To succeed, you must demonstrate proficiency in specific technical domains relevant to the Federal Intelligence space.
Infrastructure as Code (IaC) & Cloud Platforms
You must be comfortable defining infrastructure programmatically. AnaVation relies heavily on Terraform and Ansible to manage environments across AWS (specifically GovCloud, C2S, and SC2S) and on-premise virtualization like VMware vSphere.
Be ready to go over:
- Terraform State Management: Handling state locking, remote state storage, and module design for reusability.
- Configuration Management: Using Ansible playbooks to patch servers, manage users, and ensure configuration consistency across hundreds of nodes.
- AWS GovCloud/C2S nuances: Understanding the differences between commercial AWS and the isolated regions used by the government.
- Advanced concepts: Writing custom Terraform providers or using Ansible Tower/AWX for orchestration.
Example questions or scenarios:
- "How would you structure a Terraform project to manage infrastructure across multiple isolated enclaves (Unclassified vs. Secret)?"
- "Describe a situation where an Ansible playbook failed halfway through. How did you recover the system to a known good state?"
CI/CD & DevSecOps
The core of your role involves building secure pipelines. You need to show expertise in GitLab CI, integrating security tools, and managing artifact repositories like JFrog Artifactory or Sonatype Nexus.
Be ready to go over:
- Pipeline Architecture: Designing multi-stage pipelines (Build, Test, Scan, Deploy) that support Agile Release Trains.
- Security Integration: Implementing SAST/DAST scanning, container image scanning, and SBOM generation within the pipeline.
- Version Control: Advanced Git workflows, branching strategies, and resolving merge conflicts.
Example questions or scenarios:
- "We need to ensure no container is deployed without passing a vulnerability scan. Walk me through how you would enforce this in a GitLab pipeline."
- "How do you handle secrets management (e.g., API keys, certificates) in a CI/CD pipeline without exposing them in the code?"
Linux Administration & Troubleshooting
Because you will be supporting "dynamic web applications" and "cluster-based computing," deep Linux knowledge (RedHat, Rocky, Ubuntu) is non-negotiable. You are the O&M owner, meaning you fix what breaks.
Be ready to go over:
- System Hardening: Applying STIGs, managing SELinux policies, and configuring firewalls (iptables/firewalld).
- Performance Tuning: Debugging high load, memory leaks, or I/O bottlenecks using tools like
top, strace, or tcpdump.
- Scripting: Writing robust Bash or Python scripts to automate routine patching or log rotation.
Example questions or scenarios:
- "A production Linux server is unresponsive. Walk me through your troubleshooting steps from the moment you log in."
- "How do you automate the patching of 500 servers while ensuring zero downtime for the application?"
Containerization & Orchestration
Modernizing legacy applications is a key part of the mission. You need fluency in Docker and Kubernetes to deploy and manage microservices.
Be ready to go over:
- Kubernetes Primitives: Pods, Deployments, Services, Ingress, and ConfigMaps.
- Cluster Maintenance: Upgrading K8s versions, managing etcd backups, and debugging crash loops.
- Observability: Configuring Prometheus and Grafana to monitor cluster health.
Example questions or scenarios:
- "A pod in your Kubernetes cluster keeps restarting with an OOMKilled error. How do you diagnose and fix this?"
- "Explain the difference between a StatefulSet and a Deployment. When would you use one over the other?"
