• Advanced concepts (less common) – Multi-region active-active architectures, hybrid-cloud connectivity using Direct Connect or ExpressRoute, and advanced cost-optimization strategies.

Example questions or scenarios:

• "How would you design a secure, multi-region database replication strategy across both AWS and Azure?"
• "Walk me through how you would refactor a monolithic infrastructure template into reusable, version-controlled Terraform modules."

CI/CD Pipeline Engineering & Automation

This area tests your ability to build efficient, secure, and reliable automated pipelines that enable continuous integration and continuous delivery.

Be ready to go over:

• Pipeline Design & Tools – Building pipelines using tools like Jenkins, GitLab CI, GitHub Actions, or Azure DevOps.
• Artifact & Dependency Management – Managing container registries, artifact repositories, and versioning strategies.
• Testing & Security Integration – Automating unit tests, integration tests, vulnerability scanning, and compliance checks within the pipeline.
• Advanced concepts (less common) – GitOps workflows with ArgoCD or Flux, canary and blue-green deployment patterns, and automated rollback strategies using monitoring metrics.

Example questions or scenarios:

• "Describe how you would configure a pipeline to deploy a microservice to a Kubernetes cluster using a blue-green deployment strategy."
• "How do you handle a scenario where a third-party dependency scan fails in the middle of a production release pipeline?"

Whiteboard System Design & Presentation

This round assesses your ability to architect complex systems on the fly and communicate your design decisions clearly to a technical audience.

Be ready to go over:

• System Architecture Design – Designing scalable, fault-tolerant, and secure system architectures based on a set of requirements.
• Visual Communication – Drawing clear, logical architecture diagrams on a whiteboard and explaining the data flow.
• Trade-off Analysis – Explaining the pros and cons of your design decisions, such as choosing SQL vs. NoSQL, or synchronous vs. asynchronous communication.
• Advanced concepts (less common) – Designing for extreme scale, implementing zero-trust security architectures, and architecting complex event-driven systems.

Example questions or scenarios:

• "Use the whiteboard to design a highly available logging infrastructure that can ingest and analyze terabytes of log data per day from multiple cloud regions."
• "Draw and explain the architecture for a real-time data processing pipeline that feeds a dashboard with minimal latency."

As a DevOps Engineer at Ntt Data Europe & Latam, your daily work will be dynamic, collaborative, and highly impactful. You will be responsible for bridging the gap between development and operations to deliver high-quality software solutions.

You will spend a significant portion of your time designing and implementing automated pipelines that build, test, and deploy software. This involves collaborating closely with software engineering teams to understand their application architectures, helping them containerize their workloads, and ensuring their code can be deployed reliably and securely. You will write code to automate everything—from infrastructure provisioning using Terraform to configuration management and system monitoring.

Additionally, you will play a key role in cloud migration and modernization initiatives. This includes helping clients transition from legacy on-premises systems to modern, cloud-native architectures.
