Journey
I started my preparation when I was in my third year. Then, I took a competitive programming course from Coding Ninjas, which helped me a lot with my DSA concepts and especially with my logical thinking. After completing the course, I began practicing coding on different coding platforms.
Application story
It was an off-campus drive, and it was a walk-in interview. There were three rounds, including the Technical interview round and the HR interview round. The first round was an aptitude test, with a duration of around 15 minutes. It was scheduled on 6th September at 11 AM. After being shortlisted, I received a message from HR for the first interview.
Why selected/rejected for the role?
I got an offer from Centilytics because I was able to answer all the questions properly. I briefly explained all my projects.

The interview was scheduled for 6th September 2023, and the duration of the interview was around 30 minutes. The first question he asked me was, "Tell me about yourself." Then, he asked me about my project and focused on my knowledge of the project. After that, he asked me to tell him something about myself that was not mentioned in my resume. He also asked me about my non-technical skills, my weaknesses, and my achievements.

Question:
Find the Second Largest Element in an Array
Write a program to find the second largest element in a given array of integers.
For example, in the array [3, 5, 7, 2, 8], the second largest number is 7.
The program should handle edge cases such as:
Arrays with duplicate values (e.g., [3, 3, 5, 5, 7] should return 5).
Arrays with fewer than two distinct elements (e.g., [5] should output an error or a specific message).
Problem approach
To achieve an O(n) time complexity without sorting, we can traverse the array once while maintaining two variables:
First Largest (first): To keep track of the largest distinct element found so far.
Second Largest (second): To keep track of the second largest distinct element.

Find All Pairs with a Given Sum
Write a program to find all unique pairs of integers in an array whose sum equals a given target value.
A list of unique pairs of integers that add up to the target sum.
For example:
Input: array = [2, 7, 4, -5, 11, 5, 20], target = 9
Output: [(2, 7), (4, 5)]
Problem approach
Use a set to store numbers you’ve already seen.
Use another set to store pairs to avoid duplicates.
