Pros
Base2 is a solid, mature, no frills and no bs place with experienced people who have been around the block and know their stuff. I couldn't care less about having florescent bean bag chairs in the office or a clown troupe show every Friday... I want to do good work and get the job done and go live my life, and Base2 is all about that. There are perks like free lunches, stocked kitchen snacks, company parties, that kind of thing which I appreciate and enjoy, but more than that I appreciate them putting their money into their employees - like bonuses, training, not letting people go even when they're on the bench, sit-or-stand desks (a recent addition), improving the benefits package, etc.
Cons
I honestly have no complaints. It's easy to make a wish list of stuff you'd like, but there's no substitute for owners/execs/managers that genuinely want to do right by their people and go about their business with that in mind.
