Likely interview questions for this role
Written from this job description, not a generic list. Each one notes what the interviewer is really checking.
About your past
Tell me about something you automated that removed toil for your team.
What they are checking: Whether they treat repeated manual work as a problem to eliminate, which is the core of reliability work.
Walk me through an incident you handled from alert to postmortem.
What they are checking: Whether they communicate during incidents and turn the postmortem into real fixes without blame.
What would you do
How would you run a Kubernetes cluster upgrade across on-prem and cloud clusters with minimal disruption?
What they are checking: Planning around version skew, workload disruption budgets and rollback across different environments.
A desk asks for a special cluster setup just for them. How do you respond?
What they are checking: Balancing helpfulness against keeping the platform simple and standard, which the team says it values.
About the work
The Container Infrastructure team runs orchestration on-premises and in the cloud. Walk me through how you have operated Kubernetes in production.
What they are checking: Real hands-on experience with clusters, upgrades and failures rather than only deploying apps onto someone else's cluster.
A pod keeps restarting in a production namespace used by a trading desk. How do you work out why?
What they are checking: A methodical path through events, logs, probes, resource limits and node health instead of guessing.
How do you define what reliable means for a platform that serves trading desks, data scientists and enterprise apps?
What they are checking: Whether they can set service-level objectives that reflect what each type of user actually needs.
How do you approach networking and ingress for containers that need to talk to on-prem trading systems?
What they are checking: Understanding of CNI, service exposure and the latency and security concerns of hybrid connectivity.
How do you manage cluster configuration and deployments so they are repeatable?
What they are checking: Use of infrastructure as code, GitOps and Helm or similar so clusters do not drift.
How do you keep secrets and access to clusters secure while still letting many teams deploy?
What they are checking: Knowledge of RBAC, namespaces and secret management that balances safety with self-service.
