Pros
There is a ton to learn here especially if you are interning with not much prior experience. The people are great to work with and are always there to guide you. The environment is great to work in and you begin to feel like the people are not just co-workers but are more of a family.
Cons
In the 3 month internship I had, I do not believe I had any issues or any complaints. Given that this was my first internship, I don't really have any other internship to compare this one to either. If you do have any issues, there will always be someone in the office to help you out and point you in the right direction.
