Make your resume and cover letter tell one story
A cover letter should extend the resume, not narrate it line by line. Both documents need the same factual foundation and target-job context, while doing different communication jobs.
Give each document a role
The resume provides structured evidence across your history. The cover letter selects one or two examples, explains motivation and fit, and connects the evidence to the organization’s current need.
Share the source context
Use the same job description, resume version, titles, dates, and metrics for both. This prevents an AI-generated letter from introducing technologies, responsibilities, or claims missing from the resume.
- Same target role
- Same verified facts
- Complementary examples
- Consistent seniority and tone
Avoid repetition
Do not paste bullet points into paragraphs. Add reasoning: why the challenge mattered, what trade-off you made, or why the work prepares you for this role.
Review as a pair
Open both documents before submitting. Check that the strongest requirement is answered, names and titles agree, and the letter does not promise experience the resume cannot support.
