I also got the call today for the -400 class. I was a September interview as well (15th I believe). I can't wait to start. It took about two seconds after I hung up to fire off my two weeks notice! Thank you to everyone on here for keeping us all updated. I feel like you've really taken care of us along the way and hopefully I can pay it forward to the next class of Atlas hopefuls! For everyone that got the call for the 23rd I'll see you by the grill for adult beverages!!
