Why Resume Mistakes Matter

Recruiters spend an average of 6–7 seconds on their first scan of your CV. A single typo, generic wording, or missing keyword can land your resume in the rejection pile before a human ever reads it. The good news? Many of these mistakes can be fixed quickly—and AI tools make the process faster than ever.

1. Weak or Generic Professional Summary

The Mistake: Vague summaries like "Hard-working professional seeking new opportunities" say nothing about your value. Recruiters skip past them.

How AI Fixes It: AI analyzes your experience and the job description to craft a targeted summary with relevant keywords, quantifiable achievements, and a clear value proposition. Use our AI CV tailoring tool to generate a professional summary tailored to each job.

2. Missing or Misused Keywords

The Mistake: Your CV might be perfect for humans, but if it lacks the right keywords from the job description, ATS systems will reject it before recruiters ever see it.

How AI Fixes It: AI extracts key terms from the job posting and mirrors them in your CV while keeping your content natural. It identifies missing skills and suggests where to add them. Our resume checker flags missing keywords and our tailoring tool automatically optimizes your CV for each application.

3. Vague Job Descriptions (No Numbers)

The Mistake: Bullet points like "Responsible for managing projects" or "Improved processes" don't show impact. Recruiters want to see results.

How AI Fixes It: AI helps reframe responsibilities into achievement-focused statements. It suggests quantifiable metrics (percentages, numbers, timeframes) and action verbs. It preserves your facts while making them more impactful.

4. Spelling and Grammar Errors

The Mistake: Typos and grammar mistakes signal carelessness. Many recruiters reject resumes with errors immediately.

How AI Fixes It: AI-powered tools detect spelling and grammar issues across your entire CV. A good resume checker will flag these before you submit. Some tools also suggest clearer phrasing and more professional language.

5. One-Size-Fits-All Resume

The Mistake: Sending the same CV to every job shows lack of effort. Recruiters can spot a generic resume instantly.

How AI Fixes It: AI tailors your CV to each job in seconds. It reorders content by relevance, emphasizes matching experience, and adjusts your summary. Instead of spending hours customizing manually, you get a job-specific CV in under a minute with our AI CV tailor.

6. ATS-Unfriendly Formatting

The Mistake: Tables, columns, graphics, and fancy fonts can confuse Applicant Tracking Systems. Your content might be great, but if the format breaks parsing, your CV gets filtered out.

How AI Fixes It: AI resume tools use ATS-friendly templates and formatting. A resume checker can analyze your current format and flag issues. Our CV tailor produces clean, ATS-optimized outputs that preserve your content while ensuring compatibility.

7. Irrelevant or Outdated Information

The Mistake: Including outdated skills, irrelevant experience, or personal details that don't belong can dilute your message and hurt your chances.

How AI Fixes It: AI helps prioritize content by relevance to the job. It can suggest what to emphasize, what to trim, and how to reframe older experience. It focuses on what matters for each role.

8. Poor Section Order

The Mistake: Leading with weak sections or burying your best experience can cause recruiters to miss your strengths.

How AI Fixes It: AI reorders sections and bullet points by relevance to the job. It surfaces your most matching experience and skills first, creating a narrative that aligns with what recruiters are looking for.
