I had a phone interview arranged through a recruiter on LinkedIn.

I had a phone interview with a member from the Tegra Mobile Platform team. Though he was looking for people with experience in performance tuning (which I did not have), he liked my resume and forwarded it to another team member.

Then I had another interview, and the interviewer was very nice and friendly. He gave me a brief description of his work at Nvidia for about 15 minutes. He then moved on to my resume and asked a couple of questions regarding a graphics project that I had built. Finally, he asked me two problems, and my interview was over.

Given two numbers, a and b, we have an averaging function (a+b)/2. This function won't work under certain cases.

I was supposed to tell the case and also how to handle it.

Given an unsigned char c, swap every two bits of it.
