NVIDIA Senior Verification Engineer interview questions

I applied online to this position as it seemed interesting. The recruiter got back after 2 weeks. Another two weeks passed as there were some confusions. Then the initial interview happened. It was tech interview with the lead engineer. There was no hiring manager as they are still looking for one. So it appeared they simply are looking to fill a position for future needs but not sure when. I think it was an OK interview but had good experience with the recruiter.
