- 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?
- 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.
- Tell me about a time you had to modernize or refactor a critical piece of infrastructure or codebase. What was your approach, and how did you manage the risk?
