Pros
Renowned company. A lot of great people work here.
Cons
There are 3 pretty big downsides to working at Capital One as a SE. The first is that there is no DEV environment, which means backend teams are constantly pushing experimental code to QA. This frequently takes down the QA environment, which directly impacts frontend engineers like myself. As a result, most of my day is going through Splunk logs trying to figure out which API went down, and tracking down the responsible team on Slack, which leaves me with little time to do my own tickets. The second is the unfair promotion and PIP system. Everything happens behind the scenes, and there is zero transparency as to who got promoted and why. I can't help but feel it frequently comes down to who's your bosses "favorite" as opposed to actual performance. The final is the PIP (i.e. being let go) system itself, which is based on stack ranking. Combined with the PIP system, it creates a toxic environment where no one wants to help each other due to conflict of interest (and a risk of being let go yourself). Overall, working at Capital One is not good for your mental health, so I would recommend working no more than a couple of years, put it on your resume and move on.
