Seven resume mistakes that stop applications before a human reads them, with before-and-after rewrites and a 30-minute…
Quick answer: Most resumes are rejected for seven reasons: listing duties instead of results, sending the same version everywhere, formatting screening software cannot read, an empty objective line, confusing dates, too much text, and small errors in the file name or contact details. All seven are fixable in one sitting.↗ Share on X

Most resumes get rejected for seven reasons, and none of them are about talent. They are: describing duties instead of results, sending the same version to every job, formatting the screening software cannot read, an opening line that says nothing, confusing dates, a wall of text, and small errors in the file name or contact details.

Each one below has the fix, and most have a before and after you can copy. Work through them in order and give yourself about thirty minutes.

1. You listed duties instead of results

This is the big one. A job description says what you were supposed to do. A resume should say what actually happened because you were there.

You do not need a big number for every line. "So that" is enough. Write what you did, then write what changed because of it.

Fast fix: take every bullet that starts with "Responsible for" and rewrite it to start with an action verb: built, cut, trained, fixed, launched, organized, recovered.

2. You sent the same resume everywhere

The same file, sent to forty jobs, matches none of them well. Screening software and human readers both look for the words used in the job ad, and a resume that never uses them looks like a poor fit even when it is not.

The fix, in four steps:

1. Paste the job ad into a blank document.

2. Mark every skill, tool and qualification it names more than once.

3. Check which of those you genuinely have.

4. Make sure each one you have appears in your resume, in the words the ad used.

If the ad says "accounts payable" and your resume says "supplier payments", add the phrase from the ad. Never claim a skill you do not have. The interview will find it.

3. The screening software cannot read your layout

Most medium and large employers run resumes through software first. It reads text. It struggles with everything else.

Avoid thisUse this instead
Text inside a text box or a graphicPlain text on the page
Two- or three-column layoutsA single column, top to bottom
Contact details in the header or footerContact details in the body, at the top
Tables to arrange your work historySimple headings and bullet points
Icons or symbols instead of labelsThe words Phone, Email, Location
A scanned image or a photo of the resumeA real text document

Send a PDF unless the ad asks for something else, and make one check first: open the PDF, select all, copy, and paste it into a blank document. If the result is jumbled or empty, the software will see the same mess.

4. Your opening line says nothing

"Seeking a challenging position in a dynamic company where I can grow." Everyone writes this, it describes nobody, and it takes the most valuable space on the page.

Replace it with two or three lines that answer one question: what are you, and what do you bring?

Name the role, the years, one or two specific strengths, and what you are looking for. If you are changing careers, use the space to connect what you did to what you want.

5. Your dates are confusing

Readers scan dates before they read anything else. Anything unclear reads as something hidden, even when there is nothing to hide.

A gap is normal. An unexplained gap invites guessing, and guessing rarely goes your way.

6. It is too long and too dense

A reader skims first and reads second. If everything is the same size and packed edge to edge, there is nothing to skim.

The rules that fix this:

1. One page for under ten years of experience. Two pages after that. Three only in academic or medical fields where a longer record is expected.

2. Three to five bullets per job, and fewer for older roles.

3. One line per bullet. Two if it really earns it.

4. Cut jobs older than about fifteen years, or list them as one line with no detail.

5. Leave white space. Margins of at least two centimeters, a blank line between sections.

6. One clear font, sized 10 to 12 for the body.

Delete the "References available on request" line. It is assumed, and it costs you a line.

7. Small errors nobody told you about

These are the cheapest to fix and the most expensive to leave.

ProblemWhat to do
File named resume_final_v3.pdfRename it Firstname-Lastname-Resume.pdf
An email address like partyanimal99Create a plain one with your name
Phone number with a missing digitRead it out loud, digit by digit
Different tenses in the same jobPast jobs in past tense, current job in present
Typos in the company or role nameCheck the spelling against the ad itself
A link to a profile that is out of dateUpdate the profile or remove the link

Read the resume backwards, bottom to top, to proofread it. It breaks the meaning and leaves only the words, which is the only way most of us catch our own typos.

The 30-minute fix routine

1. Minutes 0 to 5. Fix the file name, the email address and the phone number. Done forever.

2. Minutes 5 to 15. Rewrite every "Responsible for" bullet into an action and a result.

3. Minutes 15 to 20. Replace the objective line with the two-line summary from section 4.

4. Minutes 20 to 25. Open the job ad, mark the repeated words, and make sure the ones you honestly have appear on the page.

5. Minutes 25 to 30. Copy the PDF text into a blank document and check it reads in order. Then read the whole thing backwards.

How do you know it worked?

You will not get feedback from most applications, so use checks you control:

Your next step today

Open your resume and go to the most recent job. Rewrite the first bullet so it names something that changed because you were there, not something you were supposed to do.

One bullet. Then save the file under your own name, and do the next one tomorrow. A resume rewritten one line at a time gets finished. One rewritten from scratch usually does not.

FAQ

How long should a resume be?

One page for under about ten years of experience, and two pages beyond that. Longer records are normal in academic, research and medical fields. The limit exists because readers skim, so extra pages of detail usually reduce what gets read, not increase it.

Should I send a PDF or a Word file?

Send a PDF unless the job ad asks for something else, because a PDF keeps the layout the same on every screen. Check it first by selecting all the text, copying it, and pasting it into a blank document. If it comes out jumbled, rebuild it in a single-column layout.

What should I do about a gap in my work history?

Name it in one short line where it happened: caregiving, study, illness, redundancy, travel. A stated gap reads as a normal life event. An unexplained one makes the reader guess, and guessing rarely works in your favor.
