Debenhams Visual Assistant interview questions

Applied online, process took about a week then had an email to book in a telephone interview, woman on the phone was friendly but was asking me so many questions!! It was like a proper interview. She then said she would get back to me, within 2 days she did to tell me I got through to the instore interview. I went to the store and sat with another girl who was also interviewing their. Then 2 people came over to us in the cafe (a young man and woman) told us we would have to dress the mannequins according to a theme. They gave me surfing brand and told me to dress the mannequins for a day at the races... I had to get the mannequins down off of high blocks on my own, dress them on my own and then put them back up high. There was 3 mannequins. After we had done that they came and asked me to explain why I had chosen what I had and then took me through the back for a formal interview, they asked me very in depth questions and kept smerking because they thought I didn't know what the questions meant. I was not successful and after the interview didn't want to be either.
