7 top Site Reliability Engineer SRE job interview questions

If you have experience with version control systems like Git, explain what kind of projects you’ve worked on and how you’ve used the system. If you don’t have any direct experience, talk about related skills or experiences that demonstrate your ability to learn quickly and manage complex codebases. You can also mention any open source contributions you’ve made using version control systems.

So, it’s important to speak to why you’re excited about building services that improve system reliability and lead to greater customer and employee happiness. Technical upgrades provide enhanced functionality, which can allow employees to optimize their workflow and maximize productivity. Over time, qualified SREs gain a wealth of knowledge in the complexities of system production and development.

What’s the difference between SRE and DevOps?

Use these questions to assess a candidate’s personal traits and cognitive skills. In addition to development and IT troubleshooting responsibilities, this role requires top-notch communication skills. If you want to learn more about site reliability engineering, you can check out the free online book from the Google team. High expectations from users role are that companies need SREs to help them meet higher reliability expectations.

Site Reliability Engineer questions

Scrum is for software development teams that are working on one or a few products. The service-level purpose, or SLO, is a statistic agreed on by the company and their customer concerning what goal the task will undoubtedly attain. This is part of the service level arrangement, which is a run-down neighborhood. Usual standards used to establish the SLO include response time, throughput, frequency, and other service delivery metrics. With these tools in place, I can easily spot anomalies in the data and then quickly drill down into the source of the issue using tracing and log data.

Name three types of databases and an example of each. Name some you have used.

It will also help determine if the candidate is able to effectively collaborate with other teams and stakeholders. Site Reliability Engineers need to have experience with a variety of IT systems and technologies, including databases. This question will help the interviewer understand your level of understanding of the technology and whether you have the skills needed to succeed in the role. To answer this question, I would start by talking about my approach to troubleshooting network connectivity issues. I like to begin by gathering as much information as possible from the user who is experiencing the issue and any logs that might be available.

  • The interviewer wants to know that you have the experience and knowledge necessary to develop and implement automation processes, as this will be a key part of your job.
  • A collection of guidelines called data structures is used by computers to organize and store data.
  • For example, you could talk about how you would establish a communication plan with clear roles and responsibilities for each team.
  • The application was divided into microservices and the deployment time reduced from 4 hours to 20 minutes.
  • When the server pays attention to web traffic, LISTEN, SYNC-SENT after a demand is sent out.

Describe the Situation, talk about the Task you were trying to complete, discuss the Actions you took, and finish with the Results you attained. Here, you should focus on the methods and techniques that you use to identify performance issues and optimize system performance. Talk about how you use monitoring tools, such as Nagios or Prometheus, to track system performance over time. Explain any other techniques that you have used in the past, such as load testing, capacity planning, and optimization of database queries.

How well do you understand Linux Shell?

There are many ways to run a production meeting, depending on the location of team members and the scope. What this question gets to is your candidate’s leadership ability and resourcefulness in moving a project through the pipeline. Development is a highly collaborative process, requiring a number of teams and clients to work together.

Site Reliability Engineer questions

Overall, my collaborative approach with development teams has led to a more reliable project outcome, with a 95% reduction in reliability-related issues post-production. I believe this approach is highly effective and plays a crucial role in ensuring project success. I also implemented robust monitoring and alerting systems that provided early warning of system outages and enabled quick incident response. A site reliability engineering role focuses on managing the systems belonging to core infrastructure inclined and applicable to the production environment. On the other hand, DevOps is used to inculcate automation and simplification in system development teams and their non-computing parameters. Ultimately, the goal of these two teams is to reduce the gap between development and operations.

What are the roles of SRE?

Users won’t have to think about data loss in the event of a drive failure thanks to this additional protection. It makes it possible for devices connected to the same network to discover each other’s MAC address, IP address, as well as other network details. In order for network devices to communicate with one another, it is used to dynamically assign An ip address to those devices. When you enter a URL (such as ) into the browser, your computer requests the IP address connected with that web address from the DNS resolver. The IP address of a local machine or another server which has been set up to return that specific IP address is then returned to the browser by the DNS resolver.

Tell me about a time when you removed a performance bottleneck and streamlined system operations. Use these questions to determine how a candidate handled situations in the past. Site reliability engineering and DevOps share a close relationship — but it’s not always clear what, exactly, that relationship is. Instead, talk about your strengths in terms of what you can do for the organization. Site Reliability Engineering (SRE) is in charge of putting the product that the Core Development team made into action.

It’s also a role where non-technical skills are just as important as tech IQ. Site reliability engineering (SRE) is a rapidly changing field, and staying up-to-date is critical for success. Companies need SREs who know the latest technologies and trends in the field and can apply them to their work.

This article will help you learn in greater detail what you need to know to not only be successful, but one of the best SREs. RAID 0 strictly emphasizes performance while RAID 5 introduces fault tolerance at the expense of somewhat lower performance. All of these are important, but you are really looking at whether the candidate understands the big picture and how they communicate it to you. Ultimately, you aren’t looking necessarily for comprehensive knowledge, but rather whether they can name the main points of interest and do so with clear definitions. It’s a data structure where each data element is a separate element in a list. The list starts with a head, which is a reference to the first node in the list.
