NVIDIA ASIC Design Engineer - Intern interview questions

I was selected through a college campus fair event, where they selected my application based on answers given for set of design questions. I answered 3 phone interviews spread out over 1.5 months. HR would mail me, asking for availability over 2 weeks time. The hiring managers and HR are very prompt and helpful.

Applied online, received mail from HR to setup phone interview. Was asked technical questions related to FIFO implementation. Rest of the interview was on the projects I have done. The questions on FIFOs was related to the cases handling overflow of packets and also deciding the size of the FIFO, also what should be the size of the buffer if there is a leak in the system.
