Pros
FICO has far more going for it than credit scores. It is a leader in predictive analytics, and participates in a wide range of related markets. This means a lot of really interesting products and projects. FICO draws really smart and engaged people. It is a hard-working place, but very "grown-up" with strong respect for life outside of work.
Kontras
FICO's offices are very dispersed geographically, with three in California alone. Project teams are frequently spread across the globe, which means lots of conference calls, and some demand for travel, although that might be seen as a plus. The wide range of activity across markets and products means that getting extended attention from senior executives can be challenging, although the flip-side of that can be lots of autonomy.
