During my career, I was involved in recruiting efforts for experienced hires, typically professionals with 5 to 10 years of experience. One of my responsibilities included reviewing resumes and recommending a shortlist of candidates for interviews. While many resumes were professionally written and well-structured, a few stood out for all the wrong reasons—typos, missing punctuation, and vague content. One even read like a rough first draft.

When it comes to resumes, you don’t just want to make a good impression—you want to make a lasting one. Your resume is often your only shot at grabbing a hiring manager’s attention. Get your resume right, and you’ll significantly increase your chances of landing an interview.

So, where do things typically go wrong? Read on to discover the most common resume mistakes and how to avoid them.

You don’t want to just make a good impression; you want to make a lasting impression. Your resume is your first (hopefully not your last) chance to do that. Get your resume right, and you stand a good chance at getting an interview.

Misspellings and Grammatical Errors

Nothing gets your resume tossed aside faster than careless errors. In today’s digital world, there’s no excuse for submitting a resume with typos or grammar mistakes. Built-in spellcheck and grammar tools are standard in most word processors, yet many candidates still overlook them.

Take the time to read your resume multiple times before sending it. Better yet, ask someone you trust to proofread it. A second pair of eyes can catch missed mistakes and ensure your writing sounds polished and professional.

Resume Writers

Hiring a professional resume writer can be a wise investment—if approached correctly. Professional resume writers often help transform a good resume into a great one, increasing your chances of landing interviews.

However, the process should be collaborative. Simply sending over your career history and expecting a flawless result is a mistake. You must be actively involved so that the final product accurately reflects your experience, voice, and career goals.

  • Talk with your writer to provide context and direction.
  • Make sure your achievements and personality come through.
  • Be confident you can speak to every item listed in your resume.

Think of a resume writer as a partner—not a shortcut. The more effort you put into the process, the better the result.

Not Focused

A resume that lacks focus fails to communicate your value. Vague statements like “worked in marketing” don’t tell hiring managers what you accomplished. Your resume should highlight specific outcomes that show your impact in previous roles.

Instead of listing job duties, emphasize results. A more effective statement would be: “Developed cost-effective marketing campaigns that increased lead conversions by 30%.” Employers want to see measurable achievements that align with their hiring position.

Take the time to tailor each section of your resume to reflect the skills and experience most relevant to the job. A focused resume stands out and tells a clear story of your career trajectory and success.

Gaps in Your Resume

Employment gaps are more common than ever and don’t have to hurt your chances if addressed thoughtfully. Gaps should be acknowledged and explained with clarity and confidence, whether due to layoffs, company closures, or personal reasons.

One practical approach is using a functional or hybrid resume format, highlighting your skills and accomplishments rather than presenting a strict chronological timeline. You should also include any freelance, contract, or volunteer work completed during that period to demonstrate continued growth and activity.

Transparency is key. Avoid trying to hide employment gaps; instead, show how you remained productive and focused during those times. Employers value honesty and initiative, and they understand that careers rarely follow a perfect path.

No Keywords

Most companies and job search platforms use applicant tracking systems (ATS) to scan resumes before a human sees them. If hiring managers don’t see the right terms, your resume could be filtered out automatically—even if you’re fully qualified.

To improve your chances of passing these filters, include keywords from the job description that match your skills, industry, and experience level. The right keywords will also make your resume more compelling to human reviewers.

  • Use role-specific terms: Incorporate job titles, tools, and certifications relevant to the position.
  • Highlight soft and hard skills: Balance technical skills with traits like leadership and communication.
  • Reference job descriptions: Pull common phrases directly from listings for your target positions.

If you need help identifying powerful keywords, consider using resources like this guide to ensure your resume stands out digitally and in person.

A Politically Incorrect Email Address

It may seem obvious, but unprofessional email addresses still appear too often on resumes. Using something like “[email protected]” might reflect your personality, but it won’t win points with a hiring manager. It could get your application tossed before your experience is even considered.

Set up a dedicated, professional email account specifically for your job search. Ideally, use a variation of your full name. If your name has already been taken, consider adding a middle initial or a simple number to keep it clean and appropriate.

Remember, small details matter. Your email address is one of the first things a recruiter sees, so make sure it sets the right tone.

What You Do in Your Spare Time

Hiring managers often appreciate seeing a well-rounded candidate with interests outside of work. Including hobbies on your resume can add personality and show you’re more than just your job title. However, this section must be handled carefully to avoid unintentional bias or red flags.

Stick to neutral, broadly appealing interests and avoid any activity that could lead to discrimination—especially those related to politics, religion, or controversial organizations.

  • Safe choices: Sports, outdoor activities, travel, reading, volunteering
  • Risky mentions: Political affiliations, divisive causes, or anything that could spark bias

Before submitting your resume, review your resume for any content that could hurt rather than help. Keep it professional, relevant, and positive.

Include keywords in your resume that are used in job descriptions for jobs you want to apply for.
