AI agent tool calling interview questions

Show how you classify failures, control side effects, and recover safely.

Classify failures first

Invalid parameters, permissions, timeouts, rate limits, and parsing errors require different responses. Do not retry every failure indiscriminately.

Design idempotency and recovery

Use stable identifiers for writes. When a result is unknown, read actual state before retrying. Track completed steps to avoid repeated side effects.

Prepare for a live change

Consider reduced budget, human handoff, or repeated execution. Explain how you would change, verify, and document the workflow.
