Senior Backend Engineer Interview Guide
A comprehensive, open-source senior backend engineer interview preparation knowledge base covering CS fundamentals, system design, infrastructure, and 160+ structured topic files.

Project Overview
A Markdown knowledge repository designed as a structured interview prep guide for senior backend engineers. Covers 6 major areas: CS Fundamentals (data structures, algorithms, OS, networking), Backend Development (API design, databases, caching, message queues), System Design & Architecture (design patterns, microservices, large-scale case studies), Infrastructure & DevOps (cloud, containers, CI/CD, observability), Specialized Topics (security, testing), and Frontend Development. Each topic file includes a difficulty rating (1–10), tags, detailed theory explanation, and optional Go code examples. A QUIZ directory enables self-assessment.
Technical Challenges & Solutions
Content Depth vs. Breadth Balance
Interview guides often go too broad (surface-level bullet points) or too deep (textbook-level) — neither is useful for targeted interview prep.
Consistent Knowledge Structure
With 160+ topic files contributed over time, inconsistency in format and depth degrades the guide's usefulness.
Learnings
Creating and curating this guide systematically forced me to articulate knowledge I had applied intuitively — especially in system design, database internals, and distributed systems. The process of writing clear, accurate explanations for 160+ topics significantly sharpened my own understanding and my ability to communicate technical concepts.
