How do you reduce hallucinations in RAG systems? (ANSWERED)
Hallucination in RAG systems is the #1 production failure mode cited in AI engineering interviews. Your interviewer wants a systematic debugging framework — not a list of buzzwords. Learn how to measure faithfulness, fix retrieval precision, and layer mitigations the way senior engineers at Databricks and Meta actually ship RAG.

TL;DR — Quick Answer
Improve retrieval precision with hybrid search and re-ranking, add citation requirements, implement faithfulness checks, and tune chunk overlap and metadata filtering.
