Pros
Cooper is a company where smart, creative people come together to practice their craft, learn from each other, and have a good time doing it. The environment is laid back, open and fun, with challenging projects and openness to always trying new things. Lots of personal support to grow, take on new challenges, and pursue what you're passionate about, and if you're into education, the chance to take and teach CooperU classes. There's a solid work-life balance. It's a great place to learn and grow.
Kontras
The perks/benefits are behind other Bay area companies, and the way projects are structured, it can be challenging for designers to get a break for vacation. It can be hard to know where you can grow to as it's a pretty flat company, and they seem to be slow at promoting designers into directorship positions. They need some new thinking and fresh blood at this level.
