Visa Inc. Software Engineer New Grad interview questions

They took forever and missed 2 interview slots. I had to re interview couple times. The first step was a hackerank, which I didn't get all correct but passed anyways. The second step was a 45 min interview where I got asked multiple Linux and Kubernetes questions as a new grad which didn't make sense as the recruiter said this part of the interview would be behavioral and not technical. Finally at the end got a system design question about building libraries for books or something similar. As a new grad was not expecting this again, rejected after this

Applied and got an OA on code signal. Their was 4 questions 2 leetcode easy 1 leetcode medium and 1 hard. Focus on finishing first 2 as fast as possible.
