Your resume is your ticket to an interview. But even the smallest mistake can cause it to be filtered out by an Applicant Tracking System (ATS) or tossed aside by a busy hiring manager. In 2025, when AI and human recruiters are both sifting through hundreds of applications, you can't afford a single error.
Here are the most common resume mistakes and how to fix them immediately.
Mistake #1: Not Optimizing for Applicant Tracking Systems (ATS)
- The Problem: Your resume looks beautiful, but the ATS sees a garbled mess.
- The Fix: Use a clean, simple format with standard section headings (e.g., "Work Experience," "Education"). Stick to common fonts like Arial or Calibri. Avoid complex graphics, tables, or text boxes, as they often don't parse correctly.
Mistake #2: Focusing on Duties Instead of Achievements
- The Problem: Your resume is a list of your job responsibilities.
- The Fix: Employers don’t care what you were "responsible for." They care about what you achieved. Use action verbs and quantify your results. Instead of "Managed social media accounts," write "Increased social media engagement by 30% by launching a new content strategy."
Mistake #3: Too Long or Too Thin
- The Problem: Your resume is either a two-page autobiography or a sparse document with very little information.
- The Fix: The sweet spot is one page for most candidates with less than 10 years of experience. For senior professionals, two pages are acceptable. Prioritize what's most relevant to the job you're applying for, and don't be afraid to trim outdated or irrelevant experience.
Mistake #4: Overused and Generic Soft Skills
- The Problem: You list "team player" and "good communication" on your resume without any context.
- The Fix: Soft skills are best proven through your achievements and work experience. Instead of listing "problem-solving," show it in your work history with a bullet point like, "Identified and resolved a bug in the software that was costing the company an estimated $5,000 per month."
Mistake #5: Typos and Formatting Errors
- The Problem: A simple typo sends a clear message: you lack attention to detail.
- The Fix: Proofread your resume multiple times. Read it backward to catch errors you might have missed. Ask a friend or family member to review it as well. A polished document shows you are a professional who takes their work seriously.
