Start with the vacancy. Mark the responsibilities it names, then match each one to a truthful project, placement, freelance brief or academic example. For each example, note the context, your own actions and reasoning, the result and what you learnt. Use these notes as prompts rather than a script.
For UK interior designers, relevant experience may include understanding a client's ideas and advising on space, colour schemes, fabrics, fittings or furniture. The work can also include preparing detailed 2D and 3D plans, drawings, designs and models for spatial planning and presenting design concepts to clients. Choose only examples that reflect what you actually did.
Interior designers may estimate materials and timescales, source products and suppliers, coordinate contractors or manage a project through delivery, although the extent of project-management responsibility varies by role. Review any genuine examples that show design knowledge, creative problem-solving or space-planning skills. You may also have work that involved knowledge of building and construction, interior systems, materials, equipment or furnishings.
Interior designers may use design software for detailed 2D and 3D plans, schematics, drawings and design documents, but the specific software depends on the employer and role. Be precise about the tools you used, what you produced and your level of responsibility. Prepare an example of communicating or collaborating with a client, colleague or project partner if you have one.
Compare your notes with your Interior Design CV so that dates, scope and ownership remain consistent. Practise aloud without memorising complete answers. If your interview is remote, test your connection, camera and microphone beforehand and keep any permitted notes close by.
