Buffalo Exchange Buyer - Solo interview questions

It was my first time attempting to sell some clothes with my sister when I was approached by a staff member whom I would later learn was the Assistant Store Manager. He asked if I was interested in apply to be a buyer, which I was. A paper application form was provided for me to fill out after which he said he wanted to hold a spot interview at that time. He asked some simple interview questions then presented a bag of clothes to conduct a "mock buy". I totally butchered the buying test as I knew close to nothing about brands, trends, or resale. Based on his condescending response and our ensuing impersonal work relationship, I believe if I had not followed up with an online application for the position, I would have never received my call back. Thanks to his lack of documentation, the store manager reached out for a first interview, to which I feigned ignorance and the store manager apologetically held a "2nd" interview. Felt better about it and turns out so did she. Was called back for a third interview which was virtually a formal job offer meeting.
