Why 75% of Resumes Are Never Seen by Humans
A 2023 Harvard Business School study found that 75% of large-company candidates are eliminated by ATS before a recruiter reads them. These systems parse your resume for exact keyword matches against the job description.
The fix is not to "game" the system - it's to use the right language. If a job description says "data visualization" and your resume says "creating charts," an ATS might score you as 0% for that skill because the exact term doesn't match.
How Our ATS Score is Calculated
We use a TF-IDF (Term Frequency-Inverse Document Frequency) model - the same statistical approach used in professional HR software. This gives a more accurate picture than simple keyword counting:
- TF (Term Frequency): How often a keyword appears in the job description (shows importance)
- IDF (Context Weight): Rare, specific terms (like "Kubernetes" or "HIPAA") score higher than common words
- Match Score: Percentage of high-weight JD keywords found in your resume
