Abstract class is a class that cannot be instantiated and can have both abstract and non-abstract methods. Interface is a blueprint of a class that only has abstract methods.
OOPs concepts include inheritance, polymorphism, encapsulation, and abstraction. Example: Inheritance - a child class inheriting properties and methods from a parent class.
SOLID principles are Single Responsibility, Open-Closed, Liskov Substitution, Interface Segregation, and Dependency Inversion. Example: Open-Closed - classes should be open for extension but closed for modification.
Coding questions may include data structures, algorithms, and problem-solving skills.
