Top RAG Developer Interview Questions

Questions to ask RAG Developers in technical interviews

How do you implement Retrieval-Augmented Generation in production?

Look for explanation of retrievers, vector databases, and prompt construction. Bonus if they’ve used LangChain or similar orchestration frameworks.

What embedding models have you worked with?

Expect OpenAI, SentenceTransformers, Cohere, or custom-trained models. Look for understanding of trade-offs in vector quality and size.

How do you manage document chunking and context windows?

They should discuss chunk size tuning, overlap strategies, and optimizing for retrieval quality.

What vector database platforms have you used?

Look for Pinecone, Weaviate, FAISS, or Qdrant. Bonus if they can discuss indexing, filtering, and scaling.

How do you evaluate the quality of RAG responses?

Expect mention of grounding checks, factual consistency, retrieval accuracy, and latency benchmarks.

How do you debug hallucinations in a RAG system?

Look for inspection of retrieval quality, prompt clarity, and source document alignment with generated output.

What’s your approach when retrieval returns irrelevant documents?

Expect query reformulation, vector database tuning, re-ranking strategies, and improved chunking techniques.

Describe how you monitor the relevance of RAG responses in production.

Expect mention of human feedback loops, embeddings drift detection, or semantic similarity scoring.

How do you troubleshoot latency in large-scale RAG pipelines?

Look for batched queries, optimized embeddings, and distributed retrieval systems.

What do you do when generation contradicts retrieved sources?

Expect use of grounding logic, answer masking, or formatting that highlights original source evidence.

Describe a time you collaborated across teams to ship a model to production.

Expect coordination with MLOps, product managers, and devs—plus ownership of handoff success.

Tell me about a time your deployment failed—what did you learn?

Look for ownership, alerting improvements, and resilience through iteration.

How do you handle tension between research and engineering constraints?

Expect pragmatism, backlog balancing, and milestone planning.

Describe how you respond when metrics stop improving.

Expect root cause analysis, feature engineering pivots, or label strategy reviews.

How do you manage technical debt in ML pipelines?

Look for scheduled cleanup, modular design, and team-wide knowledge sharing.

  • Misunderstands vector search performance trade-offs
  • Fails to optimize retrieval for domain-specific needs
  • Uses generic chunking/tokenization strategies blindly
  • Weak grasp of latency and scoring mechanisms
  • Overlooking fallback strategies for poor results
