This course will help you to discover creating modular, flexible, and reusable software, by applying object-oriented design principles and guidelines. It covers all the important object-oriented Design Principles and Design Patterns.

Why you should learn Object-Oriented Design & Design Patterns?

The object-oriented design has always been a critical part of the software engineering interview process. These Object-Oriented design (Low-level Design) questions (like Design a Movie Ticket Booking System, Design a Chess Game etc.) are about demonstrating that you understand how to create elegant, maintainable object-oriented code. Most of the engineers struggle with these questions, because of

  1. Their lack of experience in laying down the design of a complex system,
  2. The unstructured and open-ended nature of these types of problems that don't have a standard answer.
This course is a complete guide to master Object-oriented design interviews. It not only has a set of carefully handpicked case studies, which have been repeatedly asked at the top tech companies but covers all the important object-oriented Design Principles and Design Patterns.
