ALDI Manager Trainee interview questions

There was a heavily promoted “Hiring Event” for a new store opening close by. I polished my resume, researched the Company and showed up in a full business suit. A young man simply took a copy of my application and said he’d review it and call if there was interest. What is the point of having a “hiring event” if no one is actually going to speak to you?? Couldn’t I simply have submitted my resume on line??
