Capital One Software Engineer interview experience

Candidate report, summarized by Dataford

I went through a four-round format that started with system design and then moved into coding, behavioral, and finally a chatbot-style case review.

The overall length felt like a full day, and I spoke with multiple interviewers across the rounds—enough people that it started to feel like each person had a different lens on the same story.

The system design portion centered on building a banking application and required me to cover core account features, and then the coding round focused on file actions like creating, deleting, and copying files while reporting whether operations succeeded. After that, the behavioral questions asked for examples of challenges and achievements, plus a time I disagreed with a manager.
