Walmart Global Tech Data Scientist interview questions

Recruiter doesn’t call you at your so said availability . Calls you out of the blue, when you are at work and asks. “Why Walmart?” Basic ML and coding interview - Camera turned off, sleepy interviewer starts asking about metrics, “Why is ‘Linear’ regression a good classifier” and given the data how does ‘Linear’ regression do classification!!! Seriously the interviewer doesn’t know linear and logistic regression!!! I had high hopes on the Walmart standard, but proved to be worst. One coding question - medium level about arrays. Took sometime to solve it after being misguided by sleepy interviewer. Got no reply from the genius people, not expecting too.
