Avantages
Decent salary and benefits, nice, sympathetic people, flexible working hours. How interesting the job is depends strongly on the team you end up with. Unfortunately, some of them are really dull. Good if you want to get the feel of working for a big, serious software company and learn some tools associated with it.
Inconvénients
While there are many great new projects starting at all times, there are also many positions aimed mostly at maintaining legacy systems and bugfixing. That, for me, is really boring, so I decided to leave. Also, there isn't much place for self-improvement or making a big career. People stay in one place, attached to their systems and technologies. If it's your first job, it should be good for some time. If, however, you're looking for a challenge, you can try searching through some of the more exciting opportunies, but you're probably better off elsewhere anyway.
