A sample answer to question 1

Why do you want to work as a customer assistant here?

I enjoy helping people and I like being busy, so working on the shop floor suits me. I have shopped here for years, and what I like is that colleagues are friendly and the store is always well stocked and tidy, which is the sort of standard I would like to help maintain. I think the job is more than just using the till, because customers rely on you for advice, finding products and sorting out problems, and it is satisfying when someone leaves happy. I am reliable, I am happy to work flexible hours including weekends, and I am quick to learn. I also like that retail offers a career path, with opportunities to become a team leader or move into other areas of the business, and I would like to learn those skills. I would bring a positive attitude and a willingness to help wherever needed.

Common mistake to avoid: Saying it is just a job; criticising a competitor
