The resume mistakes that actually cost you interviews

Format mistakes ATS parsers punish

Multi-column layouts read out of order or not at all. Text in headers/footers is skipped by many parsers — contact info there can vanish. Tables, text boxes and graphics scramble parsing. Image-based or “flattened” PDFs contain no readable text at all. Single column, real text, standard headings avoids all of it.

Vague bullets

“Responsible for managing social media” says what the job was; “Grew Instagram from 2k to 40k followers in 8 months” says what you did with it. Every bullet without a number, artifact or concrete outcome is a wasted line — and weak openers like “helped with” or “worked on” read as filler.

One resume for every job

The highest-leverage fix: postings keyword-screen, and a resume tuned for one role scores poorly against another. You don’t need a rewrite per application — swap the summary and the skills emphasis to mirror each posting’s actual vocabulary.

Length and priority errors

Two pages before ten years of experience, first-person pronouns, an “objective” statement, high-school details past your first year of college, “references available upon request” — all signal you don’t know what matters. One page, strongest material in the top third.

Honesty mistakes

Inflated titles, stretched dates and invented metrics surface in background checks and reference calls — usually after you’ve counted on the offer. If you don’t know the exact number, describe the concrete thing you delivered instead of inventing one.

Check before you send

Run your resume and the posting through our free ATS checker: it shows your match score, missing keywords, and format warnings — the same checks in this list, automated. It runs in your browser; your resume never leaves your machine.

Contact-block mistakes

An unprofessional email address, a dead LinkedIn link, a missing location when the posting is location-bound, or contact info buried in a header the parser skips. Name, one email, one phone, city + state, one profile link — in the body of the page, as real text.

Typos cluster where you stopped proofreading

The classic misses: your own job titles, company names, the months in date ranges, and the last section you edited. Read the resume bottom-up once — it defeats the skimming that hides errors — and have one other person read it cold.

Inconsistent formatting reads as carelessness

Three date formats, two bullet styles, headings that switch case, one role bolded and the next not — each is minor, together they say “didn’t check”. Pick one convention for dates, bullets and headings and let a builder enforce it mechanically.

Stale or padded skills

Software nobody has asked about in a decade, “Microsoft Word” for an engineering role, skill bars rating yourself 4/5 at things — and the opposite failure: listing skills you’d fail a five-minute question on. List what the posting names and what you can defend.

Sending the wrong file

A file named “resume_final_v7 (2).pdf”, a DOCX when the portal asks for PDF, an export where the second page starts mid-bullet. Name it “Firstname-Lastname-Resume.pdf”, match the requested format, and open the exported file once before uploading it.

The pre-send pass, in order

Parse check (ATS checker) → keyword match against this posting → bullets quantified and one idea each → dates consistent → contact block correct → filename professional → exported file opened and eyeballed. Seven checks, five minutes, most rejections avoided.
