I have an upcoming Python interview where they're going to dive deep into OOP concepts. I'm a bit nervous and really need this job since I'm facing financial issues. Can anyone suggest what specific OOP questions I might encounter or what topics I should prepare for?

I recommend checking out 'Fluent Python' by Luciano Ramalho. It's a comprehensive resource that covers a lot of details about Python and OOP. Reading it thoroughly should give you a solid foundation.
It's tough to say exactly what they'll ask, but if you're comfortable with Python and have experience with classes and inheritance, you should be okay. Just brush up on the theory behind the concepts, and you’ll feel more confident going in.
I came across some solid questions that might help you prepare:
1. **Classes and Objects**: How do you define a class and create an object in Python? Can you provide an example using an __init__ method?
2. **Inheritance**: What’s the mechanism for inheritance in Python? Can you show how to create a base class and a subclass that modifies one of its methods?
3. **Encapsulation**: Since Python doesn't strictly enforce access modifiers, how can you manage encapsulation, and what naming conventions are usually followed?
4. **Polymorphism**: Can you explain what polymorphism means in Python and how it applies to built-in functions and custom classes?
5. **Special Methods**: What are dunder methods, and how can they alter the behavior of Python objects?
Absolutely, it's a fantastic book! You'll learn a lot from it.
