Walmart Labs Interview Experience (For Internship)
It was an online round of 1 hour hosted on Hackerearth. It consisted of 25 MCQs related to core cs topics & aptitude (around 4-5 questions) and 1 coding question. The coding question goes like this :
Find the length of the smallest substring in a given string having the maximum number of distinct characters.
1<=|s|<=100000, |s| = length of string
16 students got shortlisted for f2f interview.
It was an HR round and it went for about half an hour. The interviewer started with the standard “Tell me about yourself” and then asked me about my family background and some other HR questions.
He asked me how I developed an interest in programming in spite of being a Mechanical Engineer and I think that I was able to convince him (Be prepared of such questions if you are from non -circuit branches). He also asked my approach for the coding question that was asked in the online test. I told him I used binary search to solve it in O(NlogN) and he liked my approach.
Finally, he asked me for my Codeforces rating and the round ended with “Why should I hire you”.
5 out of 16 students got selected, I being one of them 🙂
