Pros
There aren't a lot of pros. They have parties occasionally that can be fun.
Cons
You will not get paid what you are worth. The raises are minimal and aren't even a cost of living raise. The CEO will tell you the company is making a ton and they keep acquiring companies left and right, but they refuse to give you a decent merit raise. If you aren't an engineer, there aren't a lot of growth options. People will take advantage of you, especially the higher ups. There is a HUGE advantage to being at Headquarters in Rapid City. They have the bigger parties/birthday lunches that the company pays for, recognition, promotion, etc. If you are anywhere else, you feel left out when you hear about how much more headquarters does for their office. If you are remote, then you basically get no perks ever. If you want to continuously feel appreciated, look elsewhere. If you need some experience in the short term, that is about the only recommendation for working here.
