I applied in-person. The process took 5 days. I interviewed at ALDI (Brandywine, MD) in Mar 2011
Interview
I went to an open hiring event at a hotel, where I was able to fill out an application and meet directly with the hiring district manager, who simply asked availability. Two hours later, I received a phone call from the same DM and scheduled an interview a week later. When I arrived at the interview, I was not only interviewed by that DM, but also the regional manager as well. They were thorough and upfront about the brand, what to expect, and the benefits of working at Aldi.
The process took 1 day. I interviewed at ALDI (Roswell, GA) in Apr 2012
Interview
This company is always hosting hiring events and I'm sure 100's of people show up and apply. The thing is they only have maybe 2 positions to fill(they don't tell you that). You read the job description, fill out an application, and they ask a few ?'s.
