Why your resume gets rejected before anyone reads it
You send out dozens of applications. You're qualified for the roles. Yet you don't land a single interview. The problem probably isn't your profile. It's the way machines read your resume.
ATS, the automated screening software recruiters use, reject or misrank applications because of technical mistakes candidates are completely unaware of. These ATS resume mistakes have nothing to do with your experience or your skills. They're about how your resume is built, formatted, and worded.
Here are the 10 most common mistakes that trip up ATS, and how to fix them one by one.
Mistake 1: An image-based PDF resume
The problem
Your resume is a PDF file, but the text can't be selected. That's the case for many resumes exported from Canva, Photoshop, or InDesign without the right settings. To the ATS, it's an image: it can't extract any text, any keywords, any information. Your score drops to zero.
How to fix it
Open your PDF and try to select some text. If you can't, your resume is an image-based PDF. Rebuild it in Word, Google Docs, or LibreOffice and export it as a PDF. Check that the text can be selected in the exported file.
Mistake 2: A multi-column layout
The problem
Two- or three-column resumes look elegant. But ATS read content left to right, line by line. With columns, the software mixes text from the left column with text from the right column, producing garbled sentences and missing entire chunks of information.
How to fix it
Switch to a single-column format. Every section stacked one below the other, in a logical order. It's less striking visually, but far more effective with automated filters.
Mistake 3: Creative headers or text inside graphic shapes
The problem
You put your name in a colored banner, your contact details in a circle, your section headings in shaded boxes. The ATS can't read text sitting inside those graphic elements. Your contact information, your section headings: all of it can be ignored.
How to fix it
Use plain text for all your information. Your name in bold and a larger size is enough. Section headings in bold or all caps, with no colored background or shape. Contact details in plain text at the top of the document.
Mistake 4: Missing keywords from the job posting
The problem
You send the same resume for every application without tailoring it to each posting. The ATS compares your resume to the posting: if the key terms from the ad aren't in your document, your match score is low. Why does the ATS reject your resume? Often, it's simply because the right words aren't there.
How to fix it
Before each application, read the posting carefully. Identify the skills, tools, and qualifications it mentions. Work those terms into your resume: in the profile summary, in your experience descriptions, and in the skills section. Use the posting's exact wording.
Mistake 5: A generic, one-size-fits-all resume
The problem
Your resume is well written, but it's designed to be universal. It covers all your skills evenly without highlighting the ones that match a specific role. For an ATS hunting for specific matches, a generic resume gets an average score on every posting and a good score on none.
How to fix it
Keep a complete "master" resume with all your experience and skills. For each application, create a tailored version by reordering your skills (most relevant first), adjusting the wording of your bullet points, and beefing up the experience closest to the target role.
Mistake 6: No Profile or Summary section
The problem
You start your resume straight with the Experience section. You're missing a valuable opportunity: the Profile section at the top is the ideal spot to concentrate the posting's most important keywords. It's also the first thing the human recruiter reads after the ATS screening.
How to fix it
Add a 3- to 5-line profile summary at the top of your resume, right under your contact details. It should include your professional title, your years of experience, your 3-4 key skills for the target role, and one standout accomplishment.
Mistake 7: Fancy or decorative fonts
The problem
You use an unusual font to stand out: a script font, a display font, or a rare typeface that isn't installed on every system. The ATS may misread the characters or not read them at all. Some decorative fonts encode letters in nonstandard ways, making the text partly or completely unreadable for the parser.
How to fix it
Use a standard font: Arial, Calibri, Helvetica, Times New Roman, Garamond. Every ATS reads these fonts correctly. Body text should be between 10 and 12 points.
Mistake 8: Inconsistent or missing dates
The problem
Your roles have no dates, or the dates come in different formats ("2022-2024" for one job, "March 2020 to June 2021" for another, "for 3 years" for a third). The ATS extracts dates to calculate your total years of experience and check seniority requirements. Inconsistent dates throw off that calculation.
How to fix it
Use a consistent date format throughout the resume. The "Month Year – Month Year" format (e.g., "January 2022 – March 2024") is the easiest to read. For your current role, use "Since Month Year" or "Month Year – Present".
Mistake 9: Acronyms without the spelled-out version
The problem
You write "CRM", "ERP", "KPI", "ROI", "SEO", assuming everyone knows what they mean. The ATS may know, but if the posting says "customer relationship management" instead of "CRM", the match doesn't happen. Acronym-related ATS resume mistakes are among the sneakiest: you think you've included the right keyword, but the ATS is looking for the full version.
How to fix it
Use both the acronym AND the spelled-out version at least once on your resume. For example: "Customer relationship management (CRM) in Salesforce". That covers both phrasings and improves your chances of a match.
Mistake 10: No quantified results
The problem
Your bullet points describe what you did, not what you achieved. "Managed the company's social media" offers no measurable context. Modern ATS and human recruiters alike look for concrete results.
How to fix it
For each role, identify at least one quantifiable result. No need to make anything up: think in terms of volume (number of projects, team size, number of clients), time (shorter turnaround, higher frequency), or improvement (streamlined process, better customer satisfaction). If you can't give an exact number, describe the impact concretely: "Overhauled the onboarding process, cutting it from 2 weeks to 3 days".
The recap: check your resume in 5 minutes
Before you send your next application, run through this quick checklist:
- Can the text in your PDF be selected?
- Is your resume a single column?
- Are your headers plain text, with no graphic shapes?
- Do the posting's keywords appear on your resume?
- Is the resume tailored to this specific posting?
- Do you have a profile summary at the top?
- Is the font standard (Arial, Calibri, etc.)?
- Are the dates consistent and complete?
- Do your acronyms have their spelled-out versions?
- Does every role have at least one concrete result?
If you check all 10 boxes, your resume has a good shot at getting past ATS filters. If you miss even 2 or 3, your score can drop significantly. For a step-by-step method, see our complete guide to optimizing your ATS resume in France.
