NVIDIA Hardware Engineer interview questions

Three rounds of phone interview. Each interview lasted 45 minutes and all of them were very challenging. They tested everything listed on my resume and I also had to describe quite a few of my graduate level projects in detail.

I applied for the summer internship and had the three phone interviews. The first and second interviewer were technical engineers, and the third should be the group manager. Each interview was about 45 minutes. They asked several technical questions and then asked you to introduce the project in the resume.
