I create this repository as extended version of Grokking the Object Oriented Design Interview course. I add example-codes part for better understanding.

1. All codes except OOP basics section are not executable.
2. I use Python for coding demonstration.
3. I try to write error free codes that's why in many class and function i just use None or pass
4. For practice I left coding section empty of Facebook's Extended Requirement section.
