I interviewed at Nvidia at Yokneam, Israel. The interview itself was fairly difficult and contained non-standard or trivial questions, including one that seemed more like a riddle than anything else. The interviewers themselves were either disinterested or highly critical. One was quiet almost the entire time, and the other was very judgmental and dismissive and wanted to control the pace of things. When a question was answered correctly, he would not openly acknowledge it and move on instead, and he was not above throwing fairly snide and unkind remarks and constant critisims over minutiae that were not really related to anything that were not really related to the content of what I was doing (e.g. He went on a random tangent about compilers for no apparent reason) and was prone to prolonged silences. Midway through the interview I was stumbling through implementation details despite having done everything correctly purely because I was recieving no positive feedback at any point and in fact did not know that my solution was optimal or even on the right track until after I finished things there and checked stuff on my way back home. I felt that not only was the interview itself not easy, but the interviewers made it harder than it needed to be. By the time I left the interview, I felt crushed and my confidence was shaken, which is not something that happened to me before.
