It depends on whom they wish to fill the position. Many applicants will never get called back. That's just the reality. If you were asked to fill out the additional document, such as w-4 form...etc, odds are the HR may be interested in giving you a spot. The background check will take about 2 to 3 days to clear, until they contact you to schedule an interview or orientation. All I can say is, good luck to you. You're gonna need it. :-)
P.S. Don't get discouraged if you don't get a call, just resume the process and attend as many appointments as you possibly can. I've been there, done that.
