Design a Retrieval-Augmented Generation pipeline that provides accurate, up-to-date financial and tax knowledge to power Intuit's AI features across TurboTax and QuickBooks.
Core to Intuit's GenOS platform and Intuit Assist. Tests deep understanding of RAG architecture, embedding strategies, and the unique challenges of financial knowledge retrieval.
What the Interviewer Expects
- Design an end-to-end RAG pipeline with document ingestion, chunking, embedding, retrieval, and generation
- Handle knowledge updates when tax laws change annually without full re-indexing
- Implement hybrid search combining semantic and keyword retrieval for financial terms
- Design evaluation metrics specific to financial accuracy and citation correctness
- Address latency requirements for real-time conversational use
Key Topics to Cover
How to Approach This
- Start by clarifying functional and non-functional requirements with the interviewer.
- Estimate the scale: QPS, storage, bandwidth. This drives your design decisions.
- Draw a high-level architecture first, then deep dive into 1-2 critical components.
- Discuss trade-offs explicitly (e.g., consistency vs availability, SQL vs NoSQL).
- Address failure scenarios, monitoring, and how the system handles 10x traffic spikes.
Possible Follow-up Questions
- How do you handle conflicting information between federal and state tax rules?
- What chunking strategy works best for IRS publications with complex cross-references?
- How do you evaluate whether the RAG pipeline is improving over time?
- How would you handle a query that requires reasoning across multiple retrieved documents?

Document Ingestion and Chunking
Ingest documents from IRS publications, state tax codes, Intuit help articles, and CPA-reviewed Q&A pairs. Use hierarchical chunking that preserves do...
Embedding and Retrieval
Use a hybrid retrieval strategy combining dense embeddings (financial domain-tuned model) with sparse BM25 search. Financial queries often contain spe...
