How do you handle an LLM agents interview?
Company: Anthropic
Role: Software Engineer
Category: ML System Design
Difficulty: hard
Interview Round: Onsite
You have an interview on your agenda titled **“Agents Interview.”**
Explain how you would approach this interview if it is about designing and evaluating an **LLM-powered agent** (a system that can plan, use tools/APIs, and complete multi-step tasks).
Cover:
- What clarifying questions you would ask about the agent’s **use case** and constraints.
- A high-level **architecture** (LLM, tools, orchestration, memory/state, retrieval, guardrails).
- How you would ensure **reliability** (tool failures, retries, idempotency, timeouts), **safety** (prompt injection/data exfiltration), and **cost/latency** control.
- How you would **evaluate** and iterate (offline eval, online metrics, human-in-the-loop, regression testing).
Quick Answer: This question evaluates an engineer's competency in designing and evaluating LLM-powered agents, covering system architecture, tool and API integration, planning and state management, reliability and safety mitigations, and evaluation methodologies.
