The interview process included one phone screen.

The interviewer from the Customer Promise team asked this question: When I provided the entire answer in O(n), the interviewer was not OK with it because they were not able to understand the simple for loop I had written.

I had to iterate through the for loop to explain the result after every iteration, and they still were not able to understand. It was pathetic to see the interviewer struggling to understand the code I wrote.

In my 9 years of experience, I have never encountered such an interviewer. I don't understand why these so-called engineers in such companies ask questions when they cannot even understand them.

Their language was awful. I wish I had not even attended the technical phone screen.

I hope this review helps someone applying for the Customer Promise team at Walmart. I also hope HR from Walmart looks at this review and does something to change the interview process. Perhaps they should have a manager or someone else to support the interviewer.
