Pros
Because software is Intuit's bread and butter, they respect and value their engineers and architects, unlike some other non-software companies. Although there is some drudgery, for the most part the work is interesting and there are opportunities to learn new things. It is a comfortable place to work and the stress level is lower than most other places I have worked. For instance, it is unusual to have to work evenings or weekends.
Cons
Sometimes the large company culture can be a little impersonal. The way each project is managed is really up to the individual managers, so your experience can be quite different, depending on what project you are on. Some are wonderful. Some are awful. There isn't a lot of bleeding edge work going on, if that is what you crave. In an effort to recruit new talent, sometimes they treat their interns better than their employees.
