A friendly first-round call: fundamentals of pipelines, containers and Linux, plus how you learn on the job.
1. Walk me through what happens, step by step, between a developer merging to main and that change serving production traffic in your most recent setup.
~3 minChecks whether the candidate owns the full delivery path rather than a single tool.
2. A deployment goes out at 16:40 and error rates on one service triple within four minutes. Talk me through your first fifteen minutes.
~3 minAssesses incident instinct: stabilise first, diagnose second.
3. How do you structure Terraform across multiple environments and teams so state stays safe and changes stay reviewable?
~3 minLooks for real infrastructure-as-code experience beyond a single root module.
4. Your Kubernetes cluster costs 40% more than budget but latency SLOs are comfortably met. What do you investigate and what trade-offs do you present?
~3 minTests cost-versus-reliability judgement and stakeholder framing.
