5 Resume Mistakes That Are Costing You Interviews

1. Sending the Same Resume to Every Job

A generic resume is optimized for no one. ATS systems rank resumes against specific job descriptions — a resume that doesn't mirror the posting's language will score lower than a less-experienced candidate who tailored theirs.

You don't need to rewrite your resume from scratch for every application. The fix is targeted: update your professional summary and skills section to reflect the specific role, and adjust 1–2 bullet points under your most recent job to match the posting's priorities. That's often enough to move from an 40% keyword match to a 75%+ match.

The fix

Keep a “master resume” with all your experience. For each application, copy it and tailor the summary and top bullet points to the job description. Save the tailored version separately.

2. Listing Duties Instead of Results

A job description tells employers what you were supposed to do. A resume should tell them what you actually did — and how well. Most bullet points read like job descriptions, which makes candidates interchangeable.

Compare these:

• Responsible for managing social media accounts across platforms.
• Grew LinkedIn following from 2,000 to 14,000 in 8 months by launching a weekly industry analysis series, driving a 35% increase in inbound leads.

The second version shows the same responsibility, but with evidence. Every recruiter reading it knows immediately what this person is capable of — and it's memorable in a way the first version isn't.

The fix

For each bullet point, ask: “So what?” If your answer includes a number, a time frame, or a business outcome, add it. If you can't quantify something precisely, use relative language: “reduced churn significantly,” “cut review cycle in half,” “largest client in the region.”

3. Overcrowding or Over-Designing the Page

Two things happen with bad formatting: ATS can't parse it, and recruiters can't skim it. Either way, your content gets ignored.

Over-designed resumes (multiple columns, infographic elements, icons for skill ratings, tables) look impressive as PDFs but disintegrate inside ATS software. The parser extracts text linearly — what comes out is often garbled.

Overcrowded resumes — tiny margins, 9pt font, 15 bullet points per job — make it hard for a recruiter doing a first-pass scan to find anything. If nothing stands out, the resume gets passed over.

The fix

Single column. 10–11pt font. 0.75–1 inch margins. No more than 5–6 bullets per job. Use white space deliberately — it helps recruiters navigate. If you're over one page, cut older or less relevant experience rather than shrinking the font.

4. Including Outdated or Irrelevant Information

Several resume conventions that used to be standard are now either neutral at best or actively harmful:

• Objective statements. Replace with a professional summary focused on what you offer, not what you want.
• “References available upon request.” Everyone knows. It wastes a line. Cut it.
• High school education when you have a college degree. Remove it.
• Jobs from 15+ years ago.Unless they're directly relevant, cut anything past the 10-year mark.
• Hobbies and personal interests— unless they're directly relevant to the role or demonstrate a relevant skill.
• A photo. In most countries and industries, photos invite unconscious bias and offer nothing useful to the recruiter.

The fix

Every line on your resume should earn its space. If it doesn't increase your chances of getting the interview, it's taking space from something that would.

5. Typos, Inconsistency, and Passive Language

Typos are resume killers — especially in roles that require written communication, attention to detail, or any kind of client-facing work. Spellcheck catches misspellings, but not the wrong word spelled correctly (“lead” vs “led,” “their” vs “there”).

Inconsistency is subtler but just as damaging. Mixed date formats (Jan 2022 vs 01/2022), inconsistent punctuation (some bullets end in periods, some don't), and shifting verb tenses (past tense for current roles) all signal carelessness.

Passive language weakens your bullet points. “Was responsible for” and “helped with” hide your actual contribution. Lead with strong action verbs: built, launched, reduced, led, negotiated, designed, automated.

The fix

Read your resume aloud. Read it backwards (forces you to see each word individually). Have someone else read it. Check: are all dates in the same format? Does every bullet start with a past-tense action verb (except your current role)? Is punctuation consistent throughout?
