First Impression:

Technically competent with good project breadth, but bullet points lack measurable outcomes.

Likely Screen-Out Reasons:

Missing quantified impact in 60% of bullet points
No mention of agile or scrum methodologies
Generic action verbs like 'worked on' and 'helped with'

Estimated Time to Reject: 22 seconds

What a Recruiter Would Want to See:

Concrete metrics: latency reduction, uptime %, users served
Leadership signals: mentoring, code reviews, architecture decisions
Technology depth: system design choices and trade-offs

What to Fix First

Add quantified metrics to every bullet point (e.g., reduced latency by 40%)+8 to +12 points
Include missing keywords: microservices, CI/CD, agile, TypeScript+5 to +9 points
Replace generic verbs with strong action verbs (architected, optimized, scaled)+4 to +6 points

With a few targeted improvements, your resume could score 85+ and dramatically increase interview callbacks.

How an ATS Scanner Works and How to Read Your Results

What an ATS scanner actually checks

An applicant tracking system parses your resume into structured data — name, contact info, work history, skills, dates — before a recruiter ever sees it. An ATS scanner mimics that parsing step to find where the software might choke: unreadable formatting, mislabeled sections, tables or columns that scramble the read order, and missing keywords. Resumly's scanner uses AI to evaluate these factors and surface them as inline comments on your document.

Why inline comments beat a single score

Most scanners hand you a number and leave you guessing. Resumly's ATS scanner instead attaches comments directly to the lines that matter, so a vague 'improve keywords' becomes 'this bullet has no measurable outcome' on the exact bullet in question. Seeing feedback in context makes it far faster to act, because you're editing the line while you read the note about it.

Formatting that breaks ATS parsing

The most common reason a resume scans poorly is layout the parser can't follow. Multi-column designs, text boxes, graphics, headers and footers with critical info, and non-standard section names all risk being dropped or jumbled. Stick to a single-column layout, standard headings like 'Experience' and 'Education,' and conventional date formats so the scanner — and the real ATS — reads everything in order.

Keywords and the job description

Applicant tracking systems often rank or filter resumes by how well they match the role's keywords. The skills, tools, and titles in the job posting should appear naturally in your resume where they're genuinely true, especially in your experience bullets rather than only in a skills list. Avoid keyword stuffing — it reads as spam to humans and adds nothing once a real recruiter opens the file.

What to do after you scan

Treat the scanner's inline comments as a punch list: fix the highest-impact parsing and formatting issues first, then tighten keywords and weak bullets. Re-scan after edits to confirm the issues cleared and nothing new was introduced. Remember the tool flags compatibility problems — the judgment of which fixes matter most for your target role still belongs to you.

Why Use the Resume ATS Scanner?

Traditional ATS checkers give you a score and a list of issues — but it can be hard to know exactly where to make changes. The Resume ATS Scanner takes a different approach by placing feedback directly on your resume, so you can see problems in context. It's like having a career coach look over your shoulder and point at each line that needs work.

Resume ATS Scanner — Frequently Asked Questions

Find answers to the most common questions about the Resume ATS Scanner

An ATS scanner is a tool that checks how an applicant tracking system will read and parse your resume. It looks for formatting, structure, and keyword issues that could cause the software to misread your information or rank your application lower. Resumly's free ATS scanner does this with AI and shows the problems as inline comments on your resume.

Yes. You can scan your resume for ATS compatibility for free with no payment required. Upload your resume and you'll get an AI-powered analysis with inline comments showing what to fix.

Upload your resume to the ATS scanner and let the AI analyze it. Within moments you'll see inline comments placed directly on the lines that have parsing, formatting, or keyword issues, along with guidance on how to improve each one.

It evaluates the factors an applicant tracking system cares about: whether your formatting and sections can be parsed cleanly, whether your headings and dates follow standard conventions, and whether your keywords align with what the role is looking for. The results appear as comments attached to the relevant parts of your resume.

They're essentially the same thing — both terms describe a tool that reads your resume to flag problems. 'ATS scanner' emphasizes compatibility with applicant tracking software, while 'resume scanner' or 'CV scanner' is the more general phrasing. Resumly's tool covers both: it scans your resume specifically for ATS readability.

The usual culprits are formatting the parser can't follow — multi-column layouts, tables, text boxes, graphics, or critical details hidden in headers and footers — plus non-standard section names and missing keywords. The scanner's inline comments point to the specific lines causing each problem so you can fix them one at a time.

No sign-up is required to scan your resume. You can run the free ATS scan and review the inline feedback without creating an account.

Yes — that's the point of the inline comments. Instead of a single vague score, the scanner attaches specific feedback to the exact lines and sections that need work, so you know precisely what to change and why.

No tool can guarantee that, because different employers use different applicant tracking systems with different settings. What the scanner does is catch the common parsing, formatting, and keyword issues that trip up most systems, dramatically improving your odds of being read correctly.

Use a single-column layout with standard section headings, conventional date formats, and no tables, text boxes, or images in critical areas. Mirror the job description's relevant keywords naturally in your experience, and avoid keyword stuffing. Then re-scan to confirm the issues cleared.

Upload the version of your resume you actually plan to send to employers so the scan reflects what an ATS will receive. After reviewing the inline comments and editing, re-run the scan on the updated file to verify your fixes worked.

Scan it whenever you make meaningful edits or tailor it to a new role, and always after a redesign or format change. Re-scanning confirms your fixes landed and catches any new issues introduced while editing.
