NVIDIA Software Developer interview questions

I first got 2 telephone interviews, which were not that difficult and mostly based on Computer Networks and OS. Then I was called onsite. I had 6 Interviews - 2 telephony, 1 lunch, 3 face to face. The onsite telephone interviews weren't clear and though the job description didn't mention Machine Learning and Compiler Construction I was asked questions about it.

There was a written test which consisted of quantitative aptitude, logical reasoning, OS and Programming. After that there were 2 Tech rounds followed by managerial and HR Rounds. Using quant and LR for judging people with 3 years experience isn't that fair. People who have done training for CAT or GMAT have a clear advantage.
