ALDI Store Assistant interview questions

Filled in an online application form which was pretty standard but rather lengthy. Received email inviting me to a group assessment and was asked to pick a time. Group assessment involved 13 of us all 'interviewing' at once. Everyone gave a brief introduction; name, age, previous employment etc etc. Filled out a registration sheet. What do you know about Aldi? Basic maths test. Group discussion putting 6 tasks into order of priority with one person then reading out the groups decision. Any questions? All 13 of us were finished in just over 35 minutes. Then an automated rejection less than 24 hours later. I'm just going to chalk this one up as my job searching rock bottom, I'm not even classing it as an interview. The whole process made me feel very disposable and worthless which I get that you are as a jobseeker, but you sort of want them to pretend that you aren't. The whole thing felt very Aldi in that it was a 'stack them high sell them low' type operation, discount interviewing at it's efficient best.
