NVIDIA QA Engineer interview questions

There were 2 interviewers. They asked about my background, grades, why am i interested in this role. After that they gave me 2 logic questions (which i'm not sure how it's related to qa).

Went through 3 separate 45min interviews with different members of the team. No phone contact from the recruiter at all just email. Was rejected with a cookie cutter auto generated email. No explanation as to why I wasn't picked.
