It was kind of difficult the coding part
They asked basic on going topic like impact of AI
Linear regression is used for predicting continuous values, while logistic regression is used for predicting binary outcomes.
Linear regression is used when the dependent variable is continuous and has a linear relationship with the independent variable.
Logistic regression is used when the dependent variable is binary or categorical and the relationship between the independent variables and the outcome is non-linear.
Lin...

I applied via LinkedIn and was interviewed in Apr 2024. There were 2 interview rounds.
They gave 3 codes in which we have to write atleast 2 of them.
It was basic aptitude and reasoning
Amcat shl test
was conducted , long process
I applied via Naukri.com and was interviewed in Mar 2023. There were 3 interview rounds.
It's ask Quantitative, verbal Ability,and logical Questions.. All question was easily to hard levels..
I applied via Job Fair and was interviewed before Feb 2023. There were 3 interview rounds.
This is a basic test where you will be asked to solve logical and reasoning questions. Pseudo codes and some basic programs.
Object-oriented programming is a programming paradigm that organizes code into objects that interact with each other.
Encourages modular and reusable code
Focuses on data and behavior encapsulation
Supports inheritance and polymorphism
Examples: Java, C++, Python
Encapsulation is the process of hiding internal details and providing a public interface for accessing and manipulating data.
Encapsulation is a fundamental principle of object-oriented programming.
It helps in achieving data abstraction and data hiding.
By encapsulating data and methods within a class, we can control access to them.
Encapsulation improves code maintainability and reusability.
Example: A class with private ...
Program to find prime number
A prime number is a number greater than 1 that has no positive divisors other than 1 and itself
To check if a number is prime, iterate from 2 to the square root of the number and check if it divides the number evenly
If the number is divisible by any number in the range, it is not prime
Optimization: Only iterate up to the square root of the number, as factors repeat after that
I applied via Company Website and was interviewed before Apr 2023. There were 2 interview rounds.
I applied via campus placement at Sri Ramakrishna Institute of Technology, Coimbatore and was interviewed before Apr 2023. There were 2 interview rounds.
Easy basis aptitude questions like train and work
C, Java, Python are the main language
I applied via campus placement at VIT Business School, Vellore and was interviewed in Mar 2023. There were 4 interview rounds.
Was moderate level and quite easy to solve
Coding questions were basic and easy to solve
Pointers are variables that store memory addresses. They are used to manipulate data structures and improve program efficiency.
Pointers allow for dynamic memory allocation
Pointers can be used to pass values by reference
Pointers can be used to create linked lists
Pointers can be used to access array elements
Example: int *ptr = # // stores address of num variable
Example: void swap(int *x, int *y) { int temp = *x; *x =...
Arrays are fixed in size and contiguous memory while linked lists are dynamic and non-contiguous.
Arrays have constant time access to elements while linked lists require traversal.
Arrays are better for random access while linked lists are better for insertion and deletion.
Arrays use less memory overhead than linked lists.
Example: Array of strings - ['apple', 'banana', 'orange']
Variables are containers that store data values. There are different types of variables in programming.
Variables are declared using keywords like var, let, const.
Variables can store different types of data such as numbers, strings, booleans, objects, arrays, etc.
Variables can be global or local depending on where they are declared.
Variables can be reassigned with new values.
Examples: var age = 25; let name = 'John'; co
