Pros
This is a fun place to work, for the most part everyone on the staff is friendly (including management). My group is a phenomenally talented group of people who all work very hard. The benefits are on par with other software companies. Good daily perks of free fruit/beverages, weekly free breakfast and Friday cookies. Annual company wide weekend up NH, and a company trip every 5 years to fun sometimes exotic locations are something to look forward to. Year over year, the growth has been steady and constant even through the recession, so it's comforting to know your job is not in jeopardy when times are tough.
Cons
The salaries are sub-par with other software companies. It's not a place to make a career - great place to start and gain valuable experience, or to spend the last 5 - 10 years of your career before retirement. Trying to move up the ladder is nearly impossible, as upper management (who have all been here forever) continuously hold staff back. I've asked for promotion consideration numerous times only to be ignored.
