How to Prepare for This Role

1. This role sits at the intersection of Kubernetes operations, CI/CD automation, and Linux system administration. With 3-4 years of experience required, the focus is on practical hands-on ability. Structure your CV around specific Kubernetes environments you managed, pipelines you built, and production incidents you resolved rather than listing tools in isolation.
2. Kubernetes is the primary platform focus. Be ready to explain multi-node cluster management, control-plane components including ETCD and API Server configuration, and container networking concepts. Interviewers will probe your understanding of high-availability workload design, not just basic deployment steps.
3. CI/CD pipeline experience with Jenkins and Argo CD is explicitly required. Prepare to walk through a pipeline you designed or maintained end to end, including how you managed Jenkinsfiles, configured Argo CD application deployments, and handled rollback scenarios in a production environment.
4. Linux system administration is a core part of this role covering security hardening, ACL-based file system security, firewall controls with FirewallD, IPTables, and UFW, and infrastructure services including NFS, FTP, HTTPD, NTP, and HAProxy. Review these areas systematically and be ready to demonstrate command-line proficiency during technical rounds.
5. Observability and monitoring using Prometheus, Grafana, Jaeger, Zipkin, and Elastic Observability are listed as responsibilities. Prepare to explain how you have set up monitoring stacks, configured dashboards, and used distributed tracing to diagnose microservices issues in production. Open Telemetry knowledge is also specifically called out.
6. Linux Administration certification is listed as preferred. If you hold RHCSA, LPIC, or equivalent, place it prominently on your CV. If not, be ready to demonstrate equivalent practical depth through the real-world tools, configurations, and on-call incident scenarios you have experienced.
