How to explain a RAG project in an interview

Organize a clear project discussion around goals, design, verification, failures, and tradeoffs.

Explain goals and your contribution

Describe the user problem and the specific parts you completed. Then outline the flow from documents to retrieval, answers, and sources.

Make quality claims concrete

Bring a question set, actual results, and a failure case. Distinguish missing retrieval evidence from a model failing to use evidence correctly, and explain how you verified each.

Respond to changed conditions

For permission, budget, or data-update requirements, identify the impact before proposing changes and regression tests. Acknowledge what remains unverified.
