Pros
Benefits are great, pay for the area (depending on your area) is great, career mobility (while incredibly team dependent) can be great. Cafeteria food and people are generally smart and enjoyable.
Cons
Knowing what I know now, I would have never joined Capital One. Capital One's culture has taken a turn for the worse. Cutthroat performance management cycles has made the company a political nightmare, with each performance cycle seemingly getting worse it's apparent if you don't have the support of your manager, you'll find yourself out of luck at some point or another. Working here was once enjoyable and felt like everyone was working towards a common goal but now, politics and headcount requirements have turned joining this company into one of the biggest regrets I've ever made. High favoritism is placed on the college grads who enter the Capital One rotational program fresh and unexperienced and if you join the company professionally, you'll find your onboarding nonexistent, your expectations unreasonable high, and your salary quickly being bypassed by new hires who have little value to immediately contribute. It's a frustrating space and I've watched many good friends and employees enter the rotating door, either PIP'd or pushed out and several steps behind in their career because of it.
