Pros
I've always found Fahrenheit 212 unique in that it employs extremely intelligent, driven people who are also humble, kind and don't take themselves too seriously. A generalization to be sure, but one that proved true far more often than not in my time there.
Senior management roll up their sleeves and set a tone of hard work and high standards from the top. The company is entrepreneurial enough for individuals to develop their own "platform" and launch initiatives to solve operational, cultural or training-related, and have that drive rewarded.
The firm's reputation is strong in the market and as a result, lots of interesting challenges from big-name clients come through, and access to the client C-level is not uncommon. Much of the company's work is hailed by clients not just as good, but great.
The office is gorgeous, the talent and culture are lovably quirky, and the holiday parties are epic.
Cons
The Capgemini acquisition has added pressure and complexity to many aspects of the company's daily operations and go-to-market efforts, but throughout it all F212 has still maintained its own brand, space and culture (all while still leveraging Capgemini's client base to grow).
Promotions can be limited in terms of specific times-of-year and slots available at the partner/VP level.
Work hours can be long and unpredictable, but such is consulting - it ebbs and flows.
