Selected Interview preparation journey
Journey
I started my preparation by focusing on strengthening my fundamentals in programming, Data Structures, and core subjects like OOPS and DBMS, as I realized that clarity in basics is the foundation for cracking interviews.
Initially, problem-solving felt challenging, but with consistent practice and regular revision, I gradually improved my logical thinking and coding confidence. Alongside technical preparation, I worked on improving my communication skills and participated in mock interviews to overcome nervousness.
There were a few setbacks during the placement season, but I treated them as learning experiences and kept refining my approach. With persistence, discipline, and confidence in my preparation, I was able to successfully crack the interview and secure the role.
Application story
I applied for the Associate Professional role at DXC Technology through my college’s on-campus placement drive after attending the Pre-Placement Talk. The eligibility criteria and job description were clearly explained beforehand, which helped me understand the expectations. After applying, I appeared for the online assessment, and shortlisted candidates were then invited for the interview round conducted over the next few working days. The entire process was smooth and well-structured, with timely communication from the placement cell and the company regarding each stage of shortlisting and interview scheduling.
Why selected/rejected for the role?
I believe I was selected for this role because I demonstrated strong clarity in fundamentals, a structured problem-solving approach, and good communication skills during the interview process. I focused on explaining my thought process clearly rather than rushing to answers, which reflected my conceptual understanding and logical thinking. Additionally, I showed a positive attitude, willingness to learn, and flexibility regarding roles and locations, which aligned well with the company’s expectations for an Associate Professional. Overall, consistent preparation, confidence, and the ability to stay calm under pressure played a key role in my selection.

2. Operating System
Problem approach
Remember Coffman conditions – Mutual Exclusion, Hold & Wait, No Preemption, Circular Wait.
Practice basic scheduling numericals and formula for waiting time.
4. Check If The String Is A Palindrome
Easy

0/40
Asked in companies
You are given a string 'S'. Your task is to check whether the string is palindrome or not. For checking palindrome, consider alphabets and numbers only and ignore the symbols and whitespaces.
Note :
String 'S' is NOT case sensitive.
Example :
Let S = “c1 O$d@eeD o1c”.
If we ignore the special characters, whitespaces and convert all uppercase letters to lowercase, we get S = “c1odeedo1c”, which is a palindrome. Hence, the given string is also a palindrome.
Problem approach
Use two-pointer approach or reverse string and compare. Time complexity O(n).
5. Second Largest Number
Easy

Asked in companies
You have been given an array ‘a’ of ‘n’ unique non-negative integers.
Find the second largest and second smallest element from the array.
Return the two elements (second largest and second smallest) as another array of size 2.
Example :
Input: ‘n’ = 5, ‘a’ = [1, 2, 3, 4, 5]
Output: [4, 2]
The second largest element after 5 is 4, and the second smallest element after 1 is 2.
Problem approach
Traverse array once while maintaining two variables (largest and second largest). Time complexity O(n).

Coding problem3
Timing: Conducted during normal working hours via scheduled video call (not late night).
Environment: Professional and smooth; the interviewer ensured proper connectivity and made the candidate comfortable before starting.
Significant Activity: Focused on problem-solving approach; asked to explain logic clearly and discuss time & space complexity. Some follow-up questions were based on the optimized approach.
Interviewer: Friendly, patient, and interactive; gave hints when required and mainly evaluated conceptual clarity and structured thinking rather than just the final answer.
1. Operating System
Difference between process and thread. (Learn)
Problem approach
Focus on memory sharing, overhead, and execution context.
2. Day 8 : Second largest element in the array
Easy

0/40
Asked in companies
You have been given an array/list 'ARR' of integers. Your task is to find the second largest element present in the 'ARR'.
Note:
a) Duplicate elements may be present.
b) If no such element is present return -1.
Example:
Input: Given a sequence of five numbers 2, 4, 5, 6, 8.
Output: 6
Explanation:
In the given sequence of numbers, number 8 is the largest element, followed by number 6 which is the second-largest element. Hence we return number 6 which is the second-largest element in the sequence.
Problem approach
Traverse the array once while maintaining two variables (largest and second largest). Update them accordingly without sorting.
Time Complexity: O(N)
Space Complexity: O(1)
3. Majority element
Easy

Asked in companies
You have been given an array/list 'ARR' consisting of 'N' integers. Your task is to find the majority element in the array. If there is no majority element present, print -1.
Note:
A majority element is an element that occurs more than floor('N' / 2) times in the array.
Problem approach
Use Moore’s Voting Algorithm to find the candidate in O(N) time and O(1) space, then verify if it appears more than N/2 times.
