Inference / Serving Interview Support
Real-time proxy interview support for LLM serving and infra roles — vLLM/SGLang, Endpoints vs Providers, batching, KV cache, quantization, autoscaling, and serving system design.
Interviewing for an LLM serving or AI infrastructure role where system design will center on throughput, latency, and cost? These rounds reward real serving intuition. We support you live across the design and coding stages.
Serving/infra interviews are dominated by system design: how you would serve an open LLM at target QPS and latency, why continuous batching and PagedAttention matter, KV-cache and prefix caching, when to use vLLM vs SGLang vs managed Inference Endpoints (and how Inference Providers differ), quantization for memory, tensor parallelism for big models, autoscaling and cold starts, and cost per million tokens. We support you live, helping you reason about the trade-offs and defend an architecture — including noting that TGI is now legacy in favour of vLLM/SGLang. You attend and complete your own interview; support is real-time technical help only.
