We are human and humans make mistakes but a professional resume is the first impression on potential employers, so avoiding any common resume mistakes is essential. You should showcase your skills, achievements, and career story accurately to get job-landing interviews and stand out within the competitive job market. Due to minor resume mistakes, a qualified candidate can miss his desired job opportunity.
Non AI Resumes’ expert team analyzed common resume mistakes by providing Free Resume Review Services and gained insights from recruiters and HR managers on common mistakes in a resume. In this article, we will discuss 10 common resume mistakes highlighted by recruiters and the analysis that causes resume rejection. To avoid any rejection, fix the following mistakes while writing the resume.
1. Spelling, Grammar, and Typographical Errors
Spelling, grammar, and typographical mistakes are minor errors that negatively impact the hiring manager and easily distract the recruiter from observing achievements and qualifications. According to Joel Winter, an award-winning recruiter and talent acquisition leader, “spelling and grammatical errors happen on about 5% of the resumes I see. Most are extremely minor, but if I had a nickel for every hiring manager that threw out a resume for a typo.”
In addition, you should print out your resume to proofread and utilize a free tool like Grammarly to scan your resume for contextual spelling mistakes, because nothing screams unprofessional and careless more than typos and grammatical errors in a resume. The reader can easily be distracted from your qualifications due to these mistakes. Ensure your resume is well-organized and error-free to showcase your qualifications effectively.
2. Cluttering Your Resume with Irrelevant or Outdated Details
Many job seekers make the critical mistake of including outdated, irrelevant, or overly personal information on their resumes. Details, such as marital status, age, hobbies, religious or political beliefs, salary history, or health information, not only fail to add value, but they can also introduce bias or raise privacy concerns. These inclusions suggest the applicant is not aligned with modern resume standards and may even cause their resume to be disregarded entirely. Stick to professional, relevant content and avoid anything not directly related to the job you are applying for.
Your resume should highlight recent, role-specific accomplishments that demonstrate your value. Avoid listing jobs from over 15 years ago unless they are directly relevant, and regularly update your contact details, skills, and achievements. Every line on your resume competes for attention, so remove anything that does not serve the goal of landing an interview. Generic templates, lack of customization, and failure to research the role or company are also common missteps. Tailor your resume for each application, and always proofread to ensure clarity, relevance, and professionalism.
3. Overdesigned or Poorly Formatted Resumes
When it comes to resume formatting, simplicity wins. A clean, easy-to-skim layout with consistent fonts, sizes, and clear headings helps recruiters quickly understand your background without distractions. Avoid elaborate designs, excessive colors, or graphics often make it harder for humans and Applicant Tracking Systems (ATS) to read your resume. White space, bullet points, and standard formatting help organize key information and make your content stand out for the right reasons. Fancy visuals or templates should be reserved for your personal website, not your resume.
Many job seekers make the mistake of using complex templates or downloading designs that are not ATS-friendly. These can hide important content and reduce your chances of being seen. Instead, stick to a simple, text-based format saved as a PDF or Word format to preserve layout and ensure compatibility. The goal is to communicate your value clearly, not to impress with design. Remember, hiring managers and recruiters care more about what your resume says than how it looks. Keep it straightforward so your message, not your formatting, gets noticed.
4. No Keywords, No Achievements, Just Buzzwords
To make it parse through applicant tracking systems (ATS) and grab a recruiter’s attention, it is essential to include relevant keywords from the job description in a natural and meaningful way. Avoid obvious keyword stuffing or overused buzzwords, which can come across as inauthentic or forced. Instead, focus on weaving keywords into your descriptions where they fit organically. You can Non AI Resumes to fine-tune your resume with your unique voice and ensure your language flows smoothly.
Equally important is balancing your resume’s structure. Avoid dense blocks of text or overwhelming lists of bullet points. Use concise paragraphs to describe your roles and supplement them with bullet points that highlight measurable achievements and qualifications. Do not just list responsibilities, showcase accomplishments using action verbs and quantifiable results to make your resume keyword-optimized and compelling.
5. Resume Length: Striking the Right Balance
One common resume mistake is having a document that’s either too long or too short. Ideally, a resume should be one to two pages, depending on your experience level and the job you are targeting. A resume that exceeds two pages can appear unfocused or overwhelming, while one that’s too brief may suggest a lack of experience or effort. Focus on including only the most relevant and impactful details, using bullet points and concise sentences to improve readability.
To maintain clarity and effectiveness, use strong action verbs and quantifiable results to showcase your contributions. Avoid repetition, filler words, and outdated or irrelevant information that does not support your qualifications. A well-structured, clearly written resume highlights your strengths and shows you respect the hiring manager’s time.
6. Incorrect or Missing Personal Information
One of the most common and easily avoidable resume mistakes is providing incorrect or incomplete contact information. This not only prevents recruiters from reaching out but can also raise concerns about your attention to detail. Your resume’s primary purpose is to land an interview, but missing or inaccurate contact details directly undermine that goal.
Equally important is how and where you place your contact information. Avoid inserting it into the header of a Word document or using an image, as applicant tracking systems (ATS) often cannot read those formats. When the ATS cannot detect your contact details, your resume may be flagged as incomplete, which reduces your chances of moving forward in the hiring process.
7. Unprofessional Email? Instant Red Flag
Your email address is often the first impression a recruiter sees, so it should reflect professionalism. An address tied to a nickname or alter ego, like “hipster.hottie,” can distract recruiters from your qualifications and make you appear less serious about the role.
Stick to a simple, professional format using your name, such as firstname.lastname@email.com. This ensures your application is taken seriously and keeps the focus on your experience, not your email handle.
8. No Metrics, No Impact: Show Results That Matter
Recruiters look for more than job responsibilities because they want clear evidence of the impact you have made. Quantifiable achievements, such as increased sales, improved retention rates, or measurable business growth, show that you are results-driven and capable of delivering value.
Without numbers to back up your work, your resume can appear vague or unimpressive, which showcases that you merely maintained duties rather than drove success. Highlight metrics wherever possible to demonstrate initiative and show the tangible results of your efforts.
9. Generic Resumes Fail: Customize for Every Job
One of the most common and costly mistakes job seekers make is using the same resume for every application. Recruiters can quickly spot a cookie-cutter resume, and it often signals a lack of effort or genuine interest in the role. As Stefan Lilienkamp, Managing Partner and Recruiter at ClarusApex shared that untailored applications can lead not only to being ignored but even blacklisted.
To stand out, tailor your resume for each job by aligning it with the job description. Highlight relevant skills, accomplishments, and use targeted keywords to match the role. This not only demonstrates interest and fit but also helps your resume pass through applicant tracking systems (ATS) and reach human eyes.
10. Using Repetitive Words or Phrases
Repeating the same words or phrases on your resume can make your experience seem generic and uninspired. It suggests a lack of attention to detail and can cause a recruiter to overlook your unique contributions in each role.
Instead, vary your language with strong, action-oriented verbs and tailor descriptions to reflect the distinct responsibilities and achievements of each position. This demonstrates thoughtfulness and helps your accomplishments stand out.
