NVIDIA Software Engineer Systems interview questions

The company people had come in our campus. They looked quite flexible with their dressing, communication and work culture. All they wanted was good people to work with. Also the HR told his experiences about the company. At first we had a ppt showing what's the company all about and different sections. Then we had a MCQ test consisting of sections like C&C++,OS,DS and Quantitative Aptitude. Then followed by 3 technical rounds and a final HR round each of which lasted around 45 minutes to an hour.

applied for a co-op position through the university. challenged with an initial phone screen, follow up phone interview with manager. have interviewed with various teams for this company and it seems there are random engineers who are asked to take on the interview process with no consistent areas of questioning, nor an understanding of the level of expertise offered.
