Why Your Resume Gets Rejected by ATS

Applicant Tracking Systems (ATS) like Workday, Taleo, Greenhouse, and iCIMS automatically filter resumes before recruiters see them. Here's why yours might be getting rejected:

🔍

Missing Keywords

ATS software scans for specific keywords from the job description. Missing them means automatic rejection, even if you're qualified.

⚠️

Bad Formatting

Tables, columns, headers, fancy bullets, and special characters break ATS parsing. Your resume becomes unreadable to the system.

📊

No Quantified Results

Vague achievements get low scores. ATS and recruiters favor specific metrics: percentages, dollar amounts, team sizes.
