Description: When a RAG system produces incorrect answers, the problem often starts long before the LLM response. Data engineers must trace failures across ingestion, chunking, embeddings, retrieval, reranking, context limits, and prompt design to identify where accuracy breaks down and how to fix it efficiently.
