Tl;dr: Long interview process, very intellectually stimulating conversations, no offer in the end because of internal restructuring. The interviewers were real experts in the different skill areas needed for the job, and they asked abstract, open-ended questions. Each interviewer felt highly qualified. Each interview ended up being an interesting discussion. In the end, the recruiter told me that because of some internal restructuring, the role had to be cancelled.

Recruiter gave all needed info about the recruitment process. I had 5 interviews with different interviewers. Each interview was to check my knowledge in different areas. First interview was with the hiring manager to verify if I fit to the team. Next interviews were about: problem solving, parallel programming, CPU/GPU architecture, C++ profiling and optimisation, AI/LLM. All interviews were in a nice atmosphere. Many questions required solving simple tasks using knowledge from the given field. The interview about C++ profiling and optimisation was actually about CPU/GPU architecture not about C++. Mostly it was touching the same topics as the CPU/GPU architecture interview.
Confirmed questions1 question
- Difference between CPU architecture and GPU architecture. Task for logical thinking connected to sorting algorithms.

I had a phone interview that was set up through a recruiter on LinkedIn. I first talked on the phone with a member from the Tegra mobile platform team and even though he was mainly looking for people with experience in performance tuning (which I did not have), he liked my resume and passed it along to another team member. Then I had another interview and this interviewer was very nice and friendly. He spent about 15 minutes giving me a brief description of his work at Nvidia. Then he went through my resume and asked a couple of questions about a graphics project I had built. After that, he asked me 2 problems and my interview was over.
Confirmed questions2 questions
- Given two numbers a and b, we use an averaging function (a+b)/2. This function fails in some specific cases. I had to say what that case is, and also how to fix or handle it.
- Given an unsigned char c, swap each pair of bits in it (swap every two bits).
