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
