Senior System Software Engineer Interview Questions

9 senior system software engineer interview questions shared by candidates

He asked very specific troubleshooting questions of a multi-GPU multi-node cluster configuration, which may have performance issues, i.e. surprisingly low effective bandwidth in device-to-device communication, even on the same host. Question was what was the most likely culprit. The degree of troubleshooting for an NVIDIA-specific setting was quite high.

typical ice breakers like volatile, static etc. question about compiler optimization. what happens if compiler can't store variable in a register ? then gave me a code snippet to find bug. was an array out of bounds access in a for loop. then in last 10 mins or so, asked me to write malloc and free for a fixed buffer array and return offset to user.
