I'm in a similar boat as you in all my other schools. Its been months, I was completed everywhere the first week of september, and i haven't heard anything. I know some schols have pre interview hold, but I'm not sure.
I can tell you that I got my invite from AECOM a month after applying.
Since we were done at the same time, I don't know what that means for you. It was like that for me post secondary at mayo and the length of time meant a rejection. But every school is different, and i've been hearing from people who, months later, finally get their interview invite. So while i wouldn't give up hope, I wouldn't dwell on it happening either. There's always giving them a call to ask, I don't know if they'll tell you anything, but you may feel better and they were always very honest with me when i called! Good luck
