Why Format Matters for ATS
Even with perfect keywords and experience, poor formatting can cause your resume to be rejected by ATS. The system needs to parse your information correctly - complex layouts confuse the algorithm and result in lost data.
📊 The Impact
75% of resumes with fancy designs or complex formatting fail ATS parsing, even when the candidate is qualified.
