NVIDIA interview questions

IO Budget / Timing: Since I was out of touch on this topic, I was not very well prepared on this. But I think I handled it well Also, was surprised to see a question like: How many ping pong balls would you need to fill up a 20X20 meeting room? etc. The idea was to see more on how I'd approach the problem and not necessarily give the right answer.

Questions on reflection coefficients, return loss, insertion loss, return currents in PCB, EMI concerns, etc.
