Aubay Spain DevOps Engineer interview questions & guide 2026

The questions below represent the patterns and themes frequently encountered by candidates interviewing for DevOps roles at Aubay Spain. While you should not memorize answers, you should use these to practice structuring your responses around your real-world experience.

Cloud and Infrastructure as Code

Interviewers want to verify that you can provision and manage cloud resources securely and efficiently using code.

• How do you structure your Terraform projects for scalability and reusability?
• What is the difference between an Application Load Balancer and a Network Load Balancer in AWS?

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.

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.

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.

As a DevOps Engineer at Aubay Spain, your day-to-day work will revolve around enabling continuous delivery and ensuring infrastructure stability for our enterprise clients. You will spend a significant portion of your time designing and refining CI/CD pipelines, transforming manual deployment processes into automated, repeatable workflows. This requires writing scripts, configuring orchestration tools, and setting up automated testing gates to catch errors before they reach production.

Collaboration is a massive part of this role. You will work side-by-side with the client's software developers to understand their application architecture and resource requirements. When a new feature is ready, you are responsible for ensuring the cloud infrastructure is provisioned correctly via Terraform or ARM templates, and that the deployment pipeline can handle the release smoothly. You will also work closely with QA teams to integrate testing into the deployment lifecycle.

Beyond deployments, you will act as a guardian of system reliability. This involves setting up comprehensive monitoring and alerting systems using tools like Prometheus, Grafana, or Datadog. When production incidents occur, you will be on the front lines, analyzing logs, diagnosing infrastructure bottlenecks, and implementing permanent fixes to prevent recurrence. Your goal is to create an environment where developers can push code confidently and operations run seamlessly.

To be a competitive candidate for the DevOps Engineer position at Aubay Spain, you need a solid foundation in cloud computing, automation, and system administration, paired with excellent communication skills.

• Must-have skills – Proven experience with major cloud providers, specifically AWS or Azure. Deep, hands-on knowledge of Terraform for provisioning infrastructure. Expertise in building and managing CI/CD pipelines using tools like Jenkins, GitLab CI, or Azure DevOps. Strong Linux administration skills and proficiency in at least one scripting language (Bash, Python). Fluent English is strictly required, as you will be interacting with international teams and clients.
• Nice-to-have skills – Experience with container orchestration, particularly Kubernetes (EKS, AKS). Familiarity with configuration management tools like Ansible. Knowledge of modern monitoring and observability stacks (Prometheus, ELK stack, Datadog). Previous experience working in an IT consultancy or agency model is highly valued.
• Experience level – Aubay typically looks for mid-to-senior level engineers for these roles, generally requiring 3 to 5+ years of dedicated DevOps or Cloud Engineering experience. A background in software engineering or traditional system administration is common and beneficial.
• Soft skills – Exceptional stakeholder management and communication skills. You must be able to push back constructively when clients propose unscalable solutions, while maintaining a positive, collaborative relationship. Adaptability and a proactive problem-solving mindset are essential.

Q: How difficult is the online technical test on platforms like CodinGame? The online assessment is generally considered to be of average difficulty. It consists mostly of multiple-choice questions that test your foundational knowledge of DevOps principles, Linux, networking, and basic scripting. If you have a solid grasp of the fundamentals, you should pass comfortably.

Q: What is the dynamic between Aubay Spain and the client during the interview process? Aubay acts as your employer, but you will be consulting for a specific client. The initial rounds ensure you meet Aubay's high internal standards. The final round is with the client to ensure you are a perfect fit for their specific project, tech stack, and team culture.

Q: Does Aubay Spain sponsor visas or assist with relocation? Yes. Candidates frequently report positive experiences with Aubay's legal and HR departments regarding relocation. If you are applying from outside of Spain or Portugal (such as Brazil or Nigeria), Aubay typically handles the visa documentation, flight bookings, and provides logistical support for your move.

Q: How much should I prepare for the resume deep-dive interview? You should prepare extensively. Aubay technical specialists will ask pointed questions about the specific technologies you list on your resume. If you list Terraform, expect to be asked about state management; if you list AWS, expect architecture questions. Never list a technology you cannot confidently discuss in detail.

Q: What is the typical timeline from the first interview to an offer? The process is usually well-organized and moves steadily. However, because it involves coordinating with external client schedules for the final interview, the entire process typically takes between three to five weeks from the initial recruiter screen to a formal offer.

• Master Your Own Resume: The Aubay technical interview is heavily tailored to your stated experience. Review every project and technology on your resume and prepare a brief, technical narrative for each. Be ready to explain the why behind your architectural choices, not just the how.
• Brush Up on English Fluency: As a consultant working with international clients, your ability to communicate complex ideas in English is just as important as your coding skills. Practice speaking your technical answers aloud to ensure clarity and confidence.

• Adopt a Client-First Mindset: During the final client interview, focus on how your skills will solve their business problems. Demonstrate empathy for the challenges their development teams face, and frame your DevOps practices as solutions that will make their lives easier and their products more reliable.
• Be Honest About Your Limits: If you are asked about a specific Azure service or CI/CD tool you haven't used, do not guess. Acknowledge your lack of direct experience, briefly mention a similar tool you do know, and emphasize your proven ability to learn new technologies quickly.

• Prepare for Whiteboarding or Architecture Discussions: While heavy live-coding is rare, you may be asked to verbally design a deployment pipeline or cloud architecture. Practice sketching out high-level system designs and explaining the flow of data and code from commit to production.
