The entire process was slow, confusing and non-responsive. Received online assessment 5 months after applying and went through the first round of interview. No response after that and recruiter was non-responsive.

Question 1
online assessment and then 24-hour take-home data challenge
I applied online. I interviewed at Walmart in Apr 2022
Interview
The first round was a technical assessment task. There were some basic SQL questions, and a coding exercise on Time Series forecasting. I had never used time series forecasting before, so I could not finish that exercise.
I applied through college or university. The process took 2 weeks. I interviewed at Walmart (Pittsburgh, PA) in May 2022
Interview
The experience was good overall. The people were very professional and were prompt too. The interviers were polite and professional. The questions seemed moderately difficult in retrospect. Although the job title said data science, they asked me a lot of coding questions which are typically asked for software development engineer roles.
