Intel Corporation Software Developer interview questions

No unexpected questions, all normal embedded questions which are pretty common

HR phone screen is nice, HM politely reviewed my skill and ask some experiences, he said couple times I am best fit in several candidate screen. 3rd interview set by foreign born technical guy with accent. Nothing difficult, but he focused on many trivial questions, rude and frequently cut-off my answers. Most are chipset spec questions. This interview was very odd, he seemed mostly interested in demonstrating his own expertise in how familiar with chipset registers offset and bits function. I know these chipset features, but I didn't memorize it prior this interview. Those register bits are not notable and no need to recite everyday. Just open spec to get it in seconds. He questioned me many times, why I cannot memorize these registers address, it is very important blah blah blah.
