The interview experience was positive. I would rate it medium difficulty, with standard algorithm questions. As I was interviewing for a full-stack role, there were also some JavaScript UI questions. The process included one phone screen and six on-site interviews.

The lunch interview was strange. We got lunch from the food court to go and returned to the interview room. I never really got a chance to eat it because the interview started again immediately upon entering the room. I just managed a couple of bites when the interviewers switched.

After a week, the recruiter called me and said they wanted to move ahead. They asked about my current salary, etc. After I put forward my expected compensation, they told me they would get back to me, but they never did. After a few follow-up emails, I gave up. So, it seems what I have been reading on Glassdoor and Quora about Walmart Labs is true.

Overall, I felt the end negotiation was handled unprofessionally. I did not expect that from a big company like Walmart.
