NVIDIA interview questions

It wasn't clear what team or position I was being interviewed for. The first two phone interviews were good and were with people from the computer architecture team. The third interview was with someone from the PP team. The third interviewer kept asking me recruiter-style questions in addition to a rapid fire list of technical and brain teasers. There was no opportunity for me to express my views or ask questions--truly bad sign of group dynamics. He was also quite condescending.

I apply via hiring agency. They provided preliminary test which contain basic graphic related questions (Such as resolution, shadowing, textures) which you should answer online. Next day after preliminary test I received a phone call to arrange on site interview. On site interview is good, they give some time to rest before actual interview and than they start asking general questions (ice break). After that interviewer start asking technical questions. Questions are not difficult but you have to prepare. Some math questions. Graphic and pixels questions (Transparency, decals, shadowing etc) Interviewer was extremely friendly and helpful.
