Trustly DevOps Engineer interview questions & guide 2026

Our interview process is designed to balance technical competency with cultural alignment. The following questions reflect common patterns observed in recent candidate experiences.

Infrastructure as Code and State Management

These questions evaluate your proficiency in managing complex cloud environments and your ability to maintain consistency in team-based development.

• How do you organize and manage the state in Terraform (terraform.tfstate) in environments with multiple developers to ensure consistency and avoid conflicts?
• What strategies do you employ to handle resource drift in your infrastructure?

Preparation for a DevOps Engineer role at Trustly should focus on both your technical depth and your ability to communicate complex concepts clearly. You will be evaluated on your ability to translate business requirements into resilient technical solutions.

Technical Competency – We look for deep expertise in AWS and Terraform. You should be ready to discuss not just how to use these tools, but how you have used them to solve specific, real-world problems.

Problem-Solving Ability – Our interviewers want to see how you approach ambiguity. When presented with a system failure or an infrastructure challenge, walk us through your diagnostic process, your prioritization of fixes, and how you prevent future occurrences.

Communication and Language Skills – Because Trustly operates globally, clear communication is essential. Be prepared to discuss technical topics in English, as proficiency is a key requirement for effective cross-team collaboration.

The Trustly interview process is structured to be transparent and efficient. Generally, you can expect a sequence that includes an initial screening, technical deep-dives, and discussions regarding career alignment. We value organized, respectful communication and aim to keep the process moving at a steady pace.

Our approach emphasizes a comprehensive view of the candidate. We look beyond your resume to understand your motivations, your problem-solving style, and how you handle professional feedback. You will interact with both the People team and technical leadership, ensuring that you are a strong fit for both the team's culture and the technical demands of the role.

This visual timeline illustrates the typical progression from initial contact to final offer. Candidates should use this as a framework to manage their preparation time, ensuring they are ready for technical assessments early in the process and behavioral discussions in the later stages.

Infrastructure Automation

We prioritize candidates who can build scalable, repeatable, and secure infrastructure. You will be evaluated on your ability to write clean, maintainable code that manages cloud resources.

Be ready to go over:

• Terraform state management and remote backends.
• Secrets management within pipelines.

As a DevOps Engineer, your daily work involves maintaining the high availability of our payment infrastructure. You will be responsible for automating repetitive tasks, ensuring that our deployment pipelines are efficient, and collaborating with developers to ensure that applications are "production-ready."

You will work closely with other engineering teams to define infrastructure requirements and troubleshoot production incidents. A significant portion of your time will be dedicated to improving the developer experience by reducing friction in the deployment process and maintaining documentation for our infrastructure systems.

A strong candidate for this role possesses a solid foundation in cloud operations and a commitment to automation. We value practical experience that demonstrates your ability to handle production-grade systems.

• Must-have skills: Proficient experience with AWS, strong command of Terraform, and a high level of English proficiency.
• Nice-to-have skills: Experience with container orchestration (e.g., Kubernetes), scripting in Python or Go, and familiarity with security compliance standards.
• Experience: We look for candidates who have managed production environments where uptime and security were non-negotiable.

Q: How long does the process typically take? A: The process generally moves quickly, often spanning a few weeks from the initial screen to the final offer. We prioritize transparency, so you will stay informed of your status throughout.

Q: Is remote work an option? A: Trustly embraces flexible work environments, though this can vary by location and specific team needs. We recommend discussing this during your initial screening call.

Q: What makes a candidate stand out? A: Successful candidates demonstrate not just technical skills, but a "service-first" mindset. They show that they care about the stability of the platform and the productivity of their fellow engineers.

Q: How should I prepare for the technical interview? A: Focus on your past projects. Be prepared to explain the "why" behind your technical choices, not just the "how."

• Structure your answers: Use the STAR method (Situation, Task, Action, Result) when answering behavioral questions to keep your responses concise and impactful.
• Be honest about your gaps: If you don't know the answer to a highly specific technical question, explain how you would go about finding the answer. We value resourcefulness.
• Focus on security: Given our industry, always mention security considerations when discussing infrastructure architecture.

The role of DevOps Engineer at Trustly offers a unique opportunity to shape the infrastructure of a global leader in the fintech space. By focusing on your technical foundations in AWS and Terraform, while preparing to clearly articulate your past experiences, you will be well-positioned to succeed in our interview process.
