Roles that use Kubernetes
See how hiring teams interview engineers on Kubernetes, in production-like environments.
Platform Engineer
Hire platform engineers who reduce friction for every team. Real golden-path templates, real internal CLIs, real service onboarding flows. We record every step.
See the interviewDevOps Engineer
Hire DevOps engineers who actually ship. Run live or take-home interviews in production-like Linux environments with Docker, Kubernetes, Terraform and CI/CD. See how they debug, automate, and work alongside AI.
See the interviewSite Reliability Engineer (SRE)
Hire SREs who actually run production. Live workspaces with metrics, logs, traces and a service that is starting to misbehave. We record every keystroke.
