NVIDIA Software Developer interview questions

I had 4 phone interviews, 1 full-day interview(with 6 different people) and a final interview with the department director. It was a very long process due to Covid but the recruiter was very responsive and helpful.

one phone interview, two onsite interviews after that an HT interview. The interviewers were good I passed all the interviews with the HR one. After that, the recruit ghosted me for a month with a minimum update. One month letter got a rejection phone call and telling me to follow up after two to three months if anything new pops up. I followed up two months after and got ghosted again, so decided not to apply again. no expected from a big company such as Nvidia.
