Your best work may sit behind a confidentiality agreement, inside a former employer's system or in a customer relationship you cannot name. That does not mean you need to publish it to prove you are capable. Build evidence that explains your thinking while respecting the people and organizations involved. This is a practical portfolio method, not a legal judgment about what your agreement permits.
Decide what is yours to show
List the material you want to use and who owns or controls it. A slide you created at work is not automatically yours to publish. Check the relevant agreement and policies. If permission is uncertain, ask the authorized owner or get qualified advice before sharing. A recruiter asking for a sample does not override an existing obligation.
Do not rely on removing the logo alone. Names, unusual figures, screenshots, file metadata and combinations of small details can reveal a client or project. If you cannot confidently separate the method from protected information, choose a different example. Avoid uploading confidential files to online editing or AI services just to make them look anonymous.
Create a clearly labelled demonstration
A fictional sample can show how you approach a problem without pretending it was paid work. Give it a visible label such as independent demonstration using synthetic data. State the task, assumptions, tools, decisions and limitations. Use data you created yourself or material whose licence permits the intended use.
For example, a fictional support dashboard could use invented ticket categories and volumes. Explain how you would define a useful metric and what the chart cannot tell a manager. Do not claim that a real company used it or that it produced savings. A small, well-explained sample is more credible than a large invented case study.
Show decisions, not a mystery screenshot
Build each entry around a question: what problem were you solving, what options did you consider and why did you choose this approach? Show a safe input, a small piece of the process and a finished output. Include one limitation or tradeoff. This gives an interviewer something concrete to discuss.
Make your own contribution explicit if the work was collaborative. You can describe responsibilities in general terms without naming clients or disclosing results. Where you have permission to show an excerpt, record its scope and keep the original approval. Permission to show one page privately is not necessarily permission to publish the whole project online.
Prepare a safe interview version
Before a call, check the exact files, links and browser tabs you will share. Use a separate presentation copy without private notes or hidden sheets. Test access from another browser so you know what a viewer can open. Do not grant broad folder access when one permitted file would do.
If asked for protected details, explain the boundary calmly and offer the demonstration instead. You can say that you can discuss your method but cannot share a client's material. The National Careers Service encourages factual examples of skills; those examples do not have to expose confidential records. Your handling of the boundary is part of how you present your professional judgment.
