Lush Sales Assistant interview questions

So I did my interview at Clapham Junction store, first of all we all waited outside then we entered and they asked our name what contract we want and then made us wait. The manager states she doesn’t know why she’s being so nice and waiting for anyone else to show up pass the interview time. Then further more, we got split into groups of 3 and taken to each task, one was to find a perfect perfume given to the scenario, next was to practice arm massaging and third was gifts to find the best gift for someone. My personal experience I got put with 2 people who was very loud and everytime I tried to speak in, I couldn’t get a word in. The team members were very much it was clear they knew what they wanted. I personally feel as though I did quite well however the task with the massaging - well what if you weren’t comfortable to have someone rubbing your arm? Feel like this stuff should be listed before you show up to an interview plus in my group I was the only one who dressed smart, was there not a dress code? At the end the manager said she would want people to do a trial shift on the weekend, I already stated I wouldn’t be able to do the weekend as my job I’m still in I had a shift with and I think personally that’s why I didn’t make it through. My feedback was : ask more questions to establish the needs of the customer. However it was scenario based so how can I ask more questions when it’s not a real situation? I’d say just be open minded going into this interview and be prepared to be there for 2 hours.
