Pros
The pay is great and the benefits for Interns is great. Over the years I have had the opportunity to network with many people in the company.
Cons
As an intern they treat you as if you were a full time employee. Usually that would be fine except interns are typically only able to work 20-25 hours a week plus we have 16+ credit hours that we have to do for school. It has been difficult to get time off or even to leave early 30 minutes one day because they treat the time you are at school as your "time off". In many department interns are brought in with little to no guidance on what they should be doing and how to improve their skills. It is also not very common to see interns move to full time positions and it is difficult to move departments.
