Common Mistakes That Kill Your Chances
Each mistake includes why it hurts, how to fix it, and before/after examples
Using Generic Job TitlesHIGH
Why it hurts
- Recruiters skim for specific roles; "QA Professional" is too broad
- ATS keyword matching favors exact titles like "Software Tester" or "QA Engineer"
How to fix
- Replace vague titles with the exact role you performed
- Add seniority level if applicable (e.g., "Senior Software Tester")
❌ Before
John Doe QA Professional ABC Corp – 2019‑2023
✓ After
John Doe Senior Software Tester ABC Corp – 2019‑2023
ATS Tip
Match the title in the job posting; include both "Software Tester" and "QA Engineer" if relevant
Detection Rules
title contains "QA" without "Tester" or "Engineer"
Resumly Tip
Swap generic titles for the precise role you held to improve keyword hits.
Listing Duties Instead of AchievementsMEDIUM
Why it hurts
- Duty statements read like a job description, not a personal impact
- ATS rewards quantifiable results and action verbs
How to fix
- Start each bullet with a strong verb
- Add numbers, percentages, or time saved
❌ Before
- Executed manual test cases for web applications
✓ After
- Executed 250+ manual test cases, identifying 35 critical defects that reduced production bugs by 22%
ATS Tip
Include measurable outcomes; use keywords like "identified", "reduced", "improved"
Detection Rules
bullets start with "Performed", "Executed", "Responsible for"
Resumly Tip
Turn tasks into achievements by quantifying impact.
Omitting Test Automation Tools & FrameworksHIGH
Why it hurts
- Automation expertise is a top requirement for modern testing roles
- ATS filters often look for tool names like Selenium, Cypress, JUnit
How to fix
- Create a dedicated "Technical Skills" section listing tools, languages, and frameworks
- Mention tools in experience bullets where you applied them
❌ Before
Technical Skills: Testing, Documentation
✓ After
Technical Skills: Selenium WebDriver, Cypress, JUnit, TestNG, Java, Python, Git, Jenkins
ATS Tip
Mirror the exact tool names from the job ad; avoid abbreviations unless widely recognized
Detection Rules
technical skills list missing known automation tools
Resumly Tip
Add a comprehensive tools list to capture keyword matches.
Skipping Metrics Like Defect Detection RateMEDIUM
Why it hurts
- Metrics demonstrate effectiveness and help differentiate you from other candidates
- ATS may rank resumes with numbers higher due to perceived specificity
How to fix
- Include key performance indicators (KPIs) such as defect detection rate, test coverage, or release cycle time
❌ Before
- Conducted regression testing for each release
✓ After
- Conducted regression testing for 12 releases, achieving a 95% defect detection rate and 30% faster release cycles
ATS Tip
Use percentages, ratios, and timeframes; keywords: "defect detection", "test coverage", "release cycle"
Detection Rules
bullets lack numeric values
Resumly Tip
Add quantifiable metrics to showcase testing impact.
Inconsistent Formatting & Long ParagraphsLOW
Why it hurts
- Recruiters spend seconds on each resume; cluttered layouts cause drop‑off
- ATS may misread sections if headings are non‑standard or spacing is irregular
How to fix
- Use clean bullet points, uniform font size, and standard headings
- Keep paragraphs under 2 sentences; prefer concise bullet lists
❌ Before
Professional Summary: I have worked as a software tester for several years and have experience in manual testing, automation, and reporting. I am detail‑oriented and enjoy working in agile teams.
✓ After
Professional Summary: Detail‑oriented Software Tester with 4+ years of experience in manual and automated testing. Proven track record of improving release quality by 22% in Agile environments.
ATS Tip
Standard headings (e.g., "Professional Summary", "Technical Skills") help ATS parse sections correctly
Detection Rules
paragraphs longer than 30 words
headings not capitalized
Resumly Tip
Adopt a consistent, ATS‑friendly layout with short, punchy bullets.
