Design patterns are a way to solve commonly occurring problems in software engineering. They are reusable, tested solutions to certain software design problems. They are not cookie-cutter solutions, and developers using them can tailor them to address the specific problem at hand.

About the Author: NeetCode
NeetCode (neetcode.io) is the technical-interview-preparation platform of Navi (formerly an engineer at Google), behind one of the larger DSA-focused YouTube channels online. NeetCode's distinctive contribution is the curated NeetCode 150 and NeetCode 250 problem lists — pattern-grouped sets of LeetCode questions that have become a default reference for engineers preparing for the algorithm portion of senior tech-company interviews.
The course catalog covers algorithms and data structures in depth, system design for senior interviews, the OOP / design-patterns material that shows up in low-level design rounds, and the broader interview-prep landscape. Material is taught in Python, Java, and JavaScript with the same problem solved across multiple languages.
The CourseFlix listing under this source carries 7 NeetCode courses spanning that range. Material is paid; NeetCode runs on per-course or membership pricing on the original platform. Courses are aimed at engineers preparing for technical interviews at large tech companies.

Frequently asked questions
What are the prerequisites for this course?
To get the most out of this course, students should have a foundational understanding of object-oriented programming concepts. Familiarity with a programming language that supports object-oriented programming, such as Java, C++, or Python, will be beneficial. Prior experience with software development and basic design principles is also recommended.
What will I build or learn in this course?
The course focuses on understanding and applying object-oriented design patterns. Students will learn about various patterns such as Factory Method, Singleton, Builder, Adapter, Decorator, Facade, Strategy, and Observer. These patterns provide reusable solutions to common software design problems, enabling students to create more efficient and maintainable software.
Who is the target audience for this course?
This course is designed for software developers and engineers who want to deepen their understanding of design patterns and their applications in object-oriented programming. It is particularly useful for those looking to improve their software design skills and apply these patterns in real-world scenarios.
How does the depth of this course compare to similar courses?
The course provides a focused exploration of object-oriented design patterns, covering nine specific patterns in detail. It does not cover every possible pattern but offers a thorough examination of commonly used patterns, allowing students to gain a solid understanding of their applications and variations.
What specific tools or platforms are used in this course?
The course does not specify particular tools or platforms, as the design patterns taught are applicable across various programming languages and development environments. Students can apply the concepts learned using tools and platforms they are already familiar with.
What topics are not covered in this course?
The course does not cover every possible object-oriented design pattern, nor does it delve into language-specific implementations in depth. It also does not focus on non-object-oriented design patterns or advanced topics like concurrency patterns, which may require additional study beyond the course material.
What is the time commitment required for this course?
The course consists of nine lessons, each focusing on different design patterns. While the runtime of the course is not specified, students should allocate additional time for practice and application of the concepts learned to gain a comprehensive understanding of the material.
