NVIDIA Software Developer interview questions

I spoke to the Hiring Manger - who was great and kind. I found the Recruiter to not be so responsive and not give so much information regarding what's to come. I had a technical interview with 2 engineers remotely where I had one riddle and one bit manipulation question. Overall I didn't find it to be too hard - more just out of no where and a very low level for a position that is not embedded
