Got this letter this morning
"Based on your response, we have reserved a place for you to attend the ATCS Pre-Employment Processing Center (PEPC) which will be held in Memphis, TN July 21-25."
I was then given the option to choose between monday the 21st or tuesday the 22, since I was selected for enroute. (terminal will be on wednesday & thursday) I chose Monday so I don't have to take off an extra day at work. I'm waiting to get that final confirmation e-mail.
