I appeared for an interview before Jun 2024, where I was asked the following questions.

  • Q1. What is list,queue and set , how to implement them in simple coding without using them?
  • Ans. 

    Lists, queues, and sets are fundamental data structures used to store collections of items with different properties.

    • List: An ordered collection that allows duplicates. Example: [1, 2, 3, 2].

    • Queue: A collection that follows FIFO (First In, First Out) principle. Example: Enqueue 1, 2, 3; Dequeue gives 1.

    • Set: An unordered collection that does not allow duplicates. Example: {1, 2, 3}.

  • Q2. Method overloading and method Overriding diffrence?
  • Ans. 

    Method overloading allows multiple methods with the same name but different parameters; overriding replaces a method in a subclass.

    • Method Overloading: Same method name, different parameters (e.g., `add(int a, int b)` and `add(double a, double b)`)

    • Method Overriding: Same method name and parameters in subclass (e.g., `class Animal { void sound() { } } class Dog extends Animal { void sound() { } }`)

    • Overloading is resolved...

Can speak English, can’t deliver in interviews
I feel like I can't speak fluently during interviews. I do know english well and use it daily to communicate, but the moment I'm in an interview, I just get stuck. since it's not my first language, I struggle to express what I actually feel. I know the answer in my head, but I just can’t deliver it properly at that moment. Please guide me
