How to Identify Weak Sections in Your Resume

A resume that hides its own flaws will never get you past the first screening. Identifying weak sections in your resume is the first step toward a compelling, recruiter‑friendly document. In this guide we’ll walk through proven checklists, step‑by‑step audits, and AI‑powered tools from Resumly that help you pinpoint and fix problem areas. By the end you’ll have a clear action plan to turn every weak spot into a strength.

Why Spotting Weak Sections Matters

Employers spend an average of 6 seconds scanning each resume (source: Jobscan). In that tiny window, any vague bullet, outdated format, or missing keyword can cause your application to be discarded. Detecting weak sections early saves time, reduces rejection rates, and improves your chances of passing both human and automated ATS reviews.

Common Weak Areas Checklist

Below is a quick reference you can print and use while reviewing your own resume. Mark each item as Pass, Needs Improvement, or Fix.

• Header & Contact Info – Is the email professional? Is a phone number included?
• Professional Summary – Does it convey a clear value proposition in 2‑3 sentences?
• Work Experience – Are achievements quantified? Are verbs action‑oriented?
• Skills Section – Does it match the job description keywords?
• Education – Is the format consistent and relevant?
• Formatting & Layout – Is the font readable, spacing consistent, and length appropriate?
• ATS Compatibility – Are there hidden tables, graphics, or unusual fonts?
• Buzzwords & Jargon – Are you overusing clichés like “team player” without evidence?
• Proofreading – Any spelling or grammar errors?
• Customization – Does the resume speak directly to the target role?

Mini‑conclusion: Use this checklist to quickly locate the weak sections in your resume before diving deeper.

Step‑By‑Step Guide to Auditing Your Resume

1. Export to Plain Text – Save a copy as .txt to see how an ATS reads it. Look for broken lines or missing information.
2. Run an ATS Scan – Upload to the free Resumly ATS Resume Checker. Note the “score” and highlighted problem areas.
3. Compare Against Job Descriptions – Copy the top 3 bullet points from a posting and paste into a word‑cloud tool. Highlight missing keywords in your resume.
4. Quantify Every Achievement – Replace vague statements (“responsible for sales”) with numbers (“increased sales by 22% in Q3”).
5. Check Readability – Use the Resume Readability Test to ensure a 7‑8 grade level.
6. Detect Overused Buzzwords – Run the Buzzword Detector and replace clichés with concrete results.
7. Get a Human Review – Share with a mentor or use the free Resume Roast for candid feedback.
8. Iterate – Apply the feedback, re‑run the ATS scan, and repeat until your score improves by at least 15 points.

Mini‑conclusion: Following this systematic audit will reveal the weak sections in your resume that most candidates overlook.

Do’s and Don’ts for Strengthening Each Section

Mini‑conclusion: Applying these do‑and‑don’t rules directly addresses the most common weak sections in your resume.

Real‑World Example: Before and After

Before:

Software Engineer
- Worked on a team.
- Fixed bugs.
- Used Java.

Why it’s weak: No impact, vague verbs, no numbers, and no alignment with a specific role.

After (Resumly‑enhanced):

Software Engineer – Mobile Apps
- Delivered 5 high‑impact features that increased user retention by 18% within 6 months.
- Reduced critical bugs by 30% through automated testing frameworks (JUnit, Selenium).
- Led a cross‑functional team of 4 developers, coordinating Agile sprints and code reviews.

The revised version quantifies achievements, uses powerful verbs, and matches keywords like “mobile apps” and “Agile”.

Mini‑conclusion: Transforming weak bullet points into results‑focused statements eliminates a major weak section in your resume.

Quick Self‑Assessment Quiz

Tick the boxes that apply to your current resume:

• My header includes a professional email and LinkedIn link.
• My summary tells a recruiter why I’m the perfect fit for the target role.
• Every work‑experience bullet starts with an action verb and includes a metric.
• My skills list mirrors at least 70% of the keywords from the job posting.
• The document passes an ATS scan with a score above 80.
• No tables, images, or unusual fonts are present.
• I have removed all generic buzzwords.
• I have proofread for spelling and grammar errors.

If you answered “No” to any of these, those are the weak sections in your resume you should prioritize.

Frequently Asked Questions

1. How often should I audit my resume?

You should perform a quick audit before every application and a deeper review once every 6 months or after a major career change.

2. Can AI tools replace a human reviewer?

AI tools excel at spotting formatting and keyword gaps, but a human can assess narrative flow and cultural fit. Use both for the best results.

3. What if my ATS score is low but recruiters still like my resume?

A low ATS score often means you’ll miss out on many opportunities. Consider creating two versions: an ATS‑optimized version and a design‑rich version for direct referrals.

4. How many keywords should I include?

Aim for 5‑7 core keywords that appear in the job title, required skills, and responsibilities. Over‑stuffing can trigger spam filters.

5. Is it okay to use a functional resume format?

Functional formats hide employment gaps but confuse most ATS systems. If you have gaps, address them briefly in a chronological format and use the summary to explain.

6. Should I list every certification I have?

Only include certifications that are relevant to the target role. Irrelevant items dilute the impact of your core qualifications.

7. How do I measure improvement after fixing weak sections?

Track interview callbacks before and after changes. A 20‑30% increase in callbacks is a strong indicator of success.

8. What’s the best way to stay updated on resume trends?
