1 hour: LeetCode medium problems, plus in-depth questions about computer hardware architecture and low-level C++ concepts, including: * Graphics pipelines * Stacks * Heaps * Threads * Mutexes * Atomics * Semaphores All that we love.

Was referred for this position. Went through 7 rounds of interviews. The questions were not very difficult data structure and algorithm questions. More focus was placed on approach and conceptual knowledge than on providing very difficult algorithm

Overall, the experience was not bad, and everyone was very nice. First was a take-home coding assignment. Unfortunately, I didn't pass the interview, and the process ended. This is a pretty standard process, similar to most tech companies.
