ATS & Resume Filtering

How to Avoid the Most Common Resume Mistakes That Trigger ATS Rejections

September 9, 2026 · 4 min read · By the Ghosted Team
Job hunting can feel like an endless loop of submitting applications and hearing nothing in return. The frustration is real, especially when you suspect an impersonal algorithm is dismissing your resume before it ever reaches human eyes. You're not alone in this battle against Applicant Tracking Systems (ATS) that seem more like barriers than gateways. But understanding the specific missteps that lead to ATS rejection may empower you to finally break through.

Why Basic Formatting Mistakes Get Resumes Rejected

Using complex formatting like tables, graphics, headers, and footers is a common pitfall. ATS often struggles to interpret unconventional or intricate formatting. For instance, the stylish table you used to display your skills creatively may appear as incoherent code strings to the ATS. Stick to basic text formats, clear headings, and bullet points for easy readability. Remember that the ATS first scans for the bare essentials before visual elements become a factor for humans.

The Impact of Incorrect File Types On Your Resume Submission

It seems small, but submitting a file in the wrong format could mean an instant rejection. Most ATS can seamlessly process .docx and .pdf files, but a .jpg or .zip file confounds them. An applicant’s resume submitted as a PDF, for example, may get through, whereas an unconventional PDF style might not. Always check job postings for preferred file types, and stick to those. When in doubt, default to .docx to maximize compatibility.

How Key Phrases and Keywords Influence ATS Decisions

The ATS searches for phrases that match the job description. A mismatch here could derail your application, even if you're the perfect fit. If the job posting mentions 'project management' and 'budget oversight,' include those exact terms in your resume. Saying you have experience 'coordinating team efforts and managing fiscal responsibilities' might not be enough. The ATS looks for exact matches, so mirroring the job posting’s language can be advantageous.

The Consequences of Not Tailoring Your Resume for Each Job Application

A generic resume might speed up your application process but often at the cost of relevance, an important factor for ATS. Tailoring your resume for each job means more than just tweaking the summary; it involves aligning your experiences with the specific needs outlined in the posting. For example, if one role emphasizes 'leadership skills,' your bullet points under previous roles should highlight related experiences. The more your resume speaks directly to the job's demands, the better its chances of catching the ATS's 'eye'.

Understanding the Significance of the Right Amount of White Space

Resume crowded with text can confuse both ATS and human reviewers. Overloading a resume with too much information may cause the ATS to misplace or overlook important content. Adequate white space enhances clarity and makes it easier for ATS to break into sections. A congested resume is like an incomprehensible text block to the system. Structures like bullet points, consistent headings, and natural breaks improve scannability significantly.

Common Font and Style Choices That Lead to Application Rejections

Unconventional fonts or excessive use of italics, underlines, and other stylizations can disrupt ATS parsing abilities. Stick with widely used fonts like Arial, Times New Roman, or Calibri at a size that’s easy to read. Adding flair through fancy fonts or colors may seem appealing, but standard readability is what counts. Clear presentation and easy readability trump all. Highlight crucial sections with bold text instead of relying on a different color.

Revise These Commonly Overlooked Sections to Avoid ATS Pitfalls

Sections like 'objective' statements, which are often outdated, can hinder an ATS. Instead, use this space to provide a ‘summary’ that aligns with role prompts. Your contact information is also vital; simply start with your full name, followed by your email and phone number. Avoid excessive details like home addresses unless explicitly requested. Keeping these sections concise and relevant can prevent unintentional ATS barriers.

How to Assess and Revise Your Resume Before Submission

Regular revisions of your resume using a diagnostic tool could radically improve your application’s success rate. Consider running your resume through a free diagnostic tool to capture errors you might overlook. These tools can offer insights into ATS compatibility, keyword density, and formatting issues. Addressing these facets before submission can significantly improve your chances of catching an employer's eye. Sometimes a little refinement is all that's needed to cross that first hurdle.
