NVIDIA interview questions

For interns generally they conduct 2~5 phone interview based on the skills of the candidate. I had 3 phone interviews once a week apart. In my first interview, interviewer was asking more bringup related questions but as i did not had any experience related to bringup he asked me more programming stuff and i believe he might have recommended for another interview. Following questions:- -FSM -Computer architecture -Puzzles -Digital logic questions
