Eight Merchandiser interview questions, and what the interviewer is thinking

1. Talk me through your weekly trading routine as a merchandiser.

Why they ask: Interviewers want to hear a disciplined, data-led rhythm rather than ad hoc firefighting.

2. How would you forecast sales for a new line with no sales history?

Why they ask: Forecasting new products is a daily challenge, and they test method and judgement.

3. How are stores clustered or graded, and how does that affect which products and how much stock each store gets?

Why they ask: Store-level ranging is central to merchandising and drives availability and sales.

4. What is auto-replenishment, and how do min-max levels and presentation minimums work?

Why they ask: Replenishment logic keeps shelves full and protects margin, and merchandisers own the parameters.

5. How do you measure forecast accuracy and bias, and what would you do to improve them?

Why they ask: Forecast quality drives stock levels and availability, so they test analytical rigour.

6. How do you plan stock for a promotion, and how do you deal with cannibalisation and the risk of running out?

Why they ask: Promotions can create big swings in sales and stock, and an experienced merchandiser should plan them carefully.

7. A store manager rings to complain that they are always short of your best sellers and says other stores are favoured. How do you respond?

Why they ask: It tests communication, fairness and a data-based approach to stakeholder concerns.

8. Tell me about a time you improved availability or forecast accuracy for a category.

Why they ask: They want evidence of a measurable operational improvement.

A sample answer to question 1

Talk me through your weekly trading routine as a merchandiser.

On Monday I review the previous week's trading, looking at sales, units and margin against forecast by category, style and store grade, plus availability and stock cover. I pick out lines moving faster or slower than expected and check for causes such as weather, promotions or stock gaps. I then produce a short summary for the trading meeting, with proposed actions: replenishment orders, stock transfers between stores, adjustments to forecasts, or flags to the buyer for markdowns or reorders. During the week I monitor daily sales and stock for key lines, manage deliveries from suppliers and the distribution centre, and resolve exceptions such as stock showing as available but not reaching the shop floor. I also update forecasts and the plan for upcoming promotions and seasonal events, and meet with the supply chain team on delivery slots. At the end of the week, I check actions have been completed and record learnings. I aim to be proactive, so that the buyer and store managers get solutions rather than reports.

Common mistake to avoid: Describing only reporting; no mention of acting on the data
