Capital One Software Developer interview questions

Three levels of interview process. Case study, technical and behavioral question. For the technical interview, I would brush up on basic data structures and algorithms and do at least a handful of problems on Leetcode. I did not find the technical questions too challenging. What threw me off most was the case interview, which is basically a giant linear algebra word problem.

I was approached by the recruiter via LinkedIn and till the interview process , recruiter was reachable and eager to answer emails/phone calls. Interview went fine but afterwards he literally ghosted. I don't know the feedback or what happened with my interview.
