Design an AI assistant like Intuit Assist that helps small business owners with bookkeeping questions, tax advice, and financial insights using natural language.
A newer question type reflecting Intuit's AI-first strategy. Tests understanding of RAG architectures, LLM integration, and the unique challenges of AI in financial contexts.
What the Interviewer Expects
- Design a RAG architecture that grounds LLM responses in accurate financial data and tax rules
- Implement guardrails to prevent incorrect financial advice that could have legal consequences
- Handle multi-turn conversations with context about the user's specific financial situation
- Design confidence scoring and escalation paths to human experts when AI is uncertain
- Address latency requirements for real-time conversational experience
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 prevent the AI from giving incorrect tax advice that could result in IRS penalties?
- How would you evaluate the accuracy of the assistant's financial recommendations?
- What is your strategy for keeping the AI current with annually changing tax laws?
- How do you handle personally identifiable financial information in the LLM pipeline?
