The process was quite straightforward! I obtained this opportunity by sending cold emails. I received a Google Meet link for the interview. The interviewer asked me to introduce myself, which I did, and then he began with some basic data structure and algorithm (DSA) questions, such as "What is a data structure?" and "What are the types of data structures?" He then asked me to explain the types in detail. After that, he requested me to open an online compiler and write code to implement a linked list, which I completed. The interview concluded with him asking about my college, and that was the end of our conversation. Later, I received notification from HR that I was selected.

Q4. What is Linked List?
Ans. 
A linked list is a data structure where each element is connected to the next element through pointers.
