ALDI Shift Manager interview questions

Attended a hiring event where I blew the competition out of the water for the position by preparing a resume, cover letter and dressing in a shirt and tie (The only one of 100 people in attendance to do so; highly recommend it). Received a phone call within a few days from the District Manager and scheduled a 1:1 interview with her. After some simple, behavioral questions, proceeded to interview with the store manager I was to work with (with more of the same, easy questions) before ultimately submitting a drug test and a background check. After the results came in, I had a panel interview with some DM's and the regional VP where I had a moderately difficult 35 min interview. After a few days, I received the offer and accepted.

Ad in local paper said to apply in person the following Friday from 3-8PM. I arrived at 3, was told to fill out an application, and get in line. This is a grocery store, it is busy Friday afternoons. There was a single line, there were 75-80 people in front of me, it went half way around the store, we were trying to stay out of the way of the customers. What was management thinking? Such an inconvenience to the customers, much less potential employees. I have worked in grocery for 20 years, after waiting in line for half an hour took my resume and application and left. What was management thinking?
