In this day and age of problem employees, companies try to do better background checks than they used to. Some can get back to you in a day or two. It just depends how desperate they are to fill the position or if they have several good choices from which to choose.
Speaking of Borders, I worked for their Waldenbooks division at a local store from 1988 to 1990. Back then, Waldenbooks was a division of KMart. That store closed back in February, while their downtown store converted into a Borders about a year or so ago. I loved working there because I could get my Star trek books at a great employee discount. You might be able to do the same with CSI books. And if the store is in a mall, you might be able to get discounts at some of the food court booths.
