Pros
Local Austin company with many highly skilled and experienced consultants that seem to share a passion around software requirements. I had the luxury of meeting some really great people while working there. Office atmosphere can be a little hokey at times, but they tried hard to make it fun. Seilevel has good intentions to be a great niche company and do believe they still can. There will always be a need for good software requirements. Decent vacation time, but it also includes sick days and personal days. Seem to be concerned about work-life balance. Your voice can sometimes be heard.
Cons
It was always very dificult to understand the direction and intent of upper management. Very disconnected to lower level employees. Today we are going to do things this way, tomorrow differently, and the next day we'll go back to how we were doing it initially. Upper management is extremely intelligent and if you are not equally as smart, then you are basically very stupid (at least in their eyes). They have their favorites for projects and if you play your cards right, you might be chosen to lead a project even thought sometimes the leader is not capable of forging ahead and ensuring project success.
