Vantaggi
Very practical experience for package design (both graphics and production) and social media. 9-6 days, usually no need for overtime. Modern intern dormitory near the office that creates a community among interns (in fact, I'm still friends with some of my teammates years later). Modern office with free lunch every day. Lots to do in Greenville, Rockwall and (a bit further) Dallas if you have a car.
Svantaggi
High-pressure corporate environment. Often unreasonable turnarounds and revisions (since graphics is the last link in the chain before production). The periods leading up to trade shows can be especially hectic. The few times my team worked overtime, we were in the office until midnight, and it was a thankless job. Internship contracts are 2-3 months long, and depending on the time period, your department may not be looking to hire full-time. Micro-managing, feelings of constant surveillance, and occasionally even condescension.
