I applied via Campus Placement and was interviewed in Sep 2024. There were 5 interview rounds.
Round 1 was aptitude round, it consisted of java and c++ snippets and we had to guess the output. Apart from that there were problems on speed, velocity, distance and time. Problems on word-letter patterns were also asked. The aptitude round had 30 questions and time given was 30 minutes.
Aptitude round was the only elimination round. The next following 4 rounds were non-elimination rounds. Coding test included 3 questions - 1 and half hour was given to solve the same. It is fine if you don't perform well here, since it is a non-elimination round. But try to solve 1 and half or 2 questions atleast. The questions were mainly based on 1d arrays, 2D arrays, strings and string arrays.

Access modifiers in Java control the visibility of classes, methods, and variables.
There are four types of access modifiers in Java: public, private, protected, and default.
Public: accessible from any other class.
Private: only accessible within the same class.
Protected: accessible within the same package and subclasses.
Default: accessible only within the same package.
Example: public class MyClass { private int myVar; p
Encapsulation, Inheritance, Polymorphism, Abstraction
Encapsulation: Data hiding and bundling of data with methods. Example: Using private variables and public methods.
Inheritance: Reusing code and creating a hierarchy of classes. Example: Subclass inheriting properties and methods from a superclass.
Polymorphism: Ability to present the same interface for different data types. Example: Method overloading and overriding.
