As a DevOps Engineer (GitOps & ArgoCD) at Workday, you should be proficient in Git, Kubernetes, ArgoCD, and Argo Workflows. Additionally, familiarity with CI/CD tools, containerization technologies like Docker, and monitoring/logging tools such as Prometheus or Grafana is advantageous. Staying informed about cloud platforms, particularly AWS and GCP, will also support your role effectively.

GitOps is a modern operational framework that uses Git as a single source of truth for both infrastructure and application configuration. In relation to DevOps, GitOps enhances collaboration and efficiency by automating deployment processes, enabling continuous delivery, and simplifying rollback procedures through version-controlled manifest files.

In preparing for this question, highlight your hands-on experience with ArgoCD, including how you've utilized it to manage Kubernetes declarations effectively. Discuss specific projects where you configured Argo Workflows to implement CI/CD pipelines, focusing on challenges you overcame and the outcomes of these implementations.

When asked about automation, it’s important to outline your step-by-step process starting from identifying repetitive tasks. Explain how you’ve used various tools, like ArgoCD and CI/CD pipelines, to automate deployment, testing, and monitoring, and emphasize any metrics or improvements resulting from these automations.

When addressing this question, share a specific incident where you encountered a deployment failure. Focus on your analysis of the problem, the remedial steps you took (such as debugging and collaboration), and the measures you put in place to prevent future occurrences. Highlight any resulting improvements in deployment processes.

Talk about the various security methodologies you implement during deployments. This might include access controls, regular audits, integration of security tools into your CI/CD pipelines, and following best practices for container security, such as image scanning and vulnerability assessments.

Share your preferred CI/CD tools based on your experience, such as Jenkins, GitLab CI, or CircleCI. Explain your reasoning, showcasing your hands-on knowledge of their features, flexibility, and how they integrate with other tools you use, like ArgoCD for GitOps practices.

Key concepts of Kubernetes include Pods, Services, Deployments, ConfigMaps, and Persistent Volumes. Make sure to not only define these terms but also discuss how you’ve applied them in real-world scenarios, such as scaling applications, managing configurations, and ensuring service discovery.

Discuss your experience using monitoring tools such as Grafana, Prometheus, or ELK stack. Explain how you’ve set alerts, collected metrics, and utilized logs to gain insights into application performance. Emphasize proactive measures you’ve taken to enhance system observability and performance management.

Collaboration is fundamental in DevOps. You might want to talk about your experiences working with cross-functional teams, sharing knowledge with developers, and maintaining open lines of communication to assure that everyone is aligned on deployment strategies and operations.

In your response, share your insights into the evolution of DevOps towards GitOps, emphasizing the benefits of a Git-driven infrastructure management approach. Discuss how GitOps can simplify processes, enable better collaboration, and enhance deployment reliability in fast-paced development environments.
