Pros
Pay and benefits are generally pretty good for the area. Tech stack is relatively modern. You'll get some relevant hands on experience here.
Cons
Everyone here has mostly mentioned it already but the PIP culture is pretty bad. 10-15% of the workforce is fired every 6 months. This leads to the exact kind of work environment you would expect. Your ability to play politics matters more than anything. If you aren't able or willing to play the game you will be managed out. Most of leadership and a good majority of the engineering staff are all Indian nationals. If you do not belong to this group you will have a more difficult time fitting in and succeeding come performance management time. Things like taking off for medical emergencies or using parental leave will affect your rating and increase the likelihood of you getting pipped as you are in constant competition with your peers no matter what. All in all I would stay away from Cap One unless you really can't find any other work or just want to work for a year then grab a severance package.
