YOUR BRIEF
What to work through
Work through rAG for company documents as a spoken system design interview. Start by clarifying the scope, sketch a working design and explain the trade-offs behind your choices.
- Ingest documents from the company’s tools and keep them current
- Answer a question in plain language, citing the passages used
- Use only content the asker is allowed to open
- Measure answer and retrieval quality over time
BEFORE YOU START
Constraints to discuss
- Millions of documents in the index
- Zero answers that cite a document the asker cannot open
- Chunks of 512 to 1,024 tokens
- Retrieval quality tracked with recall at K, MRR and NDCG
Need a starting point?
Watch for these common gaps as you prepare:
- Checking permissions after retrieval, or not at all
- No plan for updates and deletes, so answers cite old versions
- No evaluation set, so a change that hurts quality goes unseen
- Letting the model answer without passages, or without citations
