Grokking the Low Level Design Interview Using OOD Principles
This object oriented design course from Educative provides strategic preparation for technical interviews at leading technology companies. The 5-hour interactive programme focuses specifically on breaking down complex system design problems using established OOD principles and patterns. Students work through real-world scenarios commonly presented in interviews, learning to architect scalable systems whilst demonstrating solid object-oriented thinking. The browser-based format requires no software installation, allowing immediate access to coding environments and design exercises. With a 4.6 rating, this course bridges theoretical knowledge with practical interview performance, covering essential design patterns, SOLID principles, and system architecture decisions that interviewers expect candidates to articulate clearly.

What This Computing & IT Course Covers
The course covers fundamental object oriented design patterns including Singleton, Factory, Observer, and Strategy patterns alongside SOLID principles for maintainable code architecture. Students learn to design common systems like parking garages, chat applications, and booking platforms using proper inheritance hierarchies, encapsulation strategies, and polymorphism. Key topics include class relationships, interface design, and dependency management through practical system design challenges.
Educative delivers content through interactive coding environments where students implement actual object oriented design solutions in real-time. Each design problem includes step-by-step breakdowns, allowing learners to practice system requirements gathering, class diagram creation, and code implementation. The platform provides immediate feedback on design decisions, helping students understand trade-offs between different architectural approaches and refine their problem-solving methodology.
These object oriented design skills directly apply to software engineering roles requiring system architecture capabilities. The interview-focused approach prepares candidates for technical rounds at major technology companies where OOD questions are standard. The curriculum draws on principles of object-oriented design, applied to real-world scenarios.
