Pros
The company runs on the backs of some great people doing their best to keep things running. There are some really awesome folks to work alongside.
Cons
Mastercontrol is a study in how the "We are a family" attitude can be toxic. The Technical VPs and Directors actively work against quality engineering and quality of life improvement. The direction and focus of the Product Leadership is out of touch with engineering direction. The ability of managers and directors to lead they groups is highly variable and very disruptive. They have a habit of promoting people for their time and not their skills with Senior Engineers having skills that are completely misaligned with the role they are in. The all hands meetings usually involve lots of yelling and full production videos of the executive staff acting out skits. Take that for what it's worth.
