How to Prepare an Interview Presentation

An interview presentation starts with the assignment, not the slide design. Before making a deck, work out what you have been asked to explain, what information you may use and how much time you have. A polished presentation that answers a different question is still off brief.

This guide offers a planning sheet, a suggested structure and a rehearsal method for a presentation set as part of an interview. It is different from a portfolio walkthrough, where you explain existing samples of your work. Follow the employer's instructions where they differ from these suggestions. No slide count or speaking formula guarantees an interview outcome.

Turn the brief into a checklist

The UK's National Careers Service advises candidates asked to present to read the instructions carefully. Convert those instructions into a working checklist:

• Question: What exactly must the presentation answer?
• Audience: Who will listen, and what background knowledge does the brief assume?
• Deliverable: Slides, a demonstration, a document or another format?
• Timing: How long is the presentation, and are questions included?
• Evidence: Which supplied materials or external sources may you use?
• Submission: What file type, deadline and delivery method are specified?

Mark anything unknown rather than filling it with a guess. If timing is ambiguous, ask a focused question such as whether the stated duration includes discussion. If you need a different format, more time or another adjustment, ask the organiser early; do not assume the request has been agreed. Check the assessment's rules about outside help and AI before using either; do not assume that permission to research means permission to have someone else complete the task.

Decide on the answer before building slides

Write a one-sentence answer to the brief. Then list the evidence needed to support it. A suggested structure is:

1. State the question and your main answer.
2. Explain the evidence or observations behind it.
3. Compare the relevant options and their trade-offs.
4. Give your answer or recommendation, its limits and the next check needed.

This is a planning aid, not a mandatory sequence. A teaching demonstration or technical explanation may need a different structure. Remove any section that does not help answer the actual brief.

Fictional planning example: the assignment asks how to improve an internal handover. Your proposal is to test a shared handover checklist with a small team. You can explain which missing information it would address and how you would collect feedback. You cannot claim that the checklist has already reduced errors if no test has taken place.

Label assumptions beside the claims they affect. If a recommendation depends on staffing information you were not given, say so. Do not invent customer interviews, internal data, budgets or survey results to make the presentation look researched.

Make evidence readable and safe to share

Give each slide one clear job: explain a point, show evidence or compare options. Use headings that tell the audience what to notice. If text is too small to read comfortably in a practice run, simplify the slide rather than relying on people to zoom in.

Keep a source note for every external fact: the source, publication date where available, link and the exact claim it supports. Distinguish a source's findings from your own recommendation. Check the original source rather than copying a summary you cannot verify.

Use only material you have permission to share. If permission is unclear, use a clearly labelled fictional illustration or omit it. Inspect speaker notes, comments and hidden slides as well as the visible deck before submitting it.

Rehearse the delivery and the questions

Run through the presentation aloud using the equipment and file format you expect to use, where possible. Time the whole talk, including transitions. If it runs long, remove a secondary point; do not depend on racing through the final slides.

For each recommendation, practise answering three questions: What supports it? What could change it? What would you check next? If you do not know an answer, say what is missing instead of defending a guess.

Prepare a simpler verbal summary in case the slides cannot be displayed. If the organiser permits a backup file, save it in the requested format and check that it opens. Do not send confidential material to an unapproved tool just to convert it.

Before submission, compare the finished file with your checklist: correct question, required format, honest evidence, readable content and agreed timing. Finish with a complete timed rehearsal. Ask a practice listener to explain your main answer back to you; use any mismatch to decide what needs clarifying.
