In C#, inheritance is a process in which one object acquires all the properties and behaviors of its parent object automatically. In such way, you can reuse, extend or modify the attributes and behaviors which is defined in other class.
In C#, the class which inherits the members of another class is called derived class and the class whose members are inherited is called base class. The derived class is the specialized class for the base class.

A class is a user-defined blueprint or prototype from which objects are created. Basically, a class combines the fields and methods(member function which defines actions) into a single unit. In C#, classes support polymorphism, inheritance and also provide the concept of derived classes and base classes.

An abstract class is an incomplete class or special class we can't be instantiated. The purpose of an abstract class is to provide a blueprint for derived classes and set some rules what the derived classes must implement when they inherit an abstract class. We can use an abstract class as a base class and all derived classes must implement abstract definitions. An abstract method must be implemented in all non-abstract classes using the override keyword. After overriding the abstract method is in the non-Abstract class. We can derive this class in another class and again we can override the same abstract method with it.

In c#, Destructor is a special method of a class, and it is used in a class to destroy the object or instances of classes. The destructor in c# will invoke automatically whenever the class instances become unreachable.

Properties of destructor in c# programming language : 
In c#, destructors can be used only in classes, and a class can contain only one destructor.
The destructor in class can be represented by using the tilde (~) operator
The destructor in c# won’t accept any parameters and access modifiers.
The destructor will invoke automatically whenever an instance of a class is no longer needed.
The garbage collector automatically invokes the destructor whenever the class objects are no longer needed in the application

Interface in C# is a blueprint of a class. It is like abstract class because all the methods which are declared inside the interface are abstract methods. It cannot have method body and cannot be instantiated. It is used to achieve multiple inheritance which can't be achieved by class. It is used to achieve fully abstraction because it cannot have method body. Its implementation must be provided by class or struct. The class or struct which implements the interface, must provide the implementation of all the methods declared inside the interface.

Tip 1 : Be sure to do your homework on the organization and its culture before the interview.

Tip 2 : Employers want to understand how you use your time and energy to stay productive and efficient. Be sure to emphasize that you adhere to deadlines and take them seriously.
 

Tip 3 : Talk about a relevant incident that made you keen on the profession you are pursuing and follow up by discussing your education.
