# Walmart CodeHers 2025 – My Selection Journey
In Feb, I applied for the CodeHers 2025 Software Engineering Internship at Walmart Global Tech India through Unstop.
Level 1: MCQ Challenge – Computer Fundamentals
The first round was a fast-paced test—25 questions in 25 minutes—that assessed our understanding of: Data Structures,Operating Systems, DBMS, Computer Networks, OOPs
Level 2 – Coding Challenge
Shortlisted candidates from Round 1 moved on to a 90-minute coding round with 2 problem statements (medium to hard difficulty). I managed to fully solve one problem and partially solve the second one
After the coding round, shortlisted candidates received a verification mail asking for basic details and confirmation. A few days later, I received the interview mail, confirming my slot and details.
Technical Interview 1
The discussion began with questions from my resume.I was asked to solve two string-related problems:
- Maximum character frequency
- Reverse words in a string I discussed the logic, optimized the approach, and wrote clean code. Additional topics included: Time and space complexity
Technical Interview 2 I was asked a medium-level tree-based DSA question. The interviewer closely observed my thought process, approach to optimization, and how I handled edge cases. I began by explaining a brute-force solution, then gradually moved to a more optimal approach using recursion and clear logic. Once the approach was validated, the interviewer asked me to code it out and also dry run it with sample inputs to test its correctness..
Final Result – Selected! After a thorough evaluation process, I received the final selection email.
