NVIDIA Intern interview questions

They conducted aptitude test with 4 sections(data structures, c/c++, aptitude, operating system) and shortlisted students were called for Short interviews on c,c++, data structures and algorithms and problem solving skills.

I had 2 phone interviews. It was for a very niche computer science role. After the second phone interviewer, I stopped receiving any update from the recruiter. I later found out that they decided to move forward with other candidates who had never even done the required skill for the internship whereas I had research experience and even taught that skill at a reputed university. Thanks for humiliating me in this disgusting manner and wasting my precious time. Such arbitrariness is frustrating and depressing for me - I hope the company makes progress, but I am definitely never applying to NVIDIA again.
