Pros
Good pay, interesting work, insurance is good. When I was there lots of really smart people.
Cons
I left arbor about 2 years ago and was pretty happy to leave. Definitely a caste system in place between support and engineering. Because of this it's a fairly toxic work environment if you're not on the engineering side of things. I also noticed the folks who were into playing politics got the promotions, such a waste from when I started with Arbor. Because of this you have folks who barely have an idea technically (think power point jockeys who try to be technical but aren't) being put in charge over technical folks (when I was there this was more the exception on the engineering side of things). The other thing to be aware if is career growth is really limited. On the engineering side of the house it looked like there was some room for growth. But elsewhere there wasn't much
