's story, which was pretty cool to hear.
Cons
The large group of interns (some part-time and some full-time) could be a little annoying. When any significant questions or issues came up in my work, it was unclear whether I should ask another intern for help/try and figure stuff out as a team, or just go to one of the regular employees. Without knowing how knowledgeable or experienced all of the other interns were, it was difficult to tell who was giving me good advice and who thought they knew more than they did.
