: Object Oriented Design & Design Patterns Live

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 (likeDesign 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.

How this course will help you to crack Interviews?

  • Each concept is explained focusing the Interviews of tech giants like Google, Amazon, Microsoft, Uber, etc.
  • Mock Interview session (taken by the course mentor) will help you to feel the heat of actual interviews and you will be given the proper feedback after the interview.
  • This course is designed and reviewed by the developers/Architects of Microsoft, Amazon, and Adobe
