10 resume mistakes that quietly cost you interviews
5 min read
Most resume advice covers spelling and consistent tenses. Those matter, but they are rarely the reason a strong candidate is passed over. These are the failures that do real damage, in rough order of how much they cost.
1. Listing duties instead of achievements
'Responsible for managing the social media calendar' tells the reader what the job was, not whether you were good at it. Anyone with that title could write the same line.
Fix: end every bullet with a result. What changed because you did it - a number, a launch, a reduction, an adoption figure.
2. No numbers anywhere
Numbers are how a stranger calibrates your claims. A resume with no figures reads as unverifiable, however impressive the roles.
Fix: quantify scale even where impact is hard to measure - team size, budget, users, volume, frequency, time saved.
3. Sending the same resume everywhere
A generic resume is optimised for no one. It will match fewer of the terms recruiters search, and it reads as untargeted.
Fix: keep a master copy and cut it down per application, mirroring the posting's language where it honestly applies.
4. A two-column layout
Sidebars look organised to you and often arrive scrambled in an applicant tracking system, which may read straight across both columns.
Fix: a single column. You lose nothing visually that good typography cannot replace.
5. Burying recent, relevant work
Reverse-chronological order exists because recency predicts relevance. Leading with an unrelated early role, or with education years after graduating, spends your best space badly.
Fix: most relevant and most recent first, both between sections and between bullets inside a role.
6. Skills sections that list the obvious
Microsoft Word, email and 'the internet' are assumed. Listing them suggests you had trouble filling the section.
Fix: list only skills someone could plausibly not have, and that the job actually asks for.
7. Dense, unbroken blocks of text
A first pass over a resume is a scan, not a read. Paragraphs get skipped entirely.
Fix: short bullets, one idea each, ideally under two lines.
8. Unexplained gaps and vague dates
Removing dates to hide a gap reads as evasive and makes your history hard to follow - which is worse than the gap.
Fix: keep clear month-year ranges and, where useful, name the gap plainly. Career break, study, caring responsibilities. It is far more common than people assume.
9. A file that cannot be parsed
A beautifully designed resume exported as an image is invisible to screening software, and so are headers, footers and text boxes.
Fix: export a text-based PDF, then copy the text out of it to confirm everything survives.
10. Being modest
Under-claiming is as costly as over-claiming, and much more common. If you led something, write led. If you shipped it, write shipped.
Fix: describe your actual contribution in the strongest accurate verb available - accurate being the constraint that matters.
