A sample answer to question 1

What does a typical day as an Online Merchandiser involve?

To start, I by checking yesterday's trading: revenue, conversion, add-to-basket rate and top and bottom sellers by category, comparing against targets and the same day last year. I look for stock-outs, products with strong traffic but poor conversion, and anything that needs a quick fix. I then update the website: reordering category pages, adjusting sort rules and boosting or burying products, refreshing homepage banners and promotional slots, and checking that product data, images and prices are correct. I liaise with the buying team about stock positions and upcoming deliveries, with marketing on campaigns and email content, and with the content team on product descriptions and SEO. I plan upcoming launches and promotions in the trading calendar and review A/B tests. Later I might prepare a short trading report with recommendations. It is a blend of analysis, creativity and quick commercial decisions.

Common mistake to avoid: Describing it as simply uploading products; Not mentioning data and targets
