NVIDIA interview questions

I got phone interview. They asked me projects on my resume. digital design, verilog and other things. But the end, they start asking me data structure........hash table, binary search tree. I told them I did not review any programming because I thought I was interviewing for a hardware position not software.

Had 4 interviews 2 on phone and 2 personal interviews. Both the phone interviews were very technical covering topics from CMOS process, STA, ASIC flow, Low Power techniques.
