Pros

Experience working on multiple projects and opportunities in varying areas and fields. Schedule flexibility.

Cons

Rushing to get deadlines in will be the norm. Older technology for large software applications and no rush to update. Expect to teach yourself how to do your job much of the time due to busy management.
