Have examples of data visualizations ready and background knowledge of different programs you’ve used for graphics and data. Knowledge of hi charts and illustrator is crucial. Know which programs you’ve used are Creative Commons accessible or can be used for commercial purposes. If you’ve created visualizations involving construction or architecture, definitely highlight that experience. Also be sure to note any writing experience, specific to curation of content or adding value to content through data and graphics. If you have experience testing or deploying e-newsletters, that’s good to mention too!
