The online round had 2 coding questions and one question of a regular expression.

Q1. 
Find All Pairs Adding Up to Target
Given an array of integers ARR of length N and an integer Target, your task is to return all pairs of elements such that they add up to the Target.
Input:
The first line ...read more
Ans. 
Find all pairs of elements in an array that add up to a given target.
• Iterate through the array and for each element, check if the complement (target - current element) exists in a hash set.

• If the complement exists, add the pair to the result. If not, add the current element to the hash set.

• Handle cases where the same element is used twice in a pair (e.g., target = 6, array = [3, 3]).

First 10 minutes started with the Introduction. Then he asked about my projects. He seemed interested in my projects and asked a lot of questions about them. He asked questions related to Node Js, React Js, Mongo DB, AWS as all these were mentioned in my Resume. Around 25 minutes was completed explaining each and everything.

Then he started with the coding questions. I was allowed to share my screen and use any of my favourite text editors. I chose ‘VS Code’.

I was able to solve 2 coding questions very easily. I got stuck in the puzzle as I didn’t solve any puzzles before. I was able to come up with different approaches, but they weren’t the most optimal. He tried giving me a lot of hints but still wasn’t able to solve it. I had a positive can-do attitude throughout, and I was really close to solving it.

Feedback: He told me I performed well and asked if I had any questions for him. I asked for the solution to the puzzle. He explained to me the solution and I told him that I will practice puzzles.

Around 5-6 students got selected for 2nd Interview.

Q1. 
Move Zeros To Left
You are provided an array ARR of integers. Your task is to rearrange this array such that all elements with zero values are moved to the left, and all non-zero elements follow them, pre...read more
Ans. 
Rearrange array with zeros on the left and non-zeros on the right while maintaining original order.
• Iterate through the array from right to left, moving non-zero elements to the end of the array.

• Track the index where non-zero elements should be placed.

• Fill the beginning of the array with zeros and the rest with non-zero elements in their original order.

It started with a brief Introduction and in-depth discussions on projects. He also asked me a lot of questions about my previous internship. He asked me some behavioural questions as well.

I was able to solve the question, and he did not ask me any other questions. This round was really short for me and was finished in around 35 minutes, well before time. I asked about my feedback, and he told me that the ‘HR’ will get back to me. I thought he was not satisfied with my answers and I will be rejected though I gave very good answers to every question.

3 students got selected for the next round. I think he was satisfied and did not want to waste more time asking questions.
