10 Resume Mistakes That Are Quietly Killing Your Chances

A hiring manager I know — she runs talent acquisition at a logistics company, screens somewhere between 80 and 120 resumes a week — told me something that's stuck with me.

"Most of the people I reject," she said, "could probably do the job. I just can't tell from their resume."

I've been thinking about that for a year. It means the problem isn't usually the candidate. It's the document. And the document is failing for reasons the candidate doesn't see, because nobody ever explained how a resume actually gets read.

So let me explain it. Then let me show you the ten specific ways I've watched good candidates eliminate themselves before anyone picked up the phone.

1. Writing job descriptions instead of accomplishments

This is the most common mistake by a wide margin, and I covered it in an earlier post, but I'm putting it first here because if you fix nothing else, fix this.

"Responsible for managing social media accounts" describes a job. "Grew LinkedIn following from 800 to 14,000 in 11 months, with posts averaging 6x the engagement of the company's previous content" describes a person.

The difference isn't about sounding impressive. It's about giving the reader something to evaluate. Job descriptions tell them what the role was. Accomplishments tell them what you actually did with it.

I spoke to a recruiter at a tech company last year who told me she spends about eight seconds on initial screen. Eight seconds. In eight seconds she can read your name, your current title, and maybe two bullet points. If those two bullet points describe responsibilities, she has learned nothing about you. If they describe results, she has a reason to keep reading.

Fix: For every bullet point, ask yourself — if someone else had held this exact role, could they have written this same sentence? If yes, it's a job description. Rewrite it until the answer is no.

2. A generic objective statement at the top

"Seeking a challenging position in a dynamic organization where I can leverage my skills to contribute to team success."

I have read this sentence, in various forms, hundreds of times. It says nothing. It describes no one specifically. It could be on the resume of a 22-year-old fresh out of college or a 45-year-old VP stepping down to try something new.

Objective statements peaked in the 1990s. They're outdated for a simple reason: they're about what you want, and the hiring manager doesn't care what you want. She cares what she needs.

What belongs at the top of your resume instead is a summary — three to four lines that answer the only question the reader has: why should I keep reading? It should say who you are, what you're good at, and ideally give one specific number or fact that makes you credible.

Bad: "Marketing professional with 6 years of experience seeking to grow in a collaborative environment."

Better: "Performance marketer with 6 years in B2C e-commerce. Managed up to $800K in monthly ad spend; last role, cut cost-per-acquisition by 34% over 18 months while scaling revenue 2.4x. Strongest in paid social and retention."

Same person. Completely different first impression.

3. One resume for every job

I understand why people do this. Customizing a resume for every application takes time, and when you're sending out fifteen applications a week, it starts to feel like an impossible ask.

But here's the math: most ATS systems — the software that screens your resume before a human sees it — score applications partly based on keyword overlap with the job posting. If the posting says "cross-functional collaboration" and your resume says "worked with multiple teams," a system might count those as different things. If they want "Python" and you wrote "programming," same problem.

Beyond the ATS, there's a human version of the same issue. A resume written for a general audience reads like it was written for no one in particular. A resume that uses the exact language from the job posting, and puts the most relevant experience first, reads like you actually want this specific job.

The fix doesn't have to be a full rewrite every time. Keep a master version with everything in it. When you apply somewhere, duplicate it and spend 20 minutes: update the summary to match the role, reorder bullets so the most relevant work appears first, and check that your language mirrors theirs. Twenty minutes. That's the whole job.

4. Burying the most important information

A lot of people structure their resume the way they'd tell a story — chronologically, building to the present. The assumption is that the reader will follow along and arrive at your current, most impressive work at the end.

The reader is not following along. She's scanning. And she's probably starting somewhere in the middle.

Put your strongest material first. Not first chronologically — first in terms of relevance to the job you're applying for. If your most impressive accomplishment is from three years ago at a different company, it might belong higher on the page than your current role.

Within each job, same principle. The bullet that best answers "why should I hire this person" goes at the top. The stuff that supports it comes after. Lots of people do it the other way — they build up to the impressive thing like they're writing a mystery novel. By the time the reader gets there, she's already moved on.

5. Soft skills in a vacuum

"Strong communicator. Team player. Detail-oriented."

These three phrases appear on, conservatively, 70% of resumes. They mean nothing in isolation because everyone claims them and they can't be verified from a resume. You can say you're a strong communicator; I have no reason to believe you over the other 40 people who said the same thing this week.

The fix is to show the skill through a result rather than claim it as a trait.

Not "strong communicator" — but "presented quarterly results to a board of 12; converted two skeptical members to approve a budget increase." Not "detail-oriented" — but "audited 3 years of vendor contracts and found $180K in billing errors that were subsequently recovered."

If you did something that required the skill, describe what you did. The skill is implied. Claiming the skill without evidence is just noise.

6. A photo (in most countries, for most jobs)

This one surprises people. But in the US, UK, Canada, and Australia, putting a photo on your resume is actively discouraged — not just unnecessary, but potentially a flag.

The reason is straightforward: a photo introduces information that has nothing to do with your ability to do the job, and most large companies have legal reasons to avoid knowing it before they interview you. Age, race, perceived gender — none of that should factor into a hiring decision, and a photo makes it impossible to pretend it didn't enter the room.

Some recruiters have told me they'll pass on a resume with a photo not because of bias but because it signals the candidate doesn't know the norms of the market they're applying into. In some European countries and in much of East Asia, photos are still expected. Know the convention for your specific market and follow it. Don't follow conventions from a different country's resume guide.

7. The wrong length — usually too long, sometimes too short

I've seen this go both ways.

The too-long version: someone with eight years of experience and a four-page resume because they included every project, every responsibility, every tool they've ever touched. I once received a resume from a candidate who had three separate bullet points about Microsoft Office. Three.

The too-short version: someone with twelve years of experience who was so worried about length that they compressed everything into eight bullets spread across a page and a half, with the result that major accomplishments were reduced to single-line summaries that told me almost nothing.

The actual rule: one page if you have fewer than ten years of experience. Two pages if you have more, and only if both pages are earning their place. "Two pages" is not a goal to hit — it's a ceiling to stay under.

If you're going over one page, the question to ask is not "what can I add?" but "what actually matters to this specific reader?" Most of the time, you'll find a third of your content is padding that exists because it was hard to cut, not because it should be there.

8. Unexplained gaps

A gap year. A layoff. A health thing. A parent who needed care. Life happens, and more hiring managers than you'd think have been through their own version of it.

The mistake isn't having a gap. The mistake is leaving it unexplained and hoping no one notices.

They notice. The gap sits there on the page and the reader fills it with their imagination, which is usually worse than the truth. "2020–2022: left role to provide full-time care for a family member" is a complete explanation that takes eleven words and neutralizes the question entirely. "Took a year to travel and reassess career direction" — also fine. "Completed freelance projects in [field] while exploring next opportunity" — even better if it's true.

What you don't want is the reader sitting with an unexplained two-year hole and wondering what happened. They won't ask you about it in a first screen. They'll just move on.

9. Typos and inconsistent formatting

This one shouldn't need to be here. And yet.

A typo in a resume does something specific to a reader's brain: it makes her wonder what else you didn't catch. If you missed this, what else? It's not a rational calculation — it's a reflex. A single typo in the wrong place can undo three strong accomplishments above it.

Formatting inconsistencies do the same thing at a slower pace. Dates in different formats on different jobs (January 2021 vs. 2021/01 vs. Jan '21). Bullet points that are sometimes dashes, sometimes dots, sometimes nothing. Inconsistent capitalization of job titles. None of this is catastrophic alone. Together it gives the impression of someone who doesn't notice details, which is a bad impression to give before you've said a word.

Fix: after you're done writing, read the whole document once for content and once specifically for formatting. Not at the same time. Separately. Your brain will catch different things each pass.

Then have someone else read it. Not to give you compliments — to catch what you can't see because you wrote it.

10. Trusting advice from the wrong era

This is the mistake underneath several of the other mistakes, so I'm saving it for last.

A lot of people learn how to write a resume from a career services office visit in college, a book they found at a library, a parent who last applied for a job in 2003, or a well-meaning LinkedIn post that got traction because it sounded authoritative. Some of that advice is fine. Some of it is actively outdated.

Objective statements: outdated. References available upon request: outdated, and also takes up a full line of your page for something every reader already assumes. Listing your GPA unless you graduated in the last two years and it's above 3.7: usually outdated. Functional resume format (skills-based, hiding chronology): almost always a red flag to modern recruiters, who have learned to associate it with candidates who are trying to hide something.

The job market shifts. ATS systems have changed how resumes get filtered. Remote work has changed how companies think about location. The past three years changed how companies think about gaps. If your resume advice is more than five years old, some of it probably doesn't apply anymore.

The best source I'd point you to is actual current job postings in your field. Fifteen of them. Read what they're asking for, how they describe the role, what language they use. Then make sure your resume sounds like someone who exists in the same world as those postings.

My hiring manager friend — the one who screens 80 to 120 resumes a week — told me something else when we talked. She said the resumes she remembers, the ones she passes up the chain, are almost never the most credential-heavy ones.

They're the ones where she can tell, in 30 seconds, that the person on the other side of the document understood exactly what she needed and took the time to show her they had it.

That's it. That's the whole game. The ten mistakes above are ten different ways of failing to do that one thing.

Most of them are fixable in an afternoon.
