Parts Store Rant, the other side of the story
I believe part of the reason they ask so many questions is so as they are entering the information into the computer, it is tracking the exact vehicles they are selling parts for so they know what to stock.
That being said, my local AutoZone sucks. I tried about ten years ago to get a part time job there. I had worked as a parts/service writer/tire salesman at two different jobs for a few years, and had also been a GM dealership tech. I knew catalogs and computers. I turned in my application and took the computer based automotive quiz to see if I knew enough abut cars or not. The lady said it would take 45 minutes. Well, it didn't. It took about five it was so easy. They kept the hiring sign up and never hired me...
I figured I knew too much. This was the store tht ALWAYS gave me the wrong parts, and I was one of those guys who happened to know what it was I was working on.
To the o.p., don't get too bent out of shape, I'm sure your one of the good guys behind the counter. It's the other people that should be working flipping burgers that give you a bad rap.
