I applied online. I interviewed at Walmart (Fayetteville, AR) in Mar 2021
Interview
Behavioral questions followed by technical questions and two coding assignments were given. I talked with different persons in different departments. The recruiters connected me to several positions and it was confusing for which position I am getting the interview. Overall, they were nice and friendly.

I applied through a recruiter. I interviewed at Walmart in Jan 2021
Interview
The interview started off on a good note, with all the basic ML questions which I answered .
The behavioral round was probably the most weird one!
The person started off by taking about my experience and then followed up with the most weird technical question, Yes one technical question and it appeared to me that they didn't really know anything about it but kept asking the same question over and over again and expected me to talk about the exact same thing they were thinking about.
When it was my turn to ask questions, the person's answers gave me the impression that it wasn't very well structured and I started loosing interest in the position. The rest of the interviews went well/okay.
No reply from the recruiting team, guess I was ghosted.
After this interview, I started
