ING Hubs Spain DevOps Engineer interview questions & guide 2026

The following questions represent patterns observed in recent ING Hubs Spain interviews. These are designed to test your depth of knowledge across infrastructure, automation, and collaborative problem-solving.

Technical Infrastructure & Cloud

These questions assess your hands-on experience with cloud providers and your ability to design resilient infrastructure.

• How do you use Terraform to provision secure access to cloud platforms like GCP?
• Can you describe the process of managing infrastructure components in a hybrid cloud environment?

Preparation for ING Hubs Spain should be structured around demonstrating both deep technical proficiency and a collaborative mindset. You must be prepared to articulate not just what tools you use, but why you chose them and how they align with business objectives.

Role-related Knowledge – You need to demonstrate mastery of the core DevOps stack, specifically Terraform, containerization, and cloud-native services. Interviewers will look for your ability to explain the underlying principles of these tools rather than just your familiarity with their commands.

Problem-solving Ability – We focus on your methodology. When presented with a scenario, clearly state your assumptions, the trade-offs you considered, and how you arrived at your final solution.

Communication & Influence – As a DevOps Engineer, you will frequently act as a consultant to development teams. Be ready to explain complex technical concepts to non-technical stakeholders and demonstrate how you drive consensus.

The interview journey at ING Hubs Spain is designed to evaluate your technical depth, your ability to handle complex scenarios, and your alignment with our engineering culture. Typically, the process begins with an initial screening followed by a technical assessment. You should expect a mix of theoretical quizzes, scenario-based technical discussions, and interviews with leadership where you will discuss your past projects and architectural decisions.

The pace can be deliberate, often involving multiple weeks between stages as we ensure a thorough assessment. We value transparency and rigor, so expect the interviewers to dig deep into the "how" and "why" of your previous work. The process is not just about passing a test; it is about finding a candidate who can contribute to our long-term technical vision.

The timeline above represents the typical progression from initial screening to final leadership interviews. Candidates should interpret these stages as a funnel; each round builds upon the last, moving from general competency to specific, high-stakes architectural scenarios. Manage your energy by preparing for intense technical deep-dives in the middle rounds, as these are often the most demanding part of the process.

Cloud Architecture and Provisioning

We prioritize candidates who understand the lifecycle of cloud infrastructure. You will be evaluated on your ability to design for scalability, security, and cost-effectiveness.

Be ready to go over:

• Infrastructure as Code (IaC) – Best practices for using Terraform or similar tools to manage state and modules.
• Security Compliance – Implementing "Security by Design" within your deployment pipelines.

As a DevOps Engineer, your primary objective is to enable product teams to move faster while maintaining the integrity of our systems. You will spend a significant portion of your time designing and maintaining infrastructure as code, ensuring that our deployment pipelines are secure, efficient, and reliable. You will also act as an internal consultant, helping development teams adopt cloud-native practices and troubleshooting complex issues that span across the stack.

Collaboration is key; you will frequently work with platform architects, security teams, and application developers. Whether it is standardizing how we deploy to GCP or mentoring junior engineers on best practices, your role is to foster an environment of continuous improvement. You will be expected to own your initiatives from design through to production deployment, ensuring that every change meets the high reliability standards of ING Hubs Spain.

To be competitive for this position, you need a solid foundation in cloud infrastructure and a proactive approach to automation.

• Must-have skills: Proficient in Terraform, experience with GCP or other major cloud providers, strong understanding of CI/CD pipelines, and deep experience with containerization technologies.
• Nice-to-have skills: Experience with AI-driven automation, familiarity with site reliability engineering (SRE) principles, and contributions to open-source DevOps projects.
• Experience level: We typically look for engineers who have demonstrated success in managing large-scale, production-grade systems in a regulated industry.

Q: How long does the entire interview process usually take? The process can vary, but generally, it spans several weeks due to the multi-stage nature of our evaluation. Expect clear communication from our recruitment team, though feedback timelines can sometimes be longer for high-volume roles.

Q: What is the most important trait for a successful candidate? Beyond technical skills, we look for "Engineering Ownership." Successful candidates are those who take responsibility for their work, anticipate potential failures, and strive to improve the systems they touch.

Q: Is there a coding test involved? While not all roles require a traditional whiteboarding algorithm test, you should expect technical assessments that involve scripting, infrastructure configuration, or architectural design.

Q: How should I prepare for the "quiz-style" technical round? Focus on understanding the core principles of networking, Linux internals, and cloud security. These rounds test your breadth of knowledge across the entire DevOps domain.

• Contextualize your answers: Always link your technical choices back to the business impact. For example, explain how a specific Terraform change improved deployment speed or reduced security risk.
• Prepare for follow-ups: Expect interviewers to drill down into the "why" behind your technical decisions. Don't just state a tool; explain why it was the right fit for that specific project.
• Structure your behavioral answers: Use the STAR method (Situation, Task, Action, Result) to keep your answers concise and impactful.
• Stay current: Be prepared to discuss recent trends in the DevOps space, especially regarding AI agents and cloud-native security, as these are hot topics at ING Hubs Spain.
