The four pillars of OOP are encapsulation, inheritance, polymorphism, and abstraction.
Encapsulation: Bundling data and methods that operate on the data into a single unit. Example: Class in Java.
Inheritance: Ability of a class to inherit properties and behavior from another class. Example: Subclass extending a superclass.
Polymorphism: Ability to present the same interface for different data types. Example: Method ...
Classes are blueprints for creating objects in object-oriented programming. Objects are instances of classes with their own unique attributes and behaviors.
Classes define the properties and behaviors that objects of that class will have.
Objects are instances of classes that can store data and perform actions.
Classes can inherit properties and behaviors from other classes through inheritance.
Objects can interact wi...

A palindrome is a word, phrase, number, or other sequence of characters that reads the same forward and backward.
Check if the given string is equal to its reverse to determine if it is a palindrome.
Ignore spaces, punctuation, and capitalization when checking for palindromes.
Examples: 'racecar', 'A man, a plan, a canal, Panama!'
OOP concepts like Abstraction, Polymorphism, and Inheritance are fundamental principles in object-oriented programming.
Abstraction: Hides complex implementation details and only shows the necessary features. Example: Car class with start() and stop() methods.
Polymorphism: Allows objects of different classes to be treated as objects of a common superclass. Example: Animal superclass with Dog and Cat subclasses.

Exception handling in Java is a mechanism to handle runtime errors and prevent program termination.
Types of exceptions in Java include checked exceptions, unchecked exceptions, and errors.
Checked exceptions are checked at compile time and must be handled by the programmer.
Unchecked exceptions are not checked at compile time and can be handled using try-catch blocks.
Errors are serious issues that cannot be handled ...
Static in Java is a keyword used to create variables and methods that belong to the class itself, rather than instances of the class.
Static variables are shared among all instances of a class.
Static methods can be called without creating an instance of the class.
Static blocks are used to initialize static variables.
Example: public static int count = 0;
Inheritance in Java allows a class to inherit properties and behaviors from another class.
Inheritance allows for code reusability and promotes a hierarchical relationship between classes.
Subclasses can access the methods and fields of their superclass.
Java supports single and multiple inheritance through classes and interfaces respectively.
Oops concepts in Python refer to Object-Oriented Programming principles like Inheritance, Encapsulation, Polymorphism, and Abstraction.
Python supports Object-Oriented Programming (OOP) concepts like classes and objects.
Inheritance allows a class to inherit attributes and methods from another class.
Encapsulation restricts access to certain components of an object.
Polymorphism allows objects to be treated as instanc...
Release management is the process of managing, planning, scheduling, and controlling software releases.
It involves coordinating the release of software updates or new features to ensure a smooth deployment.
Release management includes tasks such as version control, testing, deployment, and communication with stakeholders.
It aims to minimize risks and disruptions during the release process.
Examples of release manage...
I appeared for an interview in Jan 2025.
The exam consists of seven sections, and the cutoff score is quite high; it is essential to complete the exam thoroughly.

Assisted in setting up and configuring network devices such as routers and switches
Troubleshooted network issues and implemented solutions
Collaborated with team members on various IT projects
Participated in meetings with clients to discuss project requirements
I have worked on various major projects including designing and implementing network infrastructure, developing automation scripts, and optimizing system performance.

Developed automation scripts to streamline system monitoring and maintenance tasks, saving time and reducing errors
Optimized system performanc...
The latest news I heard regarding technology is the release of the new iPhone 13 with improved camera features.
Apple recently announced the release of the iPhone 13 series with upgraded camera capabilities.
The new iPhone 13 models come with improved low-light performance and cinematic mode for videos.
Apple also introduced the A15 Bionic chip for enhanced performance and battery life.
I appeared for an interview in Feb 2025.
Sorting algorithms arrange data in a specific order, crucial for efficient data processing and retrieval.
Types of sorting algorithms include: Bubble Sort, Quick Sort, Merge Sort, and Heap Sort.
Bubble Sort is simple but inefficient for large datasets; it repeatedly steps through the list.
Quick Sort is efficient for large datasets, using a divide-and-conquer approach to sort elements.
Merge Sort divides the array into hal...
The Software Development Lifecycle (SDLC) is a structured process for developing software applications through various stages.
1. Requirements Gathering: Identify user needs and system requirements.
2. Design: Create architecture and design specifications for the software.
3. Implementation: Write and compile the code based on design documents.
4. Testing: Validate the software through various testing methods (e.g., unit t...
I applied via Campus Placement and was interviewed in Dec 2024. There were 2 interview rounds.
Aptitude test consists of topics like percentages ,profits and loss like this they covered all the topics there is verbal ability also
I appeared for an interview before Jul 2024, where I was asked the following questions.
Global variables are accessible throughout the program, while local variables are confined to the block or function where they are defined.
Global variables are declared outside of functions and can be accessed anywhere in the code.
Local variables are declared within a function or block and can only be accessed within that scope.
Example of a global variable: `int globalVar = 10;`
Example of a local variable: `void functi...
A for loop iterates through an array to print each element sequentially.
Use a for loop syntax: for (initialization; condition; increment) { }
Example: for (int i = 0; i < array.length; i++) { System.out.println(array[i]); }
In JavaScript: for (let i = 0; i < array.length; i++) { console.log(array[i]); }
In Python: for element in array: print(element)
A class is a blueprint for creating objects, while a method is a function defined within a class that operates on its data.
A class encapsulates data and behavior in object-oriented programming.
Example: class Car { } defines a Car class.
A method is a function that belongs to a class.
Example: class Car { void drive() { } } defines a drive method.
I applied via Campus Placement and was interviewed in Oct 2024. There were 3 interview rounds.
Covers all aptitude topics
I applied via Campus Placement and was interviewed in Sep 2024. There were 2 interview rounds.

I appeared for an interview in May 2025, where I was asked the following questions.
OOP is a programming paradigm based on objects, encapsulating data and behavior for modular and reusable code.
Encapsulation: Bundling data and methods that operate on the data within one unit (e.g., a class).
Inheritance: Mechanism to create a new class from an existing class, inheriting attributes and methods (e.g., a 'Dog' class inheriting from an 'Animal' class).
Polymorphism: Ability to present the same interface for...
Encapsulation is a fundamental concept in OOP that restricts direct access to an object's data and methods.
Encapsulation combines data and methods that operate on that data into a single unit called a class.
It restricts access to certain components, which is achieved using access modifiers like private, protected, and public.
For example, a class 'Car' can have private attributes like 'speed' and 'fuelLevel', and public...
