ALDI Part Time Cashier interview questions

The interview didn't start until until 20 minutes after it was scheduled. The interview started with me verifying my personal information, then I was asked what my availability was. I was looking for a part time job and I implied that in my job application so I confirmed I was able to work anytime after 5 pm. I was then told that all "part-time" employees started at 2 and if I couldn't work at that scheduled time then I should just leave "and stop wasting everyone's time". The application specifically had available times on it (i.e. 5 am - 2 pm, 5 pm - 11 pm) so I don't understand why that wasn't checked before I was called in for an interview. I also think the application should be changed to accurately express their wishes.
