Pros
I've worked at CALIBRE for several years. The people are exceptional, and opportunities are available if you want them. If you're the kind of person who wants to get things accomplished and learn all aspects of the business, it's a great place to work. Ethical focus is not just lip service. The leave is generous, benefits are good, and the employee stock options are great. Internal training is widely available and frequently conducted by executive management. External training and most benefits are at least on par with the market. It is a steadily growing company; management at the executive level is careful, accessible, and thoroughly involved. It's a place where, despite 750 employees, you will likely be known to the C-level team.
Cons
This is not the best place if you want a predictable, 9-5 type job, and the culture is heavily driven by the fact that the majority of people are former military (can be a pro and a con). The pay is not the top of the market. You have to have an entrepreneurial mindset and reach for opportunities, and even with that attitude, advancing can be difficult.
