Top 7 Resume Mistakes and How AI Can Help You Avoid Them

Sadiah Haque

Imagine a recruiter, juggling dozens of applications, landing on your resume. You’re hopeful, but a small mistake, typo, or irrelevant information silently kills that promising prospect. Resumes are your professional handshake, and AI tools can be your silent partner in making sure that handshake is strong, confident, and error-free.

7 Resume Mistakes Everyone Makes

Below, we’ll explore the most common resume mistakes across industries and how AI can help transform resumes into polished, compelling documents that easily capture attention and pass automated filters.

1. Typos and Grammar Mistakes: The Credibility Killers

A single typo will often cost you a job. It may seem harsh, but for recruiters who have to narrow down dozens of applicants, errors signal carelessness. Imagine a software engineer applying for a position with a glaring misspelling of “JavaScript” or an HR professional listing “attention to detial.” These mistakes are more than cosmetic—they erode credibility.

Grammar-checking add-ons like Grammarly or resume formatting tools like Allsorter go way beyond simple spell check. They detect inconsistencies, suggest fixes, and even assess tone. For example, they can flag whether your phrasing is too passive or if your language is overly verbose, helping you make a concise yet professional-sounding tone.

Pro Tip: Don’t let AI do all the heavy lifting. As good as these tools are in catching technical errors, a second pair of human eyes will help your resume reflect your personality and voice.

2. Poor Formatting: When Looks Really Do Matter

Think of a resume with mismatched fonts, awkward spacing, or sections randomly placed. Poor formatting disrupts the reader's flow, making them work harder to understand your message. To make it even worse, it often trips up the applicant tracking systems, which rely on clean, logical structures to parse information.

Design tools like Canva offer professionally designed templates that emphasize clarity and structure. And if you’re thinking of a one-click solution, you’ve got Allsorter’s resume formatting that ensures uniformity in font sizes, bullet alignment, and spacing, making your resume visually appealing.

Allsorter’s platform is also ATS-friendly, increasing the likelihood your application makes it past the first hurdle.

3. Irrelevant Content: Telling Stories That Don’t Matter

Recruiters don’t need to know about your high school debate championship if you’re applying for a senior marketing position. Including irrelevant or outdated information clutters your resume and distracts from your core message. Every line of your resume should serve a purpose: to demonstrate your qualifications and value.

AI resume formatting solutions analyze job descriptions and compare them to your resume. They highlight irrelevant sections and suggest which key terms or qualifications you might emphasize.

If, for example, the job calls for "data analysis," and you had the forethought to bury it in some generic "problem-solving" header, AI would let you know to bring that right up to the forefront. One good exercise here is asking yourself, "Does this piece of information make me a stronger candidate for this job?" If not, it's better left out.

4. Generic Resumes: Failing to Tailor Your Story

Hiring managers can spot a generic resume a mile away. When every application receives the same boilerplate document, you’re missing an opportunity to connect with the specific needs of the employer. For example, a resume sent to a creative agency should look and feel different than one submitted for a corporate finance position.

AI-driven platforms like Allsorter help you create different versions of your resume, fitted for a particular job or industry. By analyzing keywords from job postings, they help you craft resumes that speak directly to the hiring manager's priorities. You can even create a branded resume that better reflects your personality, so you have a better chance of being noticed.

Pro Tip: Think of tailoring your resume like telling a different story to fit each job. Emphasize the chapters of your career that most closely align with the requirements of the role.

5. Overuse of Buzzwords: Saying a Lot Without Saying Much

How many times have you read resumes that tout the applicant as a "results-oriented team player"? Those words are spoken so much that they become void. Rather than employers being told what you are, it's best to show them.

Tools like Hemingway help crystallize your language to make certain it is clear and concise. They are able to identify vague buzzwords and suggest more specific action-oriented phrases. Instead of saying "team player," you could write, "Collaborated with cross-functional teams to launch a $2M product line, increasing sales by 15%."

6. Not Including Quantifiable Achievements: The Proof is in the Numbers

It's good to say that you "improved efficiency," but it's a whole lot better to say, "Increased workflow efficiency by 25%, saving the company $10,000 annually." Employers want to see proof of your results, not just statements of what you did.

Good AI formatting resume tools can nudge you toward quantifying your contributions. Example questions might be, "What measurable outcomes did you achieve in your last role?" or "How did your efforts save time or resources?

Pro Tip: Approach your resume as if it were a report card of results. Numbers and metrics add credibility and show, rather than tell, the tangible results of your work.

7. Neglecting ATS Optimization: Getting Lost in the Machine

Even the best resumes won't make it through to a human if they aren't ATS-friendly. These systems look for specific keywords and a clear structure. If your resume isn't optimized, it risks being filtered out.

To tackle this issue, Allsorter provides ATS compatibility analysis, helping you fit in the right keywords, format, and section headings that will make you noticeable to a recruiter. This way, you can rest assured that your resume will seamlessly go through any roadblock—whether human or AI.

How AI is Changing the Resume Landscape

The impact of AI has really hit home about writing and reviewing resumes. Beyond just correcting mistakes, it's innovating the way people are applying for jobs by providing real-time suggestions and personalized recommendations—all while saving time.

Improved Efficiency

AI isn't just helping individuals refine their resumes; it's actively changing how recruiters and hiring managers review candidates. For example, many companies now use AI to scan resumes for specific keywords and qualifications before they even reach a human recruiter.

This means job seekers not only have to craft resumes that resonate with human readers but also optimize them for algorithms. AI-powered resume tools like Allsorter are making this process much easier, matching your resume to precisely what the recruiters are looking for.

Inclusive Recruiting

Moreover, AI is fostering inclusivity by addressing biases that traditionally affected the hiring process. In manual reviews of resumes, unconscious biases can sometimes cloud decisions and lead to hiring inequities. AI-driven platforms aim to level this playing field by focusing on objective qualifications rather than subjective interpretations.

For example, some AI tools anonymize resumes by removing identifying details like names, genders, and photos before they are reviewed. This ensures that the initial screening is based purely on skills and experience, giving each applicant an equal opportunity. And as AI continues to advance, so does its capacity to give more power to job seekers.

Wrapping Up

Your resume is more than a list of jobs; it's your professional story. Mistakes, large or small, can obscure that story or shut it down entirely. Luckily, you can use AI to eliminate errors, optimize formatting, and tailor resumes for human and machine audiences.
