Capital One Software Developer interview questions

During the four hour back-to-back final interviews, I was interviewed by men who kept cutting me off to state the answers. It felt like they were impatient to get through a list of answers. Very little diversity in the interviewers and rarely a second interviewer to lessen bias. The online online interviews didn't have a break and what I was actually technically interviewing for was the last one, at which point I was mentally exhausted. I’ve had back-to-back interviews with more flexibility and dialogue to tackle questions. They seem big on system design and DS & A questions.
