I applied in May like many of you. I didn't want to take for granted that my app. carried over so I went to look and sure enough I needed to resubmit the application. All of my information carried over in the application data entry fields but I think what happens is the application is specific to each hiring window so you have to resubmit it for the new application window/job reference code. I am also waiting with baited breath for a phone call or email. I hope this info helps someone out there. Good luck everybody!
From what I understood, you don't. I wondered, too. So, I e-mailed a friend in the hiring dept. He told me that I would NOT have to fill out the app again, just keep updating my old app from May.
