Frequently asked questions

How do I mention Python skills in a cover letter?

Don't just list Python—describe what you built with it. Mention specific frameworks, quantify results, and connect it to the job requirements.

Should I list my Python proficiency level?

Skip vague levels like "intermediate." Instead, show proficiency through accomplishments: "3 years building production Python applications" says more than "advanced Python."
