The process took 4 weeks. I interviewed at NVIDIA in Apr 2012
Interview
Two phone interview, one onsite, and one coding problem afterwards. The whole process takes about a month, and it went pretty well. Meet a lot of good engineers and have good discussion about technique details, resume, coding problem, etc. It not very hard, but requires a lot of preparation and lucky, I am glad I got the offer at the end, although I did not accept it.
Interview questions [1]
Question 1
I'd better not say too much about it, but some questions like the details of the project you did, and how could you extend it to make it better, or what's your understanding of some implementation or optimization.
A non technical phone interview with hiring manager
One onsite technical interview with hiring manager which included 2 technical questions.
One online technical interview took 2 hours with hiring team lead which included 3 technical questions

Question 1
One logical question and one leetcode style quesiton
Had a technical interview of 2 hours where they told me a little bit about the job, asked me to introduce myself, asked me about a project I did, and then there was a coding question.

Question 1
Asked me to explain about a project I did in university.
A typical software engineering coding interview focuses on problem-solving under time pressure. Candidates are usually given one or more algorithmic problems similar to those found on LeetCode. The interviewer evaluates data structures, algorithm selection, code correctness, time and space complexity analysis, communication clarity, edge-case handling, and debugging ability. Interviews often begin with clarifying questions, followed by writing executable or near-executable code on a shared editor or whiteboard. Strong candidates explain trade-offs, optimize incrementally, test thoughtfully, and remain calm while reasoning through unfamiliar problems.
