NVIDIA interview questions

Got a call for a new position. Referrals might have worked. Position was very interesting. Had 2 phone interviews followed by on-site. Interview was tough, but not unreasonable. The diversity of question types is hard to prepare for. Open ended architecture questions, programming questions and testing of various concepts.

I applied in January,2014. Got a call after 2 days. Initial interview was formal introduction. They set up a technical interview a day later. Questions: (1) OpenGL pipeline (2) Draw triangle in openGL, texturing (3)Shaders, GLSL (4)Basic C++ , Array vector difference, data structure.
