Summary
SRE vs platform engineer vs DevOps—pick the label the job uses.
Experience bullets
Security scanning tools need policy outcomes, not just installation.
Common mistakes
- Kubernetes words without cluster ownership experience.
- GitOps tools without sync/rollback story.
- Observability stack listed without SLO/on-call usage.
- Security scanners without enforcement or policy outcomes.
