Agent Engineer Interview Prep

Question categories:

1. Fundamentals — Tool use vs function calling? ReAct vs Plan-and-Execute?
2. System design — "Design a research agent for 100K users" (10K msg/hour, $5 budget/user/month)
3. Trade-off — "When is multi-agent overkill?"
4. Safety — "How would you indirect-inject this agent? How would you defend?"
5. Eval — "How would you measure this agent's success?"
6. Production — "The agent crashed — debug?"
7. Code — "Write this simple agent" (live codecoding)

Prep: implement 5 agent examples from Anthropic Cookbook + present your portfolio projects.
