Interview process had one phone screen. The interviewer from customer promise team asked this question. When i provided the entire answer in 0(n), interviewer was not Ok with the answer because interviewer was not able to understand the simple for loop i have written. I had to iterate through the for loop to explain him the result after every iteration; and still was 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 ever seen such an interviewer. I don't understand why these so called engineers in such companies ask questions when they cannot even understand. His language was awful. I wish i had not even attended the technical phone screen. I hope this review helps for someone applying for Customer promise team in Walmart. I also hope HR from walmart looks at this review and does something to change the interview process. Perhaps, they should have manager or someone else to shoulder the interviewer.
