NVIDIA interview questions

Nvidia came to our campus on 30th Nov for test and Dec 1st for Interview. Hiring process was done in two steps. First round was a descriptive test (1 hr) covering Digital Design, Cache concepts, CMOS properties, fault detection etc. Paper was pretty much easy, but a bit lengthy.

Three 45 min phone interviews. First was timing analysis intensive and went into a lot of detail about timing fix techniques. I was really really sleep deprived during this interview and we spent 20 min talking about the pros and cons of upgrading metal layers... Not sure how I passed this interview. Second was more comp arch focused but ended in more timing analysis questions, some of which were redundant. Third was with HM, half was just talking about potential roles and answering my questions, other half was about describing projects and some more technical problems, asked more redundant timing analysis questions. They really wanted to make sure I knew backend I guess...
