Essential Interview Questions for Site Reliability Engineer
How would you approach troubleshooting a sudden increase in latency for a critical service?
I would start by gathering as much information as possible, including monitoring dashboards, recent deployments, and any relevant logs. I would then try to correlate the increase in latency with any recent changes or events. After identifying potential causes, I would use tools like tcpdump or strace to diagnose the root cause. Finally, I would implement a fix and monitor the service to ensure that the latency returns to normal. A post incident review would help prevent recurrence.Describe your experience with configuration management tools such as Ansible, Puppet, or Chef.
I have extensive experience with Ansible. I have used it to automate the deployment and configuration of servers, applications, and network devices. I have also used Ansible to enforce configuration standards and ensure consistency across the infrastructure. My experience includes writing playbooks, creating roles, and managing inventories. Furthermore, I have integrated Ansible with CI/CD pipelines to automate infrastructure provisioning.How do you approach monitoring and alerting for a large scale distributed system?
For a large scale distributed system, I would implement a comprehensive monitoring and alerting strategy using tools like Prometheus, Grafana, and Alertmanager. I would define key performance indicators (KPIs) for each service and set up alerts to notify me of any anomalies or deviations from the norm. I would also implement synthetic monitoring to proactively detect issues before they impact users. Effective alerting should be actionable and avoid alert fatigue.Explain your understanding of the CAP theorem and how it applies to distributed systems.
The CAP theorem states that a distributed system can only guarantee two out of the following three properties: Consistency, Availability, and Partition Tolerance. Consistency means that every read receives the most recent write or an error. Availability means that every request receives a non error response, without guarantee that it contains the most recent write. Partition Tolerance means that the system continues to operate despite arbitrary partitioning due to network failures. In practice, distributed systems must tolerate network partitions, so a choice must be made between consistency and availability.How do you handle on call responsibilities and prioritize incidents?
When on call, I ensure I am reachable and responsive. I prioritize incidents based on their impact and urgency, using established severity levels. I follow documented incident response procedures and collaborate with other teams to resolve issues quickly. I also participate in post incident reviews to identify root causes and prevent future occurrences. Furthermore, I ensure proper documentation of incidents and their resolutions.Describe a time when you had to debug a complex performance issue in a production environment.
In a previous role, we experienced intermittent slowdowns in our primary database. To address this, I used a combination of profiling tools, query analysis, and database logs to identify long running queries and inefficient indexes. I worked with the database team to optimize the queries and add missing indexes. We also implemented connection pooling and caching strategies to reduce the load on the database. These changes resulted in a significant improvement in performance and stability.Recommended Job Offers for You
