Boots Sales Associate interview questions

Applied online via the Boots website. They emailed with an assessment which I had to complete. After that, I received an email to arrange a time for an interview. Interview would have been okay if it weren't for that fact that I was unable to fulfill their requirements with regards to specific shifts (which were not stated on the website when applying).

Promised an hour long interview, they smiled at me for 15 minutes and cluelessly asked me for my information. I didn't get any chance to demonstrate myself on the sales floor (the store was fairly busy) and they were so disorganised and didn't realise the vacancy was for their store at all
