Interview questions [1]
Question 1
I had prior experience with similar roles, so some of the questions involved proprietary knowledge; for example one interviewer showed me output from their internal GPU performance analyzer and asked me to describe what was happening at the hardware level. I was also asked to expand on prior projects at previous companies, and to discuss trending technologies and how I expected them to impact future products.
