1. What is a DevOps Engineer at Aubay Spain?
As a DevOps Engineer at Aubay Spain, you are not just building infrastructure; you are acting as a strategic technical consultant for some of the largest enterprises in Europe. Aubay is a leading digital services company, and our DevOps engineers are embedded within critical client projects to bridge the gap between software development and IT operations. Your work directly impacts the speed, security, and reliability of product delivery for major brands across telecommunications, banking, and energy sectors.
In this role, you will design, implement, and maintain robust CI/CD pipelines, manage scalable cloud infrastructures, and automate operational workflows. Because Aubay operates on a consultancy model, you will frequently collaborate with both internal Aubay experts and external client stakeholders. This requires a unique blend of deep technical expertise and strong client-facing communication skills.
What makes this position truly compelling is the variety and scale of the challenges you will face. You might be modernizing legacy systems for a financial institution one year, and architecting a cutting-edge, cloud-native microservices platform for a retail giant the next. You are the catalyst for engineering efficiency, ensuring that high-quality code reaches production environments seamlessly and securely.

To succeed in the Aubay Spain interview process, you must approach your preparation with a dual focus: technical mastery and consulting readiness. You will be evaluated not only on your ability to configure tools, but on how effectively you can integrate into a client's existing engineering culture.
Technical Proficiency – Interviewers will assess your hands-on experience with modern DevOps tools and cloud platforms. You can demonstrate strength here by clearly explaining how you have used tools like Terraform, AWS, and Azure to solve real-world infrastructure problems, rather than just listing technologies.
Problem-Solving & Automation – At Aubay, we value engineers who proactively identify bottlenecks. You will be evaluated on your ability to design automated CI/CD pipelines and troubleshoot deployment failures. You should be prepared to walk through your logical process for diagnosing production issues and implementing scalable fixes.
Consulting & Communication Skills – Because you will often interview with and work directly for our clients, your ability to articulate complex technical concepts in clear, professional English is critical. Showcasing a collaborative, adaptable mindset will strongly differentiate you from other candidates.
Cultural Fit & Adaptability – Aubay engineers must be highly adaptable, quickly learning new client environments and tech stacks. Interviewers look for candidates who demonstrate resilience, eagerness to learn, and a track record of successfully navigating shifting project requirements.
4. Interview Process Overview
The interview process for a DevOps Engineer at Aubay Spain is highly structured, typically consisting of three to four main stages. Because we are a consultancy, the process is uniquely split between internal Aubay evaluations and a final technical validation with the specific client you will be assigned to. The overall difficulty is generally considered manageable, provided you have a solid grasp of your core technical fundamentals and can confidently discuss the experiences listed on your resume.
Your journey will begin with a recruiter screen that includes a behavioral assessment and an English proficiency evaluation. If successful, you will move on to an online technical assessment, frequently hosted on platforms like CodinGame, which consists of multiple-choice questions testing your foundational DevOps and programming knowledge. Passing this grants you an interview with an internal Aubay technical specialist who will dive deep into your resume, asking specific questions about your preferred tools, cloud platforms, and deployment strategies.
The final stage is a technical and cultural interview with the contracting client's engineering team or manager. This step ensures that your technical background aligns perfectly with the client's current tech stack and project needs. Once all stages are cleared, the process moves swiftly into the offer stage, which often includes comprehensive support from our legal department for visa processing and relocation logistics if you are moving from abroad.
This visual timeline outlines the typical progression from your initial recruiter screen through the technical assessments and final client interview. Use this to pace your preparation; focus heavily on fundamental concepts for the initial online test, and shift toward deep, narrative-driven explanations of your past projects for the Aubay specialist and client rounds. Note that the final client round may vary slightly in focus depending on the specific project you are being considered for.
5. Deep Dive into Evaluation Areas
To excel in your interviews, you must be prepared to discuss both the high-level architecture and the low-level implementation details of your past work. The technical evaluations will heavily focus on the technologies clearly stated on your resume, so expect deep-dive questions on your specific areas of expertise.
Cloud Infrastructure and Cloud Providers
Understanding cloud ecosystems is non-negotiable for this role. You will be evaluated on your ability to architect, provision, and manage resources in public clouds. Strong performance means demonstrating a clear understanding of cloud-native networking, security, and compute services.
Be ready to go over:
- AWS and Azure Fundamentals – Core services like EC2, S3, RDS, VPCs in AWS, or their Azure equivalents. You must know how to secure and scale these resources.
- High Availability and Disaster Recovery – Designing multi-region or multi-AZ architectures to ensure maximum uptime for client applications.
- Cost Optimization – Strategies for monitoring and reducing cloud spend, which is a frequent concern for enterprise clients.
- Advanced concepts (less common) – Hybrid cloud connectivity, advanced IAM policy scripting, and serverless architectures.
Example questions or scenarios:
- "Can you explain the difference between a public and private subnet in AWS, and how you would route traffic between them securely?"
- "Walk me through how you would design a highly available web application architecture on Azure."
- "How do you handle secrets management and secure access to cloud resources in a production environment?"
Infrastructure as Code (IaC)
Aubay Spain relies heavily on automation to deploy infrastructure reliably and consistently across different client environments. Your proficiency with IaC tools is a major evaluation point. Interviewers want to see that you treat infrastructure with the same rigor as application code.
Be ready to go over:
- Terraform Proficiency – Writing modular, reusable Terraform code. Understanding state management and remote backends.
- Configuration Management – Using tools like Ansible, Chef, or Puppet to configure servers post-provisioning.
- Version Control for Infrastructure – Managing infrastructure changes through Git, using pull requests and peer reviews.
- Advanced concepts (less common) – Writing custom Terraform providers, testing IaC using tools like Terratest, and managing drift in long-running environments.
Example questions or scenarios:
- "How do you manage Terraform state files securely in a collaborative team environment?"
- "Explain the concept of infrastructure drift and how you detect and resolve it."
- "If you need to deploy identical infrastructure across multiple environments (Dev, QA, Prod), how do you structure your Terraform modules?"
CI/CD and Deployment Strategies
A core responsibility of this role is ensuring that code moves from a developer's machine to the production environment safely and efficiently. You will be tested on your ability to build, optimize, and troubleshoot deployment pipelines.
Be ready to go over:
- Pipeline Architecture – Designing multi-stage CI/CD pipelines using tools like Jenkins, GitLab CI, or GitHub Actions.
- Deployment Methodologies – Understanding the differences between Blue/Green, Canary, and Rolling deployments, and knowing when to use each.
- Containerization and Orchestration – Building Docker images efficiently and deploying them to container orchestrators like Kubernetes.
- Advanced concepts (less common) – Implementing GitOps workflows with tools like ArgoCD, or setting up automated rollback mechanisms.
Example questions or scenarios:
- "Walk me through the exact steps required to deploy a containerized application to a production environment."
- "A deployment pipeline fails consistently at the integration testing stage. How do you troubleshoot and resolve the issue?"
- "Explain how you would implement a zero-downtime deployment for a critical client-facing application."
