10 Common Resume Mistakes That Cost You Interviews

Small resume mistakes can get you filtered out before anyone talks to you. Here are the ones recruiters see most often—and how to fix them.

1. Typos and grammar errors

Spelling and grammar mistakes suggest carelessness. Proofread every line, use spell-check, and have someone else read it. Read it out loud to catch awkward phrasing.

2. Missing or wrong contact info

Wrong email, old phone number, or no phone at all can cost you an interview. Double-check everything. Use a professional email address.

3. Generic summary or objective

"Hard-working professional seeking a challenging role" could apply to anyone. Replace with a specific summary of your experience and fit for this type of role, or skip it if it doesn't add value.

4. Vague bullets with no impact

"Responsible for marketing" says nothing. Add what you did, how, and what changed: "Led demand-gen campaigns that increased MQLs by 30% in 12 months." Use action verbs and numbers where possible.

5. No tailoring

Sending the same resume to every job signals you didn't care. Match keywords from the job description, reorder bullets so the most relevant experience is first, and adjust your summary for the role.

6. Bad formatting or length

Tiny fonts, no white space, or six pages of dense text make your resume hard to read. Use a simple font, clear headings, and 1–2 pages for most roles. Avoid tables and graphics if you're applying through ATS.

7. Unexplained gaps or odd dates

Long employment gaps with no note raise questions. Add a brief line (e.g. "Career break," "Contract work") or a short role. Use consistent date format and don't fudge months or years.

8. Irrelevant or outdated content

Listing every job since high school or hobbies that don't support your story wastes space. Focus on the last 10–15 years and roles that relate to the job. Cut the rest or summarize in one line.

9. Lying or exaggerating

Inflated titles, fake dates, or skills you don't have will surface in background checks or interviews. Be honest. You can frame experience positively without lying.

10. Wrong file or format

Sending a .doc when they asked for PDF, or a file named "resume_final_v3.pdf," looks unprofessional. Follow the posting's instructions and use a clear file name like "FirstName_LastName_Resume.pdf."

The Bottom Line

Fix typos, double-check contact info, tailor content, add impact to bullets, and use clear formatting. Avoiding these ten mistakes won't guarantee an interview—but it will keep your resume in the pile instead of the reject stack.
