ATS resume checker: test your resume against the actual posting
Recruiters don't read resumes top to bottom — they search the applicant tracking system for the skills listed in one specific posting. An ATS resume check is only useful if it compares your resume to that posting. JobLab does exactly that: score before, honest tailoring, score after.
The two failure modes of a resume in an ATS
Parsing failure — exotic layouts, tables, and graphics can scramble how the system extracts your work history. This is rarer than the internet claims, but real.
Search invisibility— the far more common one. The recruiter filters hundreds of applicants by the posting's key skills. If your resume uses different words for the same skill, you never appear in their shortlist.
Why one resume per posting beats one resume for all
The same experience can be framed a dozen honest ways. A data analyst who “built dashboards in Looker” also “delivered self-serve BI reporting” — which phrasing wins depends entirely on the posting. Tailoring per application is tedious by hand, which is why most people skip it and lose to the few who don't.
What the JobLab check gives you
A baseline match score for your current resume vs. the posting.
A tailored rewrite that remaps your real experience to the posting's requirements and vocabulary — nothing invented.
The new score, with a requirement-by-requirement audit.
Locked gaps shown honestly, so you know what to address in the cover letter or interview instead of hoping nobody notices.
After the check, JobLab can carry the same application forward: cover letter, screening answers, finding the hiring team, and interview rehearsal — see how the full flow works.
Test your resume against a real posting — free
Paste your resume and the job posting. You get the baseline match score, a tailored rewrite mapped to the posting's language, and the score lift — in a couple of minutes. First optimize is free, no card.
Two things matter: clean parseable formatting, and keyword match with the specific posting. Formatting is table stakes — the match is where interviews are won. Run your resume against the actual job posting and look at which required skills appear in your resume in the recruiter's wording.
What keywords should my resume include?
The ones in the job posting you're applying to — role titles, hard skills, tools, and the exact phrasing the company uses. That's why the same resume should be tailored per application rather than sent identically everywhere.
Does JobLab keep my resume?
For a free guest check, the run is stored temporarily so you can claim it if you create an account; unclaimed runs expire automatically. With an account, your master resume is stored securely so you can tailor it to new postings in one click.
Can an AI resume rewrite get me rejected for lying?
It can if the tool invents things. JobLab never fabricates employers, dates, titles, or metrics — it remaps your real experience to the posting's language and openly marks requirements you don't meet as locked gaps.
