Choose one question
Begin with a question that genuinely shaped your work. It may be a confusing report, a change in search intent or a request that needed clarification. A small example with a clear explanation is useful because another person can follow it without knowing your account history.
Make your part distinct
State what you personally investigated, decided or produced. Then acknowledge what others contributed. This makes the example more credible and gives a conversation room to explore teamwork. Avoid using a team result as if you created every part of it alone.
Describe the limits
An observation is not always proof of a cause. Explain what information was available, what else could have affected the outcome and what you could not determine. You do not need a dramatic success story to show careful judgement.
Protect the original material
Use only material you are authorised to share. Remove customer information, account identifiers and commercially sensitive detail. If the original cannot be shown, describe the approach in general terms or create a clearly labelled fictional exercise.
Leave a useful next step
Finish with the question you would investigate next. This helps connect the example to an ongoing learning process. A thoughtful next step can show that you understand the difference between completing a task and exhausting a problem.
