Welcoming questions

  1. Can you tell us about yourself and the platforms you have run?
  2. What does a good deployment process look like to you?

Role-specific / technical competencies

  1. Walk us through a CI/CD pipeline you built. What made it fast and safe?
  2. How do you structure Terraform or other IaC for multiple environments?
  3. Describe your approach to monitoring: what do you alert on and what do you deliberately not?
  4. How do you manage secrets across environments and pipelines?
  5. Tell us about a cloud cost problem you found and fixed.

Behavioural & culture fit

  1. Describe the worst outage you have handled. What was your role, and what changed afterwards?
  2. How do you spread operational ownership to developers instead of becoming the bottleneck?
  3. Tell us about a time you automated away a task everyone had accepted as manual.

Problem-solving / case

  1. Deployments started failing intermittently this morning with no code changes. How do you investigate?
  2. The API's p99 latency doubled after a release that passed all checks. Walk us through your response.
  3. Leadership wants deployment frequency to go from weekly to daily without more incidents. What is your plan?
