Debug INT4 regression in a multi-tenant AI support platform
Mid-Level debugging interview question on INT4 within LLM Inference & Optimization.
Quick answer
Start by framing the problem in production terms for INT4, then explain the root causes, a step-by-step investigation path, and the architecture or process changes you would ship for a Mid-Level LLM Inference & Optimization role.
The interview question
After a recent release, a multi-tenant AI support platform shows latency spikes while quality remains flat. Logs suggest the problem may involve INT4, but multiple subsystems changed in the same deploy. Walk through how you would isolate the root cause.
