NVIDIA Physical Design Engineer interview questions

one phone interview he was a lead of physical design explained his work and on what they are working on like clock synthesis, APR. He asked some basic layout questions too. Overall experience was decent. I expected a positive response, though i didnt. Gpa might be a factor in filtering out in initial rounds

The interview was hold during the info session. We talked about my previous projects and experience. Then they asked some technical questions. The question was not difficult but if you are a student as me, you need to review the basic stuff.
