I applied through college or university. The process took 1+ week. I interviewed at NVIDIA (Hyderabad) in Nov 2020
Interview
The panel was cooperative and willing to listen. Three people were in the panel. Individually they asked questions. But didn't include programming. Only theoretical and conceptual digital design questions. And about two aptitude questions.

I applied through an employee referral. The process took 4 weeks. I interviewed at NVIDIA in Dec 2020
Interview
The interviewer went through my resume and for some of the technologies I listed, such as Qt, he asked some questions in regards to possible implementations. Overall though there wasn't much more hardware related questions asked, mostly because I was doing software automation for the hardware team.
1 technical interview with 6 questions. 2 interviewers were present asking about my resume and qualifications. The rest was the same as any technical interview.
Emphasis was placed on VLSI design and embedded systems. Study the basics very well and it will be medium difficulty.
