I applied online. The process took 2 weeks. I interviewed at Walmart (Sunnyvale, CA) in Feb 2016
Interview
3 people took my interview. I felt that the interviewers didn't really ask relevant questions. 1st guy asked me questions about my past experience but found it difficult to understand what I was trying to explain. May be he was not interested and was astonished when I said that as a part of a feature we executed Groovy scripts from Java classes and the scripts were stored in database. To that his question was did you store serialized objects in db. He had a difficult time understanding that classes were compiled at runtime. BTW I wrote a recursive function that would give valid palindromes in a string and made it work for the test string.
2nd person probably worked mostly on binary data. His 1st question was on count set bits in a 32 bit integer. I admitted to him that I did not deal with binary data on daily basis and the last time i used bitwise operator was in school 10 years back. However, gave him an array based solutions where a I counted number of set bits but wasnt enough. Another question again on binary stream of data which again i converted to a string example and explained my approach. While explaining the apprach i started with general case ignoring all corner cases to which the interviewer said why are you not writing entire function. Then when I started writing entire function he said I spend way to much time in writing corner cases. REALLY?? Then he asked me a question about traversing all nodes of a graph. To which i gave him recursive solution with neighbors. He didnt understand the following java for loop
for(Node n : nodeList) and he said why was i writing pseudo code. I explained that it was valid syntax but he didnt believe. I believe he was from a world where everything was binary and didnt deal with Java on daily basis and I was form a world that used JAVA and non binary data on daily basis.
Honestly try to connect with the background of the person and ask questions relevant to your job. Testing algorithmic acumen of someone is one thing and but atleast make sure that you are asking the right question.
Interview questions [4]
Question 1
Give me all the permutations of valid palindrome in a string?
I strongly believe this is highly flawed question at least from example expected output. I hope some one can prove me wrong.
it is a combination of 3 different problems
1. get all possible subsets of a string
2. check those subsets for possibility of a palindrome
3. get permutations of valid palindromes
I highly doubt that this can be solved in a span of 45 minutes.
Given a buffer of binary data separate data into different buffers based on a separator. Also within valid data discard specific bits and concatenate bits.
Expect standard DSA questions focused on Maps and Trees, including traversal and optimization. There will likely be a system design interview to discuss architecture and scalability, followed by a Hiring Manager round covering experience, projects, and problem-solving approach.

I applied through university. I interviewed at Walmart (Delta, BC) in Jan 2026
Interview
5 step interview, I think it was way too much. They should not be stressing applicants like this. They should let you dictate what operating procedures you can demo without rancomly giving it to you on the spot.

Many questions about GraphQL and node.js for internal applications.

Interview
The process was a Karat interview, technical video interview, and then the onsite. I was asked many questions about Java Springboot, but the position I applied did not mention anything about Java.
