🚫 Error #1: Using Formats the ATS Cannot Read

The first and most serious mistake is sending a resume in a format incompatible with ATS. According to a Capterra study (2025), 34% of CVs are automatically rejected due to formatting.

Formats that work ✅ and that do NOT work ❌:

✅ DOCX (Word) – Compatible with 98% of ATS.
✅ Simple PDF – Works well, but avoid scanned PDFs or those with graphic layers.
❌ JPG, PNG or images – The ATS cannot extract text from images.
❌ PDF with graphic design (Canva, Photoshop) – Columns and graphics confuse the parser.
❌ Web pages or HTML portfolios – Not accepted on most job portals.

📌 Critical tip: Before sending your resume, run it through a free ATS simulator like Jobscan or ResumeWorded. If the parser extracts illegible or disorganized text, your CV will be rejected. For a deeper review of this issue, we recommend checking the article on how to prevent your CV from being rejected by an ATS, where real cases of CVs that never reached a recruiter are analyzed.

🚫 Error #2: Omitting Specific Keywords from the Job Posting

ATS work like search engines: they scan your resume for keywords that match the job description. If you don’t include them, your score will be low.

How to identify the right keywords (step by step):

Read 10 similar job postings on LinkedIn or Indeed.
Extract the most repeated words: hard skills (e.g., “Python”, “Salesforce”), certifications (“PMP”, “CPA”) and tools (“Tableau”, “SAP”).
Include synonyms: An ATS looks for variations. Example: “project management” / “gestión de proyectos”.
Use the skills section to group keywords.
Don’t abuse keyword stuffing: Include them naturally.

📌 Practical example: If the job posting asks for “Experience in bilingual customer service”, your CV must contain exactly “customer service” and “bilingual” (English/Spanish).

🚫 Error #3: Using Tables, Columns, Graphics, or Text in Images

The most common ATS (Workday, Taleo, Greenhouse, Lever) convert your resume into plain text. Tables, columns, graphics, logos, and text inside images get lost or generate unreadable characters.

Safe structure for ATS:

✅ Linear layout (single column).
✅ Standard fonts: Arial, Calibri, Times New Roman, Helvetica.
✅ Font size: 10 to 12 points for normal text, 14 to 16 for headings.
✅ 0.5 to 1-inch margins on all four sides.
❌ No custom bullets (use simple hyphens or asterisks).
❌ No headers or footers – Many ATS ignore these sections.

📌 Key fact: If you use Canva or Adobe InDesign, export to DOCX and verify that the text is selectable. If you can’t copy the text with your cursor, the ATS won’t be able to read it either.

🚫 Error #4: Not Customizing the Resume for Each Application

Sending the same resume to 100 job openings is the most common mistake among candidates. Recruiters and headhunters immediately detect a generic CV, and ATS score it low because it doesn’t match the specific keywords.

How to customize in 5 steps:

Copy the job description into a document.
Highlight the 10 most important keywords.
Modify your professional profile to include those words.
Adjust your achievements section to reflect the job’s responsibilities.
Save each version as “CV_LastName_FirstName_Company_Date.docx”

📌 Expert tip: Senior recruiters in the USA value a CV tailored to the company more than a “perfect” but generic CV. Investing 10 minutes per application increases your chances of an interview by 40%. If you want to learn more about which formatting errors to avoid when sending your CV to large companies, the site offers a very useful checklist based on the experience of Fortune 500 recruiters.

🚫 Error #5: Using Unclear or Creative Section Headings

ATS look for standardized sections. If you use headings like “My Path”, “Unique Skills”, or “Relevant Experience”, the system may not recognize them and discard that information.

Correct headings for ATS (use these exactly):

✅ Professional Profile or Professional Summary
✅ Work Experience (not “Work History”)
✅ Education or Academic Background
✅ Skills or Technical Competencies
✅ Certifications or Languages
❌ Aptitudes, Abilities, Career Path (too ambiguous)

📌 Date format: Always use MM/YYYY (e.g., “Jan 2020 – Present”). Avoid “2020-present” or “today”.

🚫 Error #6: Including Irrelevant or Prohibited Personal Information

In the USA, certain personal data on your resume can create bias and even violate state laws. Moreover, recruiters consider them unprofessional.

📢 Share this article if you think it could help someone else.

What NOT to include under any circumstances:

❌ Photo (in New York and California it is illegal to request it)
❌ Date of birth or age
❌ Marital status, religion, race, or sexual orientation
❌ Social Security number
❌ Full address (city and state are sufficient)
❌ Personal references (a note “References available upon request” is enough)

What TO include: Full name, phone number, professional email address, city and state, LinkedIn link (optional), portfolio (if applicable).

🚫 Error #7: Sending the File with a Generic Name

The last but not least error is the file name. “CV.pdf”, “MyResume.docx” or “Resume_final_v3.docx” are names that recruiters hate and that some ATS mishandle.

Correct format for the file name:
📌 LastName_FirstName_JobTitle_Company_Year.docx

Examples:

Perez_Juan_DataAnalyst_Amazon_2026.docx
Garcia_Maria_ProjectManager_Deloitte_2026.pdf

📌 Why it works: Makes organization easier for the recruiter, shows professionalism, and is compatible with all ATS.
