Capital One Software Engineer Data Engineer interview questions

The whole process was pretty long: 3 back to back 45 minute interviews. There was supposed to be one behavioral, one technical, and one case (yes, they did a case for a technical position). The behavioral portion, however was more technical in the sense that the interview asked technical questions (not problem solving ones, just questions about how things work). The technical portion was pretty generic, with a linked list question, a design question, and a SQL question. They send you prep for the case, but it essentially reasoning through a business problem.
