The Resume Sections Most People Get Wrong (and How to Fix Each One)

Most resumes are not bad. They are quietly wrong in a few specific places that cost interviews without the candidate ever knowing why. Here is a section-by-section walk through the most common mistakes, and the fix for each.

The mistake: A vague, adjective-heavy paragraph. "Results-driven professional with a passion for excellence" tells a recruiter nothing and wastes the most valuable real estate on the page.

The fix: Make the first line state who you are and the level you operate at, concretely. "Senior backend engineer, 8 years building payment systems at scale" does more in nine words than three sentences of adjectives. The summary is the one place a recruiter decides whether to keep reading, so it has to position you for the role you want, not describe the one you had.

The mistake: Bullets that describe duties instead of results. "Responsible for managing the team" is a job description, not an achievement. It is also the single most common reason strong candidates read as average.

The fix: Lead with the outcome and quantify it. "Cut deployment time 40% by rebuilding the CI pipeline" beats "responsible for CI". Every bullet should answer "so what?" with a number where one exists. If a bullet has no result and no number, it is probably filler.

The mistake: A long, undifferentiated list that mixes "leadership" and "Microsoft Word" with the hard skills that actually matter, so the important ones get lost.

The fix: Lead with the hard, role-relevant skills and tools. These are what an ATS matches against the job description and what a technical screener scans for. Drop the obvious filler (everyone can use email). If the role names specific technologies, make sure the exact terms appear here. This is where tailoring to the job description pays off most.

The mistake: Inconsistent formatting and, for experienced candidates, too much space given to a degree from years ago.

The fix: Keep it to degree, institution, and dates, formatted exactly like every other section. If you have more than a few years of experience, education moves to the bottom and shrinks. For early-career candidates, it stays near the top and can carry relevant coursework or honours.

The mistake: Either omitting them when they would carry weight (early-career, career switchers) or padding them with irrelevant filler.

The fix: Include projects and certifications that are directly relevant to the target role, framed with the same outcome-and-number discipline as work experience. For a career switcher, a strong, relevant project can do more than a decade of unrelated work history. Browse resume examples to see how this is done well by role.

The mistake: Mixed date formats, inconsistent spacing, a typo in a job title or company name, or a creative layout that an ATS cannot parse.

The fix: Pick one format for everything and hold it. Use a clean, single-column, ATS-tested layout. Proofread the proper nouns especially, since a typo in a company name reads as carelessness. If you are not sure your layout parses, start from a template built to pass tracking systems.

Every section above maps to a dimension a tracking system scores. The fastest way to find which of your sections are quietly costing you is to run the resume through the free ATS checker. It scores each section, tells you which ones fail, and gives you the fixes in priority order, with no signup.

You rarely need a new resume. You need to fix the same handful of sections most people get wrong: a vague summary, duty-based bullets, a cluttered skills list, and inconsistent formatting. Fix those, section by section, and an average-looking resume becomes a shortlisted one.
