ShopBack Site Reliability Engineer interview questions & guide 2026

Our interview process is designed to evaluate your technical proficiency, your ability to navigate complex systems, and your alignment with our collaborative culture. While specific questions may vary based on the team's current focus, the following categories represent the core areas of our evaluation.

Technical and Infrastructure Knowledge

These questions test your foundational knowledge of the tools and environments we use, such as AWS, Docker, and Kubernetes. Expect to discuss both theory and practical application.

• Why did you choose to use Docker in your previous projects?
• Can you explain how you manage Horizontal Pod Autoscaling (HPA) in Kubernetes?

Preparation at ShopBack should be focused on depth and clarity. You should be prepared to discuss every detail listed on your CV, as interviewers will use your past experiences as a foundation for technical inquiries.

Technical Competency – This covers your mastery of Linux/Unix environments, Bash scripting, and cloud infrastructure. You should be able to explain not just how a tool works, but why it was the right choice for your specific project.

System Thinking – We evaluate your ability to design and maintain reliable systems. You should demonstrate an understanding of how components interact, how to identify bottlenecks, and how to build for failure.

Problem-Solving Approach – We want to see your thought process. When faced with a hypothetical scenario or a past challenge, clearly articulate the steps you took to diagnose the issue, the alternatives you considered, and the reasoning behind your final decision.

Adaptability and Communication – As an SRE, you will often be the link between different teams. We assess how you communicate complex technical concepts and your willingness to learn new technologies when faced with unfamiliar tasks.

The interview process at ShopBack is structured to assess your technical depth and cultural fit in a systematic manner. While the exact number of rounds can vary, you should generally expect a progression from initial technical screening to deeper infrastructure discussions and, finally, a behavioral assessment. We value candidates who are transparent about their experience and who can demonstrate a systematic approach to problem-solving.

The pace is generally steady, and we prioritize candidates who can clearly articulate the trade-offs in their architectural decisions. We look for individuals who are not only technically strong but who also align with our values of ownership and collaboration.

This timeline outlines the typical stages a candidate moves through. You should treat the HackerRank assessment as a critical filter and use the technical interview rounds as a chance to showcase your depth of knowledge regarding AWS, Docker, and Kubernetes.

Infrastructure and Cloud Architecture

We focus on your ability to manage and scale cloud-native environments. A strong performance involves demonstrating an understanding of cost-efficiency, security, and high availability.

Be ready to go over:

• AWS Services – Understanding core services and how they integrate into a production stack.
• Containerization – Best practices for Docker image management and runtime security.

As a Site Reliability Engineer, your primary responsibility is to ensure the ShopBack platform remains stable and performant. You will spend a significant portion of your time managing and improving the infrastructure, which involves writing code to automate manual processes and managing cloud resources. You are expected to be hands-on with the deployment lifecycle, ensuring that code moves from development to production with minimal friction and maximum reliability.

Collaboration is essential. You will regularly interface with product and software engineering teams to define service-level objectives (SLOs) and improve system design. When production incidents occur, you are expected to lead the investigation, implement immediate fixes, and conduct post-mortems to prevent recurrence. This role requires a balance of reactive support and proactive engineering, where you identify areas of technical debt and systematically address them to enhance the overall stability of the platform.

A competitive candidate for the Site Reliability Engineer position will demonstrate a strong foundation in systems engineering and a clear understanding of modern cloud architectures.

• Must-have skills:

  • Proficiency in Linux/Unix and command-line interfaces.
  • Strong experience with AWS cloud infrastructure.
  • Hands-on knowledge of Docker and Kubernetes.
  • Ability to write scripts in Bash or Python for automation.
  • Familiarity with CI/CD concepts and tools.

• Nice-to-have skills:

  • Experience with infrastructure-as-code tools like Terraform.
  • Knowledge of monitoring tools (e.g., Prometheus, Grafana).
  • Understanding of database scaling and performance tuning.
  • Experience with service mesh or advanced networking in Kubernetes.

Q: How long does the entire interview process take? A: While timelines can vary, the process typically takes a few weeks from the initial screening to the final behavioral round. We strive to maintain momentum, though please be prepared for potential gaps between stages.

Q: What is the best way to prepare for the technical assessment? A: Focus on your fundamentals in Linux, Bash scripting, and general DevOps concepts. Since there may be a coding or scripting component, practice writing clean, efficient, and well-documented scripts.

Q: How much weight is placed on the behavioral interview? A: The behavioral interview is as important as the technical rounds. We want to ensure that you can work effectively within our team, communicate clearly during high-pressure situations, and align with our company culture.

Q: Does ShopBack value specific certifications? A: While certifications can be a good indicator of knowledge, we prioritize hands-on experience and the ability to solve real-world problems. Be ready to explain how you have applied your knowledge in actual production environments.

• Own your CV: Every project or technology mentioned on your resume is fair game. Be prepared to explain the "why" and "how" behind every bullet point.
• Focus on the "why": When discussing tools like Docker or Kubernetes, don't just list features. Explain the specific problems they solved for your previous teams.
• Practice articulating trade-offs: In system design, there is rarely one perfect answer. A strong candidate acknowledges the trade-offs (e.g., cost vs. performance) and explains why they chose a particular path.
• Be proactive in communication: If you have questions about the process or need clarity on a technical task, don't hesitate to ask your recruiter or interviewer.
