Capital One Software Developer interview questions

After applying through my college's career fair (in the Winter), it took around 2 months for them to email me about having an on-campus interview. They sent me exactly what to expect in the interview through an email. There is a Case interview (a problem experienced by Capital One in the past), a Behavioral interview (discussing notable experiences from your resume), and a Technical interview (2 coding questions, probably easier than most Leetcode Easys and a high-level design question). Each interview was with a different person. Within a week, they gave me a response regarding how I did during the interview (which unfortunately was a no offer). The interview experience was relatively laid-back and definitely not hard. I probably didn't get the offer because my coding question portion was relatively slow (for pretty easy questions) and I stumbled a little on describing my experience in the behavioral section.
