Object-Oriented Design Interview Courses for Software Engineers

Object-Oriented Design (OOD) interviews are a staple in the hiring process for software engineers—from new grads to senior roles. But many candidates walk into them underprepared, unsure how to structure their approach or apply design principles effectively.

Our Object-Oriented Design interview prep courses are here to fix that. Whether you're just learning OOD or aiming to level up your architectural thinking, we’ve built a guided curriculum that takes you from zero to confident.


🧱 Course Breakdown

🟢 Object-Oriented Design Basics

Best for: New grads or self-taught developers

You’ll learn:

  • How to identify objects, attributes, and responsibilities
  • Fundamentals of class design and relationships (composition vs. inheritance)
  • Core OOD principles: SOLID, encapsulation, abstraction, polymorphism

Includes:

  • Simple modeling questions (e.g., Design a Library System, Parking Lot)
  • Interactive class diagrams and guided breakdowns
  • Step-by-step design thinking framework

🟡 Design Patterns & Mid-Level Interview Prep

Best for: SWE I/II or intermediate developers

You’ll dive deeper into:

  • Common OOD patterns: Strategy, Observer, Factory, Decorator
  • How and when to use interfaces, abstract classes, and modular architecture
  • Building reusable, testable code for real-world interview questions

Features:

  • Pattern walkthroughs with interview-style questions
  • Code examples in Python/Java
  • Quizzes and diagrams to reinforce learning

🔴 Advanced Object-Oriented Design Scenarios

Best for: Senior engineers and system designers

This course helps you:

  • Model complex systems like game engines, trading platforms, or schedulers
  • Apply extensibility and performance trade-offs in design
  • Integrate OOD with system architecture thinking

Includes:

  • Case studies from top tech company interviews
  • Peer-reviewed design reviews
  • Tips on communication and diagramming in whiteboard interview

🔁 Built for Real Interviews

All courses include:

  • Role-specific OOD questions from FAANG and top startups
  • Guided solutions with design justification
  • UML diagrams, code examples, and class responsibilities
  • Evaluation checklists to help you self-review

📚 Learn by Doing

Our courses aren’t just lectures—they’re interactive design exercises with:

  • Hands-on practice
  • Mock interview prompts
  • Option to submit your solutions and compare with others

Don’t just read about OOD—practice it like it’s game day.
