Interview preparation journey
Journey
During my second year, I started my coding journey with inconsistent dedication. It wasn’t until the middle of my third year that I fully committed to it. I made a conscious decision to practice coding regularly, solving at least 8 to 9 coding problems every day on popular coding platforms.
Application story
I first learned about the company during a campus visit arranged through my college's Training and Placement Office (TPO) job portal. Curious to explore the opportunity, I quickly filled out the application and was excited to be shortlisted for the initial online coding round. The questions in the test were fairly simple, and I was able to solve them without much trouble. As a result, I progressed to the face-to-face technical interview, which also went smoothly. However, despite the positive experience, I was disappointed to learn that I was not selected for the final round and was ultimately rejected for the role.
Why selected/rejected for the role?
I was rejected during the hiring process because I was unable to provide an optimized solution for one of the questions asked in the interview. Despite my best efforts, I struggled to come up with an efficient and effective approach to solve the problem, which ultimately resulted in my not being selected for the position.

1. Bursting Balloons

Asked in companies
You are given an array 'ARR' of N integers. Each integer represents the height of a balloon. So, there are N balloons lined up.
Your aim is to destroy all these balloons. Now, a balloon can only be destroyed if the player shoots its head. So, to do the needful, he/ she shoots an arrow from the left to the right side of the platform, from an arbitrary height he/she chooses. The arrow moves from left to right, at a chosen height ARR[i] until it finds a balloon. The moment when an arrow touches a balloon, the balloon gets destroyed and disappears and the arrow continues its way from left to right at a height decreased by 1. Therefore, if the arrow was moving at height ARR[i], after destroying the balloon it travels at height ARR[i]-1. The player wins this game if he destroys all the balloons in minimum arrows.
You have to return the minimum arrows required to complete the task.

Clarify the requirements and constraints of the system design problem. Identify the key components and modules required for the solution. Consider scalability and performance factors. Design a suitable data storage and database solution. Define the system architecture, carefully evaluating trade-offs and limitations.

Asked in companies
You have been given a Singly Linked List of integers, determine if it forms a cycle or not. If there is a cycle, remove the cycle and return the list.
A cycle occurs when a node's ‘next’ points back to a previous node in the list.
