OOP (Object-Oriented Programming) is a programming paradigm based on objects that encapsulate data and behavior.
Encapsulation: Bundling data and methods that operate on the data within one unit (e.g., a class).
Inheritance: Mechanism to create a new class based on an existing class, promoting code reuse (e.g., a 'Dog' class inheriting from an 'Animal' class).
Polymorphism: Ability to treat objects of different class...
This task involves counting the occurrences of each character and word in a given string.
Use a dictionary to store character frequencies. Example: 'hello' -> {'h': 1, 'e': 1, 'l': 2, 'o': 1}
For word frequency, split the string by spaces and use a dictionary. Example: 'hello world hello' -> {'hello': 2, 'world': 1}
Consider using Python's collections.Counter for a more concise solution.
Handle punctuation and c...
Calculate the sum of the diagonal elements in the upper or lower half of a matrix.
Identify the matrix size (n x n).
For upper half, sum elements where row index < column index.
For lower half, sum elements where row index > column index.
Example: For matrix [[1,2,3],[4,5,6],[7,8,9]], upper half sum = 2 + 3 + 6 = 11.
Example: For the same matrix, lower half sum = 4 + 7 + 8 + 9 = 28.
Calculate the sum of the diagonal elements in a square matrix.
A square matrix has equal number of rows and columns.
The main diagonal runs from the top-left to the bottom-right.
To find the sum, iterate through indices where row = column.
Example: For matrix [[1, 2], [3, 4]], sum = 1 + 4 = 5.
For a 3x3 matrix [[1, 2, 3], [4, 5, 6], [7, 8, 9]], sum = 1 + 5 + 9 = 15.
Reverse a string while counting the characters in each word, providing a clear output of the reversed string and character counts.
String Reversal: To reverse a string, iterate through it from the end to the beginning, appending each character to a new string.
Character Counting: Split the string into words, then count the characters in each word using a loop or built-in functions.
Example: For the input 'Hello World...
OOP is a programming paradigm based on objects, encapsulating data and behavior through key concepts like inheritance and polymorphism.
Encapsulation: Bundling data and methods that operate on the data within one unit (e.g., a class).
Inheritance: Mechanism to create a new class using properties and methods of an existing class (e.g., a 'Dog' class inheriting from an 'Animal' class).
Polymorphism: Ability to present ...
Data modelling is the process of creating a visual representation of data and its relationships within a system.
Identifying entities and their attributes
Defining relationships between entities
Creating a schema to represent the data
Normalization to reduce redundancy
Example: Entity-Relationship Diagram (ERD)
Annotation used in Java to inject dependencies
@Wire annotation is used in Java to inject dependencies
It is typically used in frameworks like Dagger or ButterKnife
Example: @Wire TextView textView;
Security model refers to the framework that defines how security is implemented in a system or application.
Security model determines who can access what resources and under what conditions
It includes authentication, authorization, encryption, and auditing
Examples of security models include discretionary access control (DAC), mandatory access control (MAC), and role-based access control (RBAC)
Clouds are visible masses of water droplets or ice crystals suspended in the atmosphere.
Clouds are classified based on their altitude, shape, and appearance.
Types of clouds include cirrus, cumulus, stratus, and nimbus.
High-level clouds are found at altitudes above 20,000 feet, while low-level clouds are below 6,500 feet.
Clouds can also be classified as convective, stratiform, or cumulonimbus.

I appeared for an interview in Feb 2025, where I was asked the following questions.
DSA stands for Data Structures and Algorithms; SOQL is Salesforce Object Query Language for querying Salesforce data.
DSA is essential for efficient problem-solving in programming.
Common data structures include arrays, linked lists, stacks, and queues.
Algorithms can be sorting (e.g., quicksort) or searching (e.g., binary search).
SOQL is similar to SQL but specifically designed for Salesforce data.
Example of SOQL: SELECT...

I applied via Recruitment Consulltant and was interviewed in Apr 2024. There was 1 interview round.
Campaigns, Promotions, and Coupons are marketing strategies used to attract customers and increase sales.
Campaigns are strategic marketing efforts to promote a product or service over a specific period of time.
Promotions are temporary incentives offered to customers to encourage purchases, such as discounts or free gifts.
Coupons are vouchers that entitle the holder to a discount on a particular product or service.

Global JS refers to JavaScript variables or functions that are accessible from anywhere in the code.
Global JS variables are declared outside of any function and can be accessed from any part of the code.
Global JS functions are defined without being enclosed within another function and can be called from anywhere in the code.
Using global variables or functions can lead to potential conflicts and security risks.

I applied via Campus Placement and was interviewed in Jan 2023. There were 4 interview rounds.
Aptitude round was not so tough, moderate level questions were there.
A program to find palindrome numbers in a given range.
Iterate through the given range of numbers
Convert each number to a string and check if it is equal to its reverse
If yes, add it to the list of palindrome numbers
Carry is generated when the sum of two digits is greater than 9.
Carry is a digit that is carried over to the next place value in the sum.
For example, in the sum 56 + 78, the carry generated is 1 (5+7=12, carry 1, 6+8+1=15).
Carry is important in addition of large numbers and in binary addition.
