For roles in technical fields like data analysis, where is demonstrable experience using Python or R often required to be shown via a portfolio?

On a platform like GitHub

For specialized technical roles such as data analysis, where the degree itself is often only considered the minimum entry requirement, hiring managers frequently look for concrete evidence of skill application. This evidence is typically demonstrated through tangible experience using programming languages like Python or R, often showcased via personal analysis projects. The recommended way to present this evidence is by hosting the portfolio on a platform such as GitHub, which allows employers to review actual work, data cleaning processes, and visualization outputs, thereby significantly shifting employer interest toward the candidate.
