Best Buy interview questions

It was a phone interview with general questions and then a invitation to a 1:1 interview at the store. This interview was with some department supervisor I think. The store was at the Yorkdale mall and the interview was in a small room, I think the surveillance room. The questions were mainly general questions, why, how, the usb question (how many usb can be attached to a computer) and the irq question (irq for serial devices). Didn't get a call afterwards.
