Dataset is an in-memory representation of a database while DataReader is a forward-only, read-only stream of data.
Dataset is disconnected and can be modified while DataReader is connected and read-only
Dataset can hold multiple tables while DataReader can only hold one table at a time
Dataset is slower than DataReader for large amounts of data
Dataset can be used for data manipulation while DataReader is used for read-onl
An index is a data structure that improves the speed of data retrieval operations on a database table.
Indexes are used to quickly locate data without having to search every row in a database table.
Types of indexes include clustered, non-clustered, unique, and full-text indexes.
Clustered indexes determine the physical order of data in a table, while non-clustered indexes create a separate structure to store the index da...

I applied via Naukri.com and was interviewed in Mar 2023. There were 3 interview rounds.
Method overloading is when multiple methods in a class have the same name but different parameters.
Allows multiple methods with the same name but different parameters to be defined in a class
Parameters can differ in number, type, or order
Example: void print(int num) and void print(String text) are overloaded methods
Method overriding is a feature in object-oriented programming that allows a subclass to provide a specific implementation of a method that is already provided by its superclass.
Method overriding is done when a subclass provides a specific implementation for a method that is already defined in its superclass.
The method in the subclass must have the same name, return type, and parameters as the method in the superclass.

A singleton class is a class that can only have one instance created and provides a global point of access to that instance.
Singleton classes are often used for logging, caching, database connections, and thread pools.
They typically have a private constructor to prevent instantiation from outside the class.
The class itself usually provides a static method to access the single instance.
Oops Pillars are the four main concepts of Object-Oriented Programming: Inheritance, Encapsulation, Polymorphism, and Abstraction.
Inheritance: Allows a class to inherit properties and behavior from another class.
Encapsulation: Bundles data and methods into a single unit, protecting data from outside interference.
Polymorphism: Allows objects to be treated as instances of their parent class, enabling flexibility in code.

Dependency injection is a design pattern in which components are given their dependencies rather than creating them internally.
Allows for easier testing by mocking dependencies
Promotes loose coupling between components
Improves code reusability and maintainability
Examples: Constructor injection, Setter injection, Interface injection
I was interviewed in Mar 2024.

A pipeline is a series of interconnected steps or stages in a process, where output of one step is input to the next step.
Pipeline is commonly used in software development for continuous integration and continuous delivery processes.
Each step in the pipeline performs a specific task, such as building, testing, and deploying code.
Pipeline automation tools like Jenkins, GitLab CI/CD, and Azure DevOps help in managing and

Abstract classes can have implementation details while interfaces cannot.
Abstract classes can have method implementations while interfaces cannot.
A class can inherit only one abstract class but can implement multiple interfaces.
Abstract classes can have access modifiers on their members while interfaces cannot.
Interfaces are used to define a contract for classes to implement.
Abstract classes are used to provide a commo
