How to Compare a Resume with a Job Description, Step by Step
You can compare a resume with a job description with a pen and ten minutes. Doing it by hand once also makes any automated result easier to interpret.
Step 1: list the requirements
Copy the posting into a document. Underline everything the employer asks of you: skills, tools, experience, responsibilities. Then mark each as a must-have or a nice-to-have, using the posting’s own words ("required", "preferred") and how often it repeats.
Step 2: find your evidence for each
Next to each requirement write where your resume shows it. Be strict: only count a place where you describe doing the thing. A skills list is a weak signal; a bullet about work is a strong one.
- Strong: a bullet describes real work using it.
- Partial: the term appears but with no detail, or only related experience exists.
- Gap: nothing in the resume supports it.
Step 3: sort the gaps into two kinds
A gap you can fix is experience you have but never wrote down. A gap you cannot fix is experience you do not have. Only the first kind is a reason to edit.
Step 4: decide
If the central duty is a gap you cannot fix, the job is a stretch. If several secondary requirements are gaps, that is common and not a reason to skip it. If nearly everything is strong or partial, spend your time on the writing.
"Python" (strong: two bullets), "stakeholder reporting" (partial: mentioned once, no detail), "Kubernetes" (gap you cannot fix), "SQL" (gap you can fix: you used it daily but never wrote it down).
Using a tool for the same job
A matching tool does the first three steps quickly and consistently. JobSealer’s free check lists strong matches, partial matches and gaps for a resume and one job description, with no sign-in. It reads text only, so the decision in step 4 stays yours.
Common traps
- Treating the job title as the requirement. The duties and the tools tell you more.
- Counting a skills-list mention as full evidence. It only shows you know the word.
- Reading "preferred" as "required" and talking yourself out of a good fit.
- Reading "required" as negotiable when it is a legal or licensing condition.
- Comparing against an outdated copy of your resume.
Key Actionable Takeaways
- Separate must-haves from nice-to-haves.
- Count only evidence that describes real work.
- Fix gaps that are missing writing; do not fake gaps that are missing experience.
Frequently asked questions
- How long should a comparison take?
- About ten minutes for a typical posting once you have done it a couple of times.
