Ace your SRE interview. This video covers Site Reliability Engineer interview questions and answers for freshers and experienced candidates. Learn about real time scenarios asked in product based MNCs and more. We'll cover everything from basic to advanced and scenario-based questions to help you clear SRE interview.
👉 Below are the concepts we covered in this video on Top SRE Interview Questions and Answers:
00:00:00 Introduction
00:01:15 Describe your experience with networking, security, and infrastructure-related tasks.
00:03:15 The state file is locked and you cannot run Terraform apply because a previous process died. How do you fix it?
00:04:04 How do you embed security into the DevOps and SRE lifecycle using DevSecOps practices?
00:05:01 Your team needs to manage Terraform state for 50 microservices across 3 environments. How do you organize state?
00:06:01 You receive a high-severity alert in Splunk: latency on the primary checkout service has spiked by 400%, and the error rate is climbing. You look at the traces, and the backend SQL database CPU is at 100%. The database team says no deployments or schema changes have occurred. Walk me through your immediate actions.
00:08:10 You need to refactor a large, monolithic Terraform state file into smaller state files. How would you do this safely?
00:09:01 You are designing an Amazon EKS environment for an important application. To minimize the crash radius of infrastructure failures, you have adopted a cell-based architecture where each cell is an independent cluster limited to a single Availability Zone (AZ). How do you configure AWS networking and traffic routing to guarantee that a failure in one AZ cannot fall into the others?
00:10:45 You run a high-availability Kubernetes cluster spread across 3 Availability Zones. The nodes themselves report they are healthy, but kubectl commands are timing out, deployments are hanging, and controller managers are crash-looping. You suspect a control plane issue. What is the most likely culprit, and how do you confirm and fix it?
00:12:53 Your CI/CD pipelines running in a SaaS provider (like GitHub Actions or GitLab) need to dynamically provision infrastructure across AWS, GCP, and Azure. The security team has flagged that long-lived, highly privileged static API keys for all three clouds are sitting in the CI/CD environment variables, posing a massive security risk. How do you fix this permanently?
00:14:44 Design a cloud architecture for a three-tier application.
00:16:48 Can you describe your approach to escalation management in client success?
00:18:29 Your company relies on a self-hosted Large Language Model (LLM) for a customer-facing support chatbot. Suddenly, inference latency spikes from 2 seconds to 15 seconds. You check the cluster, and GPU utilization is pegged at 100% due to a viral marketing campaign. You attempt to auto-scale, but the cloud provider returns an InsufficientCapacityException there are no more GPUs available in your region. How do you restore service?
00:20:27 How do you integrate an application with observability tools like Grafana?
00:22:05 Design a CI/CD pipeline for an application deployed on EC2 in production, ensuring scalability, reliability, and automated testing.
00:24:26 Describe the process of creating and managing AWS EC2 instances using Terraform.
