Site Reliability Engineer Interview Questions
How do you support services before they go live? Are you familiar with activities such as system design consulting, capacity planning, and launch reviews?

Sample answer to the question

Before services go live, I support them by providing system design consulting, conducting capacity planning, and conducting launch reviews. I have experience in working closely with development teams to ensure that infrastructure builds are integrated seamlessly with application deployment processes. To maintain high availability, performance, security, and scalability, I employ a software engineering mindset to system administration tasks. This includes automating systems and infrastructure tasks through coding/scripting. I also have a deep understanding of monitoring solutions and APM tools to proactively identify and address any issues that may arise.

A more solid answer

In my role as a Site Reliability Engineer, I have extensive experience supporting services before they go live. For system design consulting, I work closely with development teams to ensure that the infrastructure is designed to meet the specific requirements of the services. This includes analyzing the scalability, security, and performance aspects. I also conduct capacity planning by evaluating the expected traffic and resource requirements to ensure that the services can handle the anticipated load. In terms of launch reviews, I collaborate with cross-functional teams to perform thorough testing and identify potential issues before the services are released to users. Additionally, I have hands-on experience with continuous integration and deployment (CI/CD) pipelines and DevOps practices, allowing me to automate the deployment process and ensure seamless releases.

Why this is a more solid answer:

The solid answer provides more specific details about the candidate's experience in supporting services before they go live. It mentions working closely with development teams for system design consulting and conducting capacity planning. It also highlights collaboration with cross-functional teams for launch reviews. The answer addresses the evaluation areas by mentioning the candidate's hands-on experience with continuous integration and deployment (CI/CD) pipelines and DevOps practices. However, it can be further improved by providing examples or concrete projects that showcase the candidate's skills and accomplishments.

An exceptional answer

Supporting services before they go live is a crucial aspect of my role as a Senior Site Reliability Engineer. In terms of system design consulting, I have been involved in multiple projects where I collaborated with development teams to design highly scalable, secure, and performant infrastructures. For example, in one project, I led the design of a microservices architecture using Kubernetes and Docker containers, ensuring fault tolerance and efficient resource utilization. During the capacity planning phase, I conducted extensive load testing and analysis to accurately estimate the required resources for the services, enabling seamless scalability. In terms of launch reviews, I spearheaded cross-functional reviews to identify potential bottlenecks or performance issues. One notable achievement was identifying a database query optimization opportunity that significantly improved response times. Additionally, I have implemented robust CI/CD pipelines using tools like Jenkins and GitLab, automating the deployment process and enabling continuous delivery. Overall, my experience and expertise in system design consulting, capacity planning, and launch reviews make me highly adept at supporting services before they go live.

Why this is an exceptional answer:

The exceptional answer provides detailed examples and accomplishments that showcase the candidate's expertise and experience in supporting services before they go live. It highlights specific projects and their outcomes, such as leading the design of a microservices architecture and identifying database query optimizations. The answer also emphasizes the candidate's proficiency in implementing CI/CD pipelines using Jenkins and GitLab. By providing concrete examples, the candidate demonstrates their ability to effectively support services before they go live. This answer expands on the solid answer by including specific projects and achievements.
