The Complete SDE Roadmap for Software Engineering Interview Success
SDE Roadmap is a comprehensive, free platform designed to help software engineers prepare for technical interviews at top tech companies. Whether you are targeting Amazon, Google, Meta, Microsoft, or any other product-based company, our structured roadmap covers every topic you need to master — from data structures and algorithms to system design, backend engineering, and frontend development.
Our platform is built around seven mastery tracks, each containing carefully curated phases that take you from fundamentals to advanced interview-ready topics. The DSA Roadmap covers 8 phases spanning arrays, strings, trees, graphs, dynamic programming, and advanced data structures. The Java Mastery Track includes 11 phases covering OOP, Collections, Stream API, multithreading, and JVM internals. The SQL Track takes you through 9 phases from basic queries to window functions, optimization, and complex joins.
For backend engineers, our Backend Engineering Track covers 20 phases including REST API development, Spring Boot, database integration, authentication, caching, message queues, and production deployment. The MERN Backend Track provides 18 phases dedicated to Node.js, Express.js, MongoDB, Mongoose, Redis, WebSockets, and real-time application development. Frontend developers can follow our 14-phase track covering HTML, CSS, JavaScript, TypeScript, React, performance optimization, accessibility, and testing.
The System Design Track is one of the most comprehensive resources available online, covering 11 phases from fundamental concepts like CAP theorem, load balancing, and caching strategies to detailed case studies of URL shorteners, chat systems, ride-sharing platforms, and e-commerce architectures. You will learn how to design systems like a senior engineer, with practical frameworks for HLD and LLD interviews.
What sets SDE Roadmap apart is our commitment to depth and clarity. Every topic includes detailed explanations, visual diagrams, code examples, and curated practice problems. Our 250+ practice problems range from easy to hard, each with brute force and optimal solutions, complexity analysis, and edge case coverage. The platform also includes cheat sheets for quick revision, an OA Practice Timer that simulates the Amazon Online Assessment experience, and a personal dashboard to track your progress across all tracks.
