Torchbox Junior Developer interview questions

They asked when I was available for interview over the following week. I responded and was met with radio silence. Several days after that week had passed they contacted me with a new date, which luckily I could do. The interview included many technical questions which I couldn't answer. For reference, I had no programming training or qualifications and was applying as a shift from physics. I made this clear on my application so why they asked all these things I don't know. At the end they said they'd let me know within a week. They never let me know either way. The whole thing felt like a bizarre waste of time.
