Walmart Data Scientist interview questions

This was the most unprofessional interview I have ever had. A complete waste of time! I applied online. Received an automated email 3 wks later, asking me to click a link to schedule a 30 min phone interview. The interviewer greeted me when I picked up the phone, but when I politely asked "how are you doing today" as a greeting, she didn't even respond. Then she just started to read some very basic questions. Most of the questions asked how many years of experience I had with certain languages or packages. I tried to explain that my previous job used the package only some of the time, so it was hard for me to give an accurate number of years. I could have said 7 years but honestly I might not be as proficient as someone who used it every day for 4 years. The interviewer didn't care about what I said and stressed that she only needed a number so I had to give her a number. If she wouldn't listen to my explanations, what was point of having such an "interview" with a real person? Walmart could have made these questions part of the job application form in the first place. When she asked why I left my previous job, I said it was a security clearance issue. She didn't understand it. I tried to explain but from her response I didn't think she got it. It wasn't so surprising given her thick foreign accent. I am an immigrant myself, but I really think for HR positions Walmart should hire someone who at least understand American life. It was very frustrating to talk to an HR only to realize she didn't even know what you were talking about. The interviewer sounded emotionless and robotic throughout the entire call. All questions asked were very basic and all about my background. They really should have been part of the job application. Nothing warranted an interview with a real person. It was a complete waste of my time. I received an automated rejection letter a week later.
