My store easily gets 4-5 new applications every day. Which totals out to well over 150 applications a month. How many people have we hired in the last month? 1. The most annoying thing are these fucking kids that come in wearing street clothes, mutter something along the lines of "Ya'll hirin'?" And then ask for an application. Oh, and then they ask for a pen because even though they knew they were going to go around filling out applications they couldn't be bothered to bring their own pen. Half of them get thrown in the dumpster immediately because they are in school and can't work anything other than evenings (and refuse to work weekends).
I imagine Willco has some pretty good stories about his least qualified applicants

But anyhow, just figuring the odds (1 new hire for every 150 applications in my line of work), you are not in good shape. The best thing to do is meet the store manager, dress nicely, make an impression, be articulate and thoughtful. Turn in your app and find out when a good time would be to call in and check up. Oh, and don't piss off the peons in the store with annoying requests for water or pens or whatever -- they may not chuck your app into the garbage, but they can easily tank it by writing something nasty about you on a sticky note and attaching it to your app.
Most major companies put online PDFs of applications on their website. Download these and use a program like FoxIt to type your application. Not only does that immediately set you apart from the hundreds of applications with pathetic handwritten chicken scratches, but you can use that one single application (or a variation of it) to apply to every single store in your area. So instead of filling out 10 different applications for 10 different Gamestop stores, you can type out 1 app and give it to all the Gamestops.
