Build a data project from three job descriptions
If you want a data project that shows what you can do, start with three job descriptions for roles you actually want. Mark the skills, tools and business tasks that keep coming up, then find where they overlap. That overlap gives you a direction for the project.
Write that direction as a question you can answer. Find data that fits it and limit the scope. For example, organise a sales dataset and make one recommendation. Before you publish a conclusion, check the dates the source table covers. A missing day of data might explain the change you noticed.
When you present the result, explain what you were trying to find out, what the data could tell you, which choices you made and how you checked your answer. Rehearse the explanation aloud before an interview.
