Applying for a Assistant Buyer job in the UK? Here is what you are likely to be asked. These questions come from our Assistant Buyer question bank of 16 questions, written for UK employers at junior level.

Eight Assistant Buyer interview questions, and what the interviewer is thinking

1. What does an assistant buyer do on a typical day, and why do you want to do it?

Why they ask: They want to check you understand that the role is part analysis, part admin and part product, not just choosing nice things.

2. A garment costs £6.00 landed and retails at £20 including VAT. What is the initial margin, and how did you work it out?

Why they ask: Basic margin maths is used daily, and an assistant buyer must do it quickly and accurately.

3. How would you use Excel to analyse a weekly sales report and find the best and worst performing styles?

Why they ask: Most assistant buyer work depends on spreadsheet skills, so they check practical competence.

4. What would you expect to see in a weekly trading report, and what actions might it lead to?

Why they ask: Trading meetings drive buying decisions, so they test your commercial reading of numbers.

5. How would you carry out a competitor shop, and what would you take from it?

Why they ask: Competitor and market awareness is a daily expectation for junior buying staff.

6. What are the most common mistakes when raising purchase orders, and how do you prevent them?

Why they ask: PO errors cause late, wrong or overpriced stock, and the assistant is usually the person raising them.

7. A supplier tells you that a delivery for a major promotion will be a week late. What do you do?

Why they ask: It tests problem solving, communication and escalation in a real supply chain situation.

8. Tell me about a time you used data to spot a problem or opportunity that others had missed.

Why they ask: They want evidence of analytical curiosity and the ability to turn numbers into action.

A sample answer to question 1

What does an assistant buyer do on a typical day, and why do you want to do it?

A typical day starts with the previous day's sales and stock figures, so I can flag any lines flying or stalling before the buyer's trading meeting. After that I might update the range plan, chase suppliers for samples or delivery dates, raise or amend purchase orders, and check costs against the agreed cost sheet. I spend time on product data, making sure new styles are set up correctly on the system, and I help prepare range presentations and sample reviews. I may also shop competitors or research trends, and liaise with the merchandiser, design and technical teams. I want to do it because I enjoy the mix of creative judgement and commercial discipline, and I like that you can see the result of your work on the shop floor or website within weeks. It is also a clear route to buyer, and I would be keen to learn from a strong buyer how to negotiate and build a range.

Common mistake to avoid: Describing it as only shopping for products; no mention of data or admin
