  1. Walk me through how you'd design an agentic workflow that integrates AI-powered capabilities into an existing engineering operations process. What does the agent own versus what stays human-in-the-loop, and how do you guard against the agent taking a wrong automated action in production?
    From the posting: “Design and implement agent-driven workflows and intelligent automation solutions. Integrate AI powered capabilities into engineering and operational processes. Establish best practices for responsible AI adoption within software delivery lifecycles.”
  2. It's peak transaction time and your CI/CD pipeline just deployed a change to the payment switching service. Latency on the switching path has spiked and some transactions are timing out. Walk me through how you troubleshoot this live.
