Knowing the algorithms is only half the job. The rest is the serving stack that actually delivers throughput within a latency budget. What they grade is whether you match the server to the workload and name the four knobs that move the needle.

Almost nobody builds a serving stack by hand. What interviewers watch for is whether you know what frameworks give you (batching, multi-model, GPU scheduling) and why LLM-specific servers even exist when general ones batch already.
