We review a lot of resumes at Workplacea, and the same problems appear over and over, regardless of industry or seniority. The encouraging part: the most common resume mistakes are not subtle failures of talent, they are fixable mechanical and judgment errors, and most take minutes to correct once you can see them. Here are the seventeen we encounter most, grouped by type, each with its fix.
Content mistakes: the words themselves
1. Listing duties instead of achievements. "Responsible for social media accounts" describes the job; it fits every person who ever held it. The fix is the achievement pattern: verb, scope, outcome. "Ran Instagram for a 12-location gym chain, growing followers from 8k to 31k in 14 months." The full formula, with dozens of rewrites, is in our guide to resume bullet points.
2. No numbers anywhere. A resume with zero quantities forces the reader to guess your scale: a team of two or forty, a budget of thousands or millions? Every job contains countable things: volume, frequency, money, people, time. Honest estimates ("about 50 orders a day") beat blank adjectives.
3. Buzzword soup. Results-driven, synergy, go-getter, dynamic self-starter. These phrases are claims without evidence, and readers skim straight past them. Replace each adjective with the fact that earned it; the full replacement pattern lives in resume buzzwords to avoid.
4. A summary that says nothing. "Motivated professional seeking a challenging opportunity" spends the most-read lines on the page on air. Write scope, one proof point, and direction, or cut the section entirely.
Formatting mistakes: how it sits on the page
5. Walls of text. Five-line paragraphs under each job title guarantee skimming. Convert prose to bullets, three to six per recent role, each two lines or fewer.
6. Tiny fonts and vanished margins. Nine-point type and 0.3-inch margins are how a two-page resume impersonates a one-pager. Readers notice the crowding before they read a word. Cut content instead; the priority order for trimming is in our resume length guide.
7. Chaotic dates. "2021-23," "March 2024," and "6/2025" on one page make a careful reader wonder what else is inconsistent. Pick one format, include months, and apply it everywhere, including a consistent treatment of "Present."
8. Design doing the talking. Skill bars rating your Excel at four dots, three accent colors, portrait photos, and infographic timelines. Decoration crowds out evidence and often breaks text extraction. One font, one accent color at most, and the creativity goes into the bullets.
Targeting mistakes: right resume, wrong reader
9. One generic resume for every application. Untailored applications compete against candidates who mirrored the posting's language and led with the matching evidence. You do not need a rewrite per job, just a fifteen-minute pass: reorder skills, swap two bullets, adjust the summary to the posting's vocabulary where it is true of you.
10. Burying the relevant material. The bullet that matches the job sits fourth under a role on page two, because you ordered bullets by personal pride rather than reader interest. Lead every role with the line most relevant to this application, and let the impressive-but-irrelevant material move down or out.
Honesty mistakes: the ones that end processes
11. Inflated titles. Upgrading "coordinator" to "manager" feels harmless until a background check or a reference call surfaces the real title, at which point the whole document loses its credibility. If your official title undersold the work, use the honest fix: real title, then a parenthetical scope note, like "Marketing Coordinator (sole marketer for a 40-person company)."
12. Stretched dates. Extending an end date to cover a gap is the most discoverable lie in hiring, since dates are exactly what employment verification checks. Gaps handled plainly (one line, matter-of-fact) cost far less than a caught adjustment costs.
Parsing mistakes: what the software sees
Most large employers run applications through an applicant tracking system that extracts your resume into structured fields before a recruiter reads it. Three layout habits regularly damage that extraction; none of them "auto-reject" you, but all of them can degrade what the recruiter sees, and our ATS resume guide covers the mechanics without the myths.
13. Load-bearing tables and text boxes. Content inside layout tables and floating text boxes can extract out of order or not at all. Keep structure in plain text: headings, lines, bullets.
14. Contact details in the document's header region. Some extractors skip Word's header and footer areas entirely, which is a bad place to lose your phone number. Put contact details in the body of page one.
15. Text that is actually a picture. Rasterized name banners, icon fonts standing in for "email," skill graphics, and scanned PDFs all extract as nothing. If you cannot select it as text in your PDF viewer, hiring software cannot read it either.
Proofreading mistakes: the last-mile fumbles
16. Typos, and especially typos in contact details. A misspelled word costs credibility; a mistyped phone number or email costs the interview itself, silently. Proofread contact details character by character, and send yourself a test email from the address as written on the page.
17. Stale artifacts. The 2024 date still in the header from your last search, a dead portfolio link, a LinkedIn URL pointing at the digits-string default, an objective naming a different company. Each one tells the reader this document was not prepared for them.
A proofreading system that actually catches errors
Willpower is not a proofreading method. This sequence is:
- Let it rest. Even a few hours between writing and proofing resets your eyes; overnight is better.
- Read it aloud, slowly. Your ear catches dropped words and mangled grammar your eye autocorrects.
- Read it backward, bullet by bullet, from the bottom of the page up. Stripping the narrative flow exposes each line as it actually is.
- Do a dedicated facts pass: every date, every number, every name, the phone number, the email, each link clicked.
- Change the view. Print it, or export the PDF to your phone; new rendering, new eyes.
- Recruit one human who will read it cold and mark anything they stumbled on.
- Run a parse check so the software-facing errors get the same scrutiny as the human-facing ones; the free ATS resume checker shows you the extracted result next to your original.

- One date format everywhere, months included
- No skill bars, photos, or decorative graphics carrying real information
- Skills and summary echo this posting's actual language
- The most relevant bullet sits first under each role
- Every title and date matches what verification would return

- Contact details verified character by character; links clicked today
- One other human has read the final version
Seventeen checks for seventeen mistakes. If your draft fails several and you would rather rebuild than patch, our step-by-step resume guide walks the whole construction from raw material to final proof.
Frequently asked questions
What is the most common resume mistake?
Duties instead of achievements, by a wide margin. It is also the most expensive, because it wastes the resume's core real estate saying things every other applicant can also say.
Can one typo really cost me an interview?
Sometimes, particularly in detail-heavy fields where the resume doubles as a work sample. But the reliably fatal version is rarer and quieter: a typo in your email address or phone number, which costs you the callback without anyone deciding anything.
Are resume mistakes worse for senior candidates?
The standard rises with seniority. A cluttered page from a student reads as inexperience; the same page from a director candidate reads as a signal about their communication and judgment.
How do I know if my resume has parsing problems?
Test it instead of guessing: run the file through a parser-based checker and compare the extracted fields against your original. If your name, contact details, jobs, and dates all land correctly, you are clear of the entire parsing category above.
Fix the fixable before anyone else sees it
Every mistake on this list is visible to a tool before it is visible to a recruiter. Run your resume through Workplacea's free resume checker and get the content, formatting, and parsing problems flagged in one pass, with the honest reasoning behind each flag, then repair them in the editor where the fixes stay fixed.
