NVIDIA Design Verification Engineer interview questions

The recruiter set up an online meeting schedule. At the meeting a higher level engineer is at the other end. He asked a few questions about my previous work. Then he gave several work scenarios and ask how to resolve the problems. The meeting lasts 1 hour. The second day I received an email they won't move forward with my application.

Recruiter contacted me in LinkedIn , I sent him my resume and HR contacted me asking for time slot for phone screen. This was the worst interview experience I ever had. After I shared my availability recruiter said the hiring manager will call you on this day at this time. I was expecting his call and none called. I sent an email to HR to follow up with the manager, she asked me to reschedule, they confirm the interview for another day. I was ready on time hiring manager called me ask to reschedule , I agreed for a later time on same day, I was waiting for his call he didn't call me. I sent HR another follow up email , I got a response from her saying hiring manger will call you shortly. After an hour I had a call from the manager and he asked, "Is this a good time for you" . I said I am busy may be after 45 mins we can talk, he said he will call in 45 mins. After 45 mins he called me. Below steps tells the process. 1) He explained 1 min about what he is looking for. 2) He asked me "you have any question for me" ?, as he wants to hang up after 2 mins. I dragged him into the interview question. 3) He asked me about my current role. 4) He asked me to write a code. I did write the code he said its looks good to him . 5) He said that’s all I have for you, you have any question for me ? , My question was : Next steps in hiring process. 6) HR will contact you. 7) Thank you. This all looks to me like they were wasting my all time , pathetic people.
