ATS Optimization

Most resumes are scanned by an applicant tracking system before a human ever reads them. The ATS extracts skill tokens from your resume, compares them against the tokens in the job description, and surfaces the top matches to the recruiter. If your phrasing does not match the job posting's vocabulary, you can have the exact right experience and still rank low.

The practical fix: copy the job description into a scratch document, highlight every noun-phrase skill ("supplier consolidation", "demand forecasting", "incident response"), and make sure the matching phrases appear verbatim in your resume's Experience or Skills sections — not just in a Summary. Skills sections alone are weighted less than skills demonstrated inside a bullet next to a measurable outcome.

Be honest with the matches. A 70% keyword overlap with truthful evidence beats a 100% overlap that falls apart in the first interview. ATS keyword stuffing also triggers a "low credibility" flag in some newer systems that score resume coherence.

Formatting Best Practices

Recruiters scan a resume in roughly eight seconds on the first pass. That scan covers: most recent job title, company name, dates, and the first bullet under your most recent role. Optimize those four surfaces ruthlessly. Lead the first bullet with your strongest, most-quantified accomplishment — even if it is not the most recent thing you did.

One column. One font. Plain section labels. Dates right-aligned on the same line as the role. No tables, no icons-as-bullets, no two-color schemes. Save as PDF from your word processor; never export a printed-and-scanned PDF because those rasterize and become invisible to most parsers.

Length: one page if you have less than ten years of experience. Two pages if you have more, but only if every bullet on page two earns its place. Hiring managers will not penalize a one-page resume; they will penalize a padded two-page resume.

Common Mistakes

The most common resume failure is not a typo — it is vague language. "Improved customer satisfaction" tells the reader nothing. "Increased CSAT from 71 to 84 over two quarters by rewriting the escalation playbook" is the same idea with evidence attached. The second version reads as senior; the first reads as junior, even if the candidate has fifteen years of experience.

The second most common mistake is missing context. A bullet that says "managed budget" sounds the same whether the budget was $5k or $5M. Always include the scope: team size, budget, region, system, or customer count. Numbers are credibility.

Third: paragraph-shaped summaries at the top of the resume that read like a cover letter. Replace with a three-line career summary (role, years, top three skills) or remove it entirely. Recruiters skip prose.
