Pros

They do have pretty good benefits such as, increase in time off every year, federal holidays are time off, stock options, healthcare and matching 401k.

Cons

The salary is not enough for MA and needed a bachelor's degree. There is little growth and they do not like promoting people because they know after 1 or 2, they will leave for a job with better salary and more growth opportunities.
