There were three interviews on the same day, each lasting about 50 minutes with a 10-minute break in between. The interviews can usually be code interviews, system design interviews, or, if you are lucky, behavioral interviews.

Slow or minimal feedback after the interview. You have to push for feedback or wait. In my case, I waited for two weeks, then pushed the recruiter for feedback.

The process was a recruiter call and a technical phone screen focused on deep GPU fundamentals, including the GPU lifecycle, architecture, contention, and performance. I was also asked to explain Radix Sort and GPU behavior details.
