Most developers think RAG is simple — store embeddings in a vector database and call the LLM. But that is naive RAG, and it will never survive in production. In this video, we break down how to design a truly production-ready RAG system in a structured interview Q&A format, covering everything an AI Engineer or LLM Engineer is expected to know in system design interviews.
We walk through the five critical components of production RAG — hybrid search, metadata filtering, re-ranking, guardrails and validation, and caching strategy. We then compare naive RAG versus production RAG architecture step by step, and close with a three-test framework — Accuracy, Latency, and Cost — that helps you determine whether your RAG system is actually ready for production. A senior-level insight is included that demonstrates architectural maturity to interviewers.
