A sample answer to question 1

What does an assistant merchandiser do, and why do you want to move into this part of retail?

An assistant merchandiser supports the merchandiser by providing the numbers and admin that keep a category running. That means producing weekly trading reports, raising and amending purchase orders, tracking deliveries against the critical path, maintaining product and price data, and flagging problems such as late stock or poor sellers. You also learn how the business works by watching how decisions are made about reorders, allocations and markdowns. I want to join this area because I enjoy working with numbers and finding a story in them, and I like the idea that my analysis helps the buyer and merchandiser make choices that customers will see on the shop floor. I'm organised, careful about detail and comfortable in Excel. I understand it can be busy, particularly at peak trading and season changes, but I see it as a great grounding for progressing to merchandiser and eventually planner or buyer roles.
