Your question is Explain Your Take-Home Architecture. Take a moment with it on the right.
Talk me through your thinking if you like. When you're confident, submit your answer and I'll grade it like a real screen (7/10 or better passes).
Present your take-home agent: why this architecture, why this approach to tool calling?
Asked in the onsite presentation stage. Explain the system you built, the major architectural decisions, and how the agent selects, invokes, and handles tools. Be prepared to discuss alternatives, limitations, reliability, and how you would improve the design.
