A sample answer to question 1

Why do you want to be a merchandising assistant, and what do you think the job involves?

I enjoy retail and I like working with numbers, so merchandising feels like the place where both meet. As I understand it, a merchandising assistant supports the merchandiser and buyer by keeping the product information, orders and reports accurate and up to date. That could involve setting up new products on the system, raising purchase orders, updating delivery dates, producing weekly sales and stock reports, and chasing suppliers or the warehouse when something is late. Every task affects what customers can buy, so accuracy matters. I'm organised, careful about detail and comfortable with Excel from my studies and part-time work. I also like that the role offers a clear route to learning how a retailer really makes money, from cost price to margin to stock, and progressing to merchandiser. I'm aware it can get busy at peak times, but I'm happy to ask questions, take ownership of my tasks and learn from the team.

Common mistake to avoid: Treating it as just data entry; no interest in the commercial side
