Common Mistakes That Kill Your Chances
Each mistake includes why it hurts, how to fix it, and before/after examples
Using vague or non‑standard job titlesMEDIUM
Why it hurts
- Hiring managers may not recognize your role
- ATS keyword matching fails without exact titles
- Reduces perceived relevance to security positions
How to fix
- Replace generic titles with industry‑standard ones (e.g., Security Analyst, Information Security Analyst)
- Add a subtitle that includes key focus areas (e.g., Threat Monitoring)
- Align the title with the job posting you’re targeting
❌ Before
IT Specialist
✓ After
Security Analyst – Threat Monitoring
ATS Tip
Include the exact phrase "Security Analyst" and related keywords like "threat detection" in your title.
Detection Rules
Title does not contain "Security Analyst" or related keywords
Resumly Tip
Match your title to the role you’re applying for for maximum impact.
Listing generic responsibilities without impactHIGH
Why it hurts
- Fails to demonstrate value or results
- ATS looks for quantifiable metrics and action verbs
- Recruiters skim bullets and drop vague statements
How to fix
- Start each bullet with a strong action verb (Implemented, Reduced, Led)
- Quantify results (e.g., reduced incident response time by 30%)
- Mention specific tools and frameworks (SIEM, NIST, MITRE ATT&CK)
❌ Before
Responsible for security tasks and monitoring.
✓ After
Implemented SIEM monitoring across 200 endpoints, reducing incident response time by 30% and detecting 15% more threats.
ATS Tip
Embed high‑impact keywords such as "SIEM", "incident response", and "threat detection" within each bullet.
Detection Rules
Bullet points lack measurable metrics
No action verbs present
Resumly Tip
Show results, not duties, to prove your effectiveness.
Omitting relevant certificationsHIGH
Why it hurts
- Misses high‑value keywords that ATS prioritize
- Hiring managers may question your expertise level
- Certifications often act as a quick filter
How to fix
- Create a dedicated Certifications section
- List industry‑recognized credentials (CISSP, CEH, CompTIA Security+)
- Include the year obtained if recent
❌ Before
(none)
✓ After
Certifications: CISSP (2023), CompTIA Security+ (2021), Certified Ethical Hacker (CEH) (2022)
ATS Tip
Place certifications in a separate, clearly labeled section to ensure ATS extraction.
Detection Rules
No certification section present
Missing keywords like "CISSP"
Resumly Tip
Certifications are high‑impact keywords—make them visible.
Using inconsistent or non‑standard date formatsLOW
Why it hurts
- ATS may misinterpret employment dates
- Hiring managers can’t quickly assess tenure
- Inconsistent dates look unprofessional
How to fix
- Adopt a uniform MM/YYYY format for all dates
- Use the same separator (e.g., –) between start and end dates
- Avoid month names or textual ranges
❌ Before
Jan 2020 – Present
✓ After
01/2020 – Present
ATS Tip
Consistent MM/YYYY dates improve parsing accuracy across all ATS platforms.
Detection Rules
Dates not in MM/YYYY format
Resumly Tip
Standardize dates for ATS readability.
Including graphics, tables, or complex layoutsMEDIUM
Why it hurts
- Many ATS strip out visual elements, losing content
- Important information may be omitted during parsing
- Recruiters using plain‑text views see a broken layout
How to fix
- Replace tables with simple bullet lists
- Remove images and icons
- Use standard headings and plain text sections
❌ Before
<table><tr><td>Skill</td><td>Level</td></tr><tr><td>SIEM</td><td>Expert</td></tr></table>
✓ After
• SIEM – Expert • Incident Response – Advanced • Vulnerability Management – Proficient
ATS Tip
Keep the resume layout simple; ATS can only read plain text.
Detection Rules
Presence of HTML tables or image placeholders
Resumly Tip
Stick to simple formatting to ensure all content is captured.
