What the resume does
A resume is a structured record: titles, dates, skills, projects, outcomes. Recruiters skim it for pattern matching and credibility.
What the cover letter does
A cover letter connects the dots. It explains why this role, this employer, and this experience fit together. It is especially useful when the fit is not instantly obvious from the resume alone.
Why the two should reinforce each other
A cover letter should not repeat the resume line by line. It should deepen one or two points that matter most for the target role.
Frequently asked questions
Can I skip the cover letter?
+
If the employer clearly does not want one, yes. If they ask for one, treat it as part of the evaluation.
Should the cover letter match the resume tone?
+
Yes. They should feel like they came from the same person.
