Debugging and Diagnostics Questions

Systematic approaches to diagnosing and fixing game bugs and performance issues. Topics include instrumentation and logging strategies, deterministic replay and reproducibility, crash reporting and postmortems, memory and leak detection, race condition and concurrency debugging, graphics and shader debugging, network trace analysis for multiplayer issues, remote diagnostics, and use of profilers and debugging tools. Interview questions typically ask candidates to outline steps to reproduce a bug, to propose diagnostic pipelines, or to explain how they would triage and resolve a hard to reproduce multiplayer or performance problem.
