Pros
Relaxed, laid back culture. There are a lot of different things you can work on throughout the IT department. The work-life balance is great. The campus is nice. This would be a good job for someone looking for stability.
Cons
A lot of the technology is outdated. People just do their job and not much more than that. There isn't much innovation, and you will likely work with many people who are lacking in skills and understanding of modern technologies and just programming ability in general. With many employees having worked at the company for many years in an environment of low-growth and hacking on badly written code, the problem of trying to transition out of outdated applications, let alone write decently-built applications is a significant effort. You are expected to work for at least a few years to be taken seriously. The culture and values that are touted seem to be contradictory to the general working environment. Although there may be a few teams working on some cool things, most of IT participates in dull work.
