• Cloud Architecture – Understanding the nuances of public vs. private cloud and how to design for high availability.
• Containerization – Mastery of Docker and Kubernetes, specifically how to manage clusters and optimize resource allocation.
• Advanced concepts – Multi-cloud strategy, service mesh (Istio), and software-defined networking (SDN).

Example questions or scenarios:

• "How would you design a highly available architecture for a global application across multiple regions?"
• "Describe a situation where you had to migrate a legacy service to a containerized environment."
• "What are the primary challenges of managing state in a Terraform-managed environment?"

Automation and CI/CD Pipelines

At Orange, DevOps is synonymous with automation. You will be evaluated on your ability to build robust, secure, and efficient pipelines that empower developers to ship code frequently and safely.

Be ready to go over:

• Pipeline Design – Experience with Jenkins, GitLab CI, or GitHub Actions.
• Security Integration – How to incorporate automated security scanning (DevSecOps) into the build process.
• Release Strategies – Understanding Blue/Green deployments, Canary releases, and rollback mechanisms.

Example questions or scenarios:

• "How do you ensure that a CI/CD pipeline remains secure while maintaining high developer velocity?"
• "Walk me through the steps you take to automate a manual deployment process."

System Administration and Scripting

A strong DevOps Engineer must be a power user of the underlying systems. Orange relies heavily on Linux environments, and your ability to navigate the command line and automate tasks via scripting is essential.

Be ready to go over:

• Linux Internals – Knowledge of process management, file systems, and performance tuning.
• Scripting – Proficiency in Python or Bash for automating routine operational tasks.
• Troubleshooting – Ability to diagnose system-level bottlenecks and network latency issues.

Example questions or scenarios:

• "Explain the difference between a process and a thread in a Linux environment."
• "How would you debug a performance issue in a production environment where the CPU usage is spiking?"

As a DevOps Engineer at Orange, your daily activities will revolve around the continuous improvement of the platform and the developer experience. You will be responsible for designing and implementing the automation that drives the software development lifecycle. This involves working closely with software engineers to understand their requirements and providing them with the tools and infrastructure they need to succeed.
