Based off of my particular experience, they really just go strictly off of what you put on the application center. There's really no need to check up on it, because there's generally only one person that scopes out people to hire (usually being the manager of the particular departments you apply for), and if you try and check up on an application there's a good chance you won't be able to talk to that particular department manager, either them being busy or not being scheduled, plus they have a lot of others to look through, so it will do nothing. If they want you, they'll call you and tell you what location it is and what time to come in for an "interview" if you are still interested. After I applied, a couple of weeks later the customer service manager called me she did just this. I came in, waited for a couple of minutes, and she brought me over to a small office. She was nice, friendly, and got along with everyone, so I felt comfortable around her despite being the awkward person that I am. We sat down in said office, and she looked through a file with my application in it and was asking me about myself in regards to what was on my application and whatnot (where my last residence was, my future plans, where I was going to college, etc.), and just some basic stuff, as well as taken an under the tongue drug test she would have to send off. After basically just a conversation, she told me when I'd have my training and when she planned on having me start officially, as well as how much my starting pay would be. She took me over to the next office over and gave me a few sheets to sign and a couple of papers in regards to my training. Overall pretty laid back and didn't feel like an interview in a traditional sense.
