Applied to nvidia about 45 days back, got a call from the recruiter within few days, they setup the round 1 interview.

• The questions asked were mostly on the previous work done. Some pretty simple questions about the system design and scaling ML systems.
• Answered everything correctly, though to me the interviewer seemed very distracted and uninterested from the beginning of the interview till the end, he was continuosly working on something else and did not had any focus on the interview.
• I felt it was a total waste of my time with this behaviour.

Got a call back after few days that the application did not move forward. To be honest i was relieved :D, if this is what the AI teams are in Nvidia then it is an utter dissapointment.
