ALDI Customer Assistant interview questions

I am so upset I am thinking of never going to Aldi to shop ever again. The process was horrifyingly long. I applied with my cv and answered their questions to which I passed and then had to submit a video recording of myself answering questions so now they have recordings of me!! I turned up, waited for 10 minutes & then was told that I had been contacted on my phone to reschedule the interview. I called them out on it & then I was told I would have received an email to which I didn’t. I can’t believe they made me out to be unreliable. That was the first alarm bell. No call or email & when I returned for the 2nd booked interview having waited 25 minutes standing I never received an apology for cancelling and having turned up. So unprofessional, another alarm bell. During the interview I was told that the job was (with great emphasis) horrendously full of hard labour & repetitive lifting which put me off a lot so I asked what he meant by it. Obviously it’s groceries so the heaviest would be a sack of potatoes or a crate of melon balls so I don’t understand why he tried putting me off the job so much. It felt orchestrated that I wasn’t wanted. And then he pulls out a test which I had 5 minutes to complete, didn’t he read I passed gcse maths and got a couple uni degrees on my cv? Surely that shows dedication, commitment, willpower, drive & a bit of problem solving right there cus otherwise how else would I have got into uni? I got the right company didn’t I? I’m applying for customer assistant and not going as for Astronaut? The funny thing is I was told during my interview that if I’m successful I would have to spend 1.5 hours unpaid to see if I would be liked and only then would I get a job. I was also insulted and implied I hadn’t any common sense. I was made to feel I was never going to get the job. I was made to feel the decision not to hire me at first glance & I can’t help to think it’s cus of my ethnicity or someone was already picked. There were so many alarm bells but I chose to see through them only because I was told it’s a good place to work and I held onto that. I’m so glad I’m not there, it would have made me so depressed. Go online and read reviews, it’s true what some of them say, they’re ball busting people who work you to the bone & when you can’t give back they get rid of you & that is what I felt come from my interview. It is not a good environment to be in. Never have I ever felt I needed to post a review of an interview process. I’ve applied to many jobs some I’ve been employed from and some I’ve been rejected but never have I ever felt so humiliated and treated so badly in one. Awful.
