Interview preparation journey
Journey
My journey in Java started from scratch, driven by curiosity to understand how programs work. Initially, even basic concepts like variables, loops, and classes seemed challenging, and I often struggled to connect theory with practical application. However, I chose to focus on building a strong foundation rather than rushing into advanced topics.
Application story
I applied for this role through an online job portal after finding a position that matched my Java and backend development skills. After submitting my application, I was contacted by the recruitment team with clear instructions about the next steps. The entire process, from application submission to interview scheduling, was smooth and well organized, with timely communication at each stage. The experience was professional and gave me confidence to prepare effectively for the interview.
Why selected/rejected for the role?
I was rejected for the role due to budget constraints, but the interview process was smooth, and the questions were not very high-level.

1. Pair Sum
Easy

0/40
Asked in companies
You are given an integer array 'ARR' of size 'N' and an integer 'S'. Your task is to return the list of all pairs of elements such that each sum of elements of each pair equals 'S'.
Note:
Each pair should be sorted i.e the first value should be less than or equals to the second value.
Return the list of pairs sorted in non-decreasing order of their first value. In case if two pairs have the same first value, the pair with a smaller second value should come first.
Problem approach
- Use a HashMap to store elements and their counts.
- Traverse the array and for each element x, check if target - x exists in the map.
- If it exists, store the pair and reduce the count to avoid duplicates.
- Return all valid pairs.
2. Reverse the String

Asked in companies
You are given a string 'STR'. The string contains [a-z] [A-Z] [0-9] [special characters]. You have to find the reverse of the string.
For example:
If the given string is: STR = "abcde". You have to print the string "edcba".
follow up:
Try to solve the problem in O(1) space complexity.
Problem approach
- Convert the string to a character array.
- Swap characters from start and end moving towards the middle.
- Convert the array back to a string.
