I applied through an employee referral. I interviewed at Walmart in Feb 2020
Interview
Questions were not so difficult as was the environment/atmosphere the panel created. All three men with very condescending and dismissive attitudes and seemed very unimpressed right off the bat. Also asked me why my GPA was low (3.2) and was not prepared for the hostility. Know DS/ML concepts well and don't rely on the interviewer to help or instill confidence in any way.
