Walmart Merchandise Associate interview questions

A worker called for me as I was waiting outside the staff room door, and led me to a break room. They then told me to write my availability and proceeded to ask a few questions.

They were very rushed and late to my interview and asked short questions. Didn't seem like an interview, wasn't even in a proper office. Quickly asked 3 questions and said I could leave, felt very overdressed and out of place compared to others.
