Lush interview questions

I applied for the job through submitting my CV and cover letter to their email after seeing a poster in the store window. I was then invited to a large group interview a week later, where there was around 15 of us. Firstly, we had to get with a partner and then introduce their name, age, who would play them in a movie and why, and their favourite Lush product and why. They then showed us how to demo some of the products (bath bomb, bubble bar, massage bar and scrub), and then we had to choose a product from the store and demo it to the group. Afterwards we were then briefly interviewed individually. Overall, the interview lasted around 2 and a half hours, making it feel very draining. We then heard back the same night via email, as they were doing trial shifts the next day and the day after, as they wanted new staff to start immediately.
