The first pass on your resume takes about seven seconds. In that window a recruiter looks at four things: your current title, your current company, your most recent dates, and your top skills block.
Skipped almost always: objective statements, references available on request, full postal addresses, high school details once you have a degree, and hobby lists with no relevance to the role.
Skimmed but scored: education, certifications, and tenure gaps. These are checks, not reads — make them scannable, not eloquent.
Read closely only if the first pass survives: your top two bullets under the most recent role. Put your best quantified achievement there and nowhere else.
Length: one page under ten years of experience, two pages beyond it. A third page is only defensible for academic CVs and publication lists.
Every line you cut makes the surviving lines more likely to be read. Delete anything a recruiter cannot act on.
