Pros
Capco is by now (late 2014) the largest global consulting firm in financial services, considering the number of consultants they have in FS (nearly 3000 globally, almost 1000 in North America) which is more than any of their competition (including the Big 4, Accenture, etc) once you strip out those other firms' non-FS practices and Services (ITO, BPO) etc. Capco has experienced 25-35% growth each year since 2010, and there is a reason for it.... People are coming to Capco from the traditional consulting firms and from banks for one singular reason -- the culture of Capco is fantastic. There is no other firm in the FS industry that is more innovative, invests more in their employees, or has less bureaucracy and unnecessary structure. It feels like an entrepreneurial startup, even though it is not so small. Capco just held a 3-day employee gathering in Puerto Rico at the incredible El Conquistador resort. They flew down over 800 employees. The event included incredible speakers such as Peter Diamandis (X-Price founder and voted one of the 50 most influential people in the world) and parties that were legendary. People came away amazingly inspired, energized, and passionate. No other firm would do this! There is a huge focus on innovation and transformation. Employees are actively engaged and encouraged to come up with ideas, and are given support to do so. At Capco, no one will hold you back.
Cons
The very rapid growth has caused some issues. Internal systems and admin are not the best, but management are working on it. The other issue is that they have taken on some client work that is not to everyone's taste, like testing or project execution without much chance for employees to shape the strategy. Some people like that kind of work, but others (like me) would rather work on making a real difference for the client. Management is open about the challenges -- on one hand Capco has built a fantastic business, growth and consulting model based on long term client commitments, on the other hand they are well aware of the issues it causes some people and are actively trying to fix it. Things aren't perfect. They aren't at any firm. What I really like about Capco is that management is very open about the challenges and engage employees about the best way to solve them.
