A comprehensive, structured library of Q&A-style notes, scenario-based problems, and real-world troubleshooting guides designed to help you confidently prepare for DevOps, Cloud, and Site Reliability Engineering (SRE) interviews.
The DevOps Interview Preparation Hub is a curated, practical resource covering the entire interview lifecycle. Unlike generic question lists, this repository helps you prepare for every stage—from your initial HR screening to advanced technical system design and live production troubleshooting simulations.
All materials are written in plain, readable Markdown. This makes them easy to search, read offline, or customize for your personal study needs.
- Comprehensive Coverage: Includes foundational concepts, tool-specific Q&As, and HR behavioral preparation.
- Real-World Scenarios: Step-by-step breakdowns of actual system outages and production-style troubleshooting.
- Targeted Preparation: Specific guides for various experience levels and company-specific mock interviews.
- Easy Navigation: Organized clearly into folders by topic and difficulty.

We recommend a 4-phase study plan to build your confidence step-by-step:
| Phase | Focus | Recommended Folders |
|---|---|---|
| Phase 1: Fundamentals | Core Linux, AWS, Git, and basic HR questions | Core_Topic_Q&A/, Hr_Interview_QA/ |
| Phase 2: Core Tools | Containerization, Kubernetes, Terraform, and scripting | Core_Topic_Q&A/ |
| Phase 3: Observability | Monitoring, logging, and real-world troubleshooting | Real_World_Scenario_Based_Troubleshooting_Q&A/ |
| Phase 4: Simulations | Mixed-domain questions, mock interviews, and scenarios | Rapid_fire_Mock_Interview_Q&A/, Production_Style_Question_Sets/ |
You can quickly search the library for specific tools or concepts (e.g., "Kubernetes", "OOMKill", "Terraform state").
- In VS Code: Press
Ctrl + Shift + Fand type your search term. - In the Terminal: Run the following search commands:
# Search using grep grep -r "EKS troubleshooting" . # Search using ripgrep (faster) rg "autoscaling" .

To keep the repository organized, searchable, and easy to navigate, we utilize a standardized tagging system across all markdown files.
These tags classify questions and scenarios by their primary tool or technology domain:
[Linux]: Operating system architecture, system administration, and basic shell commands.[AWS]: Cloud provider services (e.g., EC2, IAM, S3, VPC, EKS).[Kubernetes]: Container orchestration concepts, scheduling, networking, and deployment workloads.[Docker]: Containerization basics, writing Dockerfiles, and managing runtimes.[Terraform]: Infrastructure as Code (IaC) syntax, state storage, locking, and workspaces.[CI/CD]: Continuous Integration and Continuous Deployment pipelines (Jenkins, GitHub Actions, GitLab CI).[Monitoring]: Application performance management, metric collection, and log analysis (Prometheus, Grafana, CloudWatch, Datadog).
These tags indicate the target experience level for specific question banks:
[Fresher / Entry-Level]: Core definitions and basic setup questions (0-1 year experience).[Junior]: Day-to-day operational tasks, syntax, and common commands (1-2 years experience).[Mid-Level]: Deeper concepts including architecture choices and optimization (2-4 years experience).[Senior]: Advanced design principles, disaster recovery, cost optimization, and mentoring.[SRE]: High-availability practices, error budgets, SLAs, and performance troubleshooting.
These tags indicate the structure of the content:
[Q&A]: Structured question-and-answer format for straight revisions.[Scenario]: Theoretical production outage problems requiring system-design analysis.[Troubleshooting]: Practical, step-by-step resolution logs based on real-world incidents.[Mock]: Full mock interviews mapped to specific hiring processes (e.g., Honeywell, TCS, Worldpay).
This repository uses standard Git semantic version tags (e.g., v1.0.0) to mark major documentation releases.
- Example: To view/clone the repository exactly as it was during release version
