Pros
Capital One has a strong culture of "Excellence and Do the right thing", providing a great work environment to develop and hone critical competencies, numerous development opportunities (large and small projects), while also understanding and promoting the balance between personal life and work. It has been a great place to work for many years while I've progressed in many ways; I highly recommend working for Capital One.
Cons
While working here for many years, our benefits and compensation felt like they were exceptional early on, but with the purchase of other banks they have been decreased in order to provide standard benefits across the board. This, I'm sure, has occurred in many other corporations, but it would have been nice for the 'Maverick' of the financial industry to buck the trend and keep the high level of benefits and just extend them to new banks and employees.
