Capital One Software Developer Internship interview questions

Super day: first technical, then case, then behavioral interviews. Questions: 1) Design a credit/debit card system, OOP question. Use HashMap and LinkedList to cache. 2) Given an array with consecutive numbers, find the number that's missing. 3) Check if BST is symmetric. 4) For the case interview, eliminate unnecessary if-else statements and use a truth table to test your result. 5) Behavioral: What project are you most proud of? 6) Tell me about a time when you explained something technical to a non-technical person 7) Why do you want to work for capital one

It was pretty chill. I started with a 45 minute technical Interview that I didn't do very well on. Then went on to a easy case interview where we talked about digital banking. I finished off with a Behavioral interview which I felt I did really well on
