Pros
A decent part time job for a student. Doesn't require too much of your time outside of classes and is flexible to your class schedule. Worked with other students(developers) and was usually a easy going work environment. Also a good way to work on craft using programs, such as the Adobe Creative Suite, outside of classes.
Cons
Lacking creativity. No one I worked with had a good grasp on the importance of design or the work that goes into it. Developing is definitely more of the focus, with design an after thought. Cookie cutter layouts for clients with little to no creative input on each project. Never met with clients or got a chance to talk with them on what they were looking for. I was just always given an assignment each day to create icons or buttons for their designs, not involved with the design much at all. In my experience, management never understood the creative process and didn't value attention to detail. I was always told to just get it done as quick as you can, and if it looks bad, it will be fixed later. The quote I always remember is, "We aren't making the Mona Lisa here." If you are looking for a design job to explore your creativity and get some valued experience in the graphic design field, this isn't the place to do it.
