Lush Customer Assistant interview questions

I applied by sending in my cv and a cover letter. Then I was called for a group interview. My group might have had around 20 people and we were subsequently split into smaller groups. My group had 4 people in it. There were four tasks to be performed. Our first task was to demonstrate how to use a bath bomb, second was how to demonstrate use of other skincare spa based products, thirs was to fill out a form stating our personal details and work availability and fourth was a proper questions based group interview.
