Listing duties instead of achievements
The most common and most costly mistake is describing what your job was instead of what you accomplished. "Responsible for managing the sales pipeline" tells a recruiter your title, not your value. Everyone with your title could write the same line.
Fix it by rewriting each bullet as an achievement with a result: "Managed a $2M pipeline and closed 118% of quota in 2024." Lead with an action verb, add a number, and show outcome. This single change lifts the quality of a resume more than any other.
Typos, tense slips, and inconsistency
A resume is a document you had unlimited time to perfect, so errors read as carelessness — a fatal signal for any role that values attention to detail. Recruiters routinely cut resumes for a single obvious typo when the pile is deep.
Beyond spelling, watch consistency: verb tense (past for old roles, present for current), punctuation at the end of bullets, date formats, and spacing. Read it aloud, then have someone else check it — you cannot reliably proofread your own writing.
Check the details people fumble under stress: your own phone number, your email address, and the company name if you accidentally left the last application’s name in the file.
ATS-breaking formatting
Elaborate templates — multi-column layouts, text boxes, tables, graphics, headers and footers — look impressive and frequently scramble the moment an ATS parses them. Your experience can land in the wrong field or vanish, and you never know it happened.
Keep it single-column with standard headings and a text-based PDF export. A clean, simple resume that parses perfectly beats a designed one that the software cannot read. Save the visual flair for portfolios and design roles that request it.
One generic resume for every job
Sending the same untailored resume to every posting is a volume strategy that quietly fails. It matches fewer of each job’s keywords, so it ranks lower in the ATS, and the recruiter does not see their specific requirements reflected back.
Keep a master resume and tailor a copy for each application: reorder bullets by relevance and mirror the posting’s key terms where they are genuinely true of you. Ten focused applications beat fifty generic ones.
Vague claims and clichés
Phrases like "hard worker," "team player," "detail-oriented," and "results-driven" are on nearly every resume, which is exactly why they carry no weight. They assert traits without proving them, and recruiters read straight past them.
Replace assertions with evidence. Do not say you are a leader — show "led a cross-functional team of 9 to ship on a compressed timeline." Do not claim you are detail-oriented — let a clean, error-free resume prove it. Demonstration always beats declaration.
The small stuff that still sinks you
A few smaller mistakes show up constantly and are trivial to fix.
- An unprofessional email address — use a simple firstname.lastname format.
- Including a photo, age, or marital status — unnecessary and, in many markets, a screening liability.
- "References available upon request" — assumed; delete it and reclaim the space.
- An outdated objective statement — replace with a targeted summary.
- Irrelevant hobbies padding the page — cut unless they genuinely support the role.
- Dense walls of text — use concise, one-to-two-line bullets with white space.
