Global Relay Site Reliability Engineer interview questions & guide 2026

The questions below reflect patterns observed in recent Global Relay interview cycles. They are designed to assess your technical depth, command of the Linux environment, and your ability to solve problems under pressure. Use these as a baseline for your preparation, focusing on the underlying concepts rather than rote memorization.

Linux Fundamentals and Systems Administration

This category tests your day-to-day proficiency with the operating system, which is the backbone of the Global Relay infrastructure.

• What bash commands would you use to check disk space in a Linux environment?
• How do you identify the performance of a server, and which tools do you use to diagnose bottlenecks?

Preparation at Global Relay requires balancing deep technical knowledge with the ability to articulate your problem-solving process.

Technical Depth – You must be comfortable working at the terminal. Expect to be tested on your ability to manipulate files, monitor system health, and debug services without the help of a GUI.

Practical Application – Beyond knowing the commands, you need to explain the "why." If you mention a tool like Ansible or Terraform, be ready to discuss why it was the right choice for your specific project and how it improved the system's reliability.

Problem-Solving Mindset – When faced with a technical challenge or a coding task, vocalize your thoughts. Interviewers are looking for a logical approach to debugging and architectural design, not just the final output.

The interview process at Global Relay is generally structured to move from high-level experience checks to rigorous hands-on technical validation. You will typically start with a recruiter or liaison call to align on expectations, followed by a technical discussion with a hiring manager or senior engineer. The process often includes a practical, take-home coding or scripting assignment, followed by a final, more intensive round that may include group interviews or live coding sessions.

The rigor of the process is intended to ensure that you can function effectively in a high-pressure, production-focused environment. While the process is consistent, it can feel highly technical and at times "adhoc," focusing heavily on your ability to execute tasks in a Linux environment.

This timeline illustrates the progression from initial screening to final assessment. Use this to pace your study—prioritize mastering core Linux commands and scripting early, as these foundational skills appear in nearly every stage of the process.

Linux and Scripting Proficiency

This is the most critical area of your evaluation. You are expected to demonstrate fluency in bash and core command-line utilities. Strong candidates don't just know the commands; they understand how to chain them together to solve complex system-wide problems efficiently.

Be ready to go over:

• Text processing utilities like grep, awk, and sed.
• System monitoring and process management.

As a Site Reliability Engineer, your primary objective is to maintain the uptime and performance of Global Relay’s infrastructure. You will be expected to:

• Proactively monitor production systems and respond to incidents.
• Automate repetitive tasks to reduce manual intervention and human error.
• Collaborate with software engineers to ensure new features are deployable and scalable.
• Manage configuration and deployments using tools like Ansible and Terraform.
• Participate in on-call rotations and lead post-incident reviews to prevent future outages.

You will work closely with development teams to bridge the gap between code and operations, ensuring that the infrastructure is as robust as the software running on it.

A strong candidate for this role possesses a blend of deep system administration skills and a developer's mindset toward automation.

• Must-have skills:
• Expert-level knowledge of the Linux operating system.
• Proven experience with Bash scripting and at least one other language like Python or Groovy.
• Hands-on experience with Docker and Kubernetes.
• Strong understanding of infrastructure automation tools like Ansible.
• Nice-to-have skills:
• Experience with public cloud providers (AWS, Azure, GCP).
• Familiarity with CI/CD pipelines and tools like Jenkins.
• Strong understanding of network protocols and security certificates.

Q: How much time should I spend preparing? A: Dedicate at least two weeks to reviewing Linux internals, practicing bash scripting, and refreshing your knowledge of containerization. The technical interviews are straightforward but require high precision.

Q: Is the coding test difficult? A: The coding test is generally focused on basic logic (e.g., sequences or string manipulation). While the problems are not overly complex, they are timed; practice writing simple scripts under pressure.

Q: What is the company culture like? A: Global Relay operates in a high-stakes, compliance-heavy industry. You should expect a culture that prioritizes reliability, stability, and process-driven work.

Q: What is the typical interview timeline? A: From the initial recruiter call to a final decision, the process can take several weeks, including time for the take-home assessment and multiple rounds of technical interviews.

• Master the terminal: Do not rely on IDEs or GUIs during your technical rounds. You should be able to perform every task using core Linux commands.
• Explain your process: If you get stuck on a coding or system design question, talk through your thought process. Interviewers value how you approach a problem as much as the solution itself.
• Be ready for "Why": Don't just list tools you have used. Be prepared to explain the architectural trade-offs you made when choosing those tools.
• Research the domain: Understanding the compliance and data-archiving space will give you an edge, as it explains why Global Relay prioritizes certain stability metrics.

The Site Reliability Engineer role at Global Relay is a demanding but rewarding position that puts you at the heart of the company's technical infrastructure. Success in this role requires a solid foundation in Linux, a proactive approach to automation, and the ability to maintain calm under pressure.
