Common Mistakes That Kill Your Chances
Each mistake includes why it hurts, how to fix it, and before/after examples
Vague or Generic Job TitlesHIGH
Why it hurts
- Hiring managers can’t quickly see your level of responsibility
- ATS may not match your experience to senior detective keywords
- It dilutes the impact of specialized investigative work
How to fix
- Replace generic titles with precise ones (e.g., "Lead Homicide Detective" or "Cybercrime Investigator")
- Add a brief qualifier that reflects rank or specialty
- Align the title with the job posting’s terminology
❌ Before
Detective, City Police Department
✓ After
Lead Homicide Detective – City Police Department
ATS Tip
Include exact keywords from the posting such as "lead detective" or "forensic investigator"
Detection Rules
title contains only "Detective" without qualifier
title length < 10 characters
Resumly Tip
Add a specialty or rank to make your title instantly recognizable.
Listing Unrelated or Outdated SkillsMEDIUM
Why it hurts
- Clutters the skills section and lowers relevance score
- ATS may penalize for low keyword density
- Recruiters waste time scanning irrelevant items
How to fix
- Audit each skill for direct relevance to investigations (e.g., evidence handling, interview techniques)
- Remove generic office software unless explicitly required
- Prioritize law‑enforcement certifications and forensic tools
❌ Before
Skills: Microsoft Word, Photoshop, Data Entry, Interviewing, Surveillance
✓ After
Skills: Criminal Investigation, Evidence Collection, Interview & Interrogation, Digital Forensics (EnCase), Surveillance Operations
ATS Tip
Match at least 3–5 core investigative keywords from the job ad
Detection Rules
skills list contains consumer‑tech tools unrelated to law enforcement
more than 3 generic office software items
Resumly Tip
Trim the list to the top 8 skills that directly support detective work.
Omitting Quantifiable AchievementsHIGH
Why it hurts
- Fails to demonstrate impact and results
- ATS often looks for numbers to rank candidates
- Hiring managers prefer concrete evidence of success
How to fix
- Add metrics such as case clearance rates, number of arrests, budget saved, or training hours delivered
- Use the formula: Action + Context + Result (e.g., "Led a team that solved 12 cold cases, increasing clearance rate by 25%")
- Keep numbers concise and relevant
❌ Before
Investigated organized crime cases and prepared reports.
✓ After
Investigated 18 organized‑crime cases, leading to 14 convictions and a 30% reduction in regional gang activity; authored 22 comprehensive investigative reports used as precedent in court.
ATS Tip
Include numbers (%, $, #) within the first 100 characters of each bullet
Detection Rules
bullet points lack digits
no percentage or count present
Resumly Tip
Every bullet should contain a measurable outcome whenever possible.
Non‑Standard Section HeadingsLOW
Why it hurts
- ATS may not recognize custom headings and skip content
- Recruiters skim familiar sections and may miss key info
- Inconsistent headings look unprofessional
How to fix
- Use conventional headings: "Professional Experience," "Education," "Certifications," "Skills," "Awards"
- If you need a specialty section, add it as a sub‑heading under a standard heading
❌ Before
Career Highlights
✓ After
Professional Experience
ATS Tip
Stick to common headings; avoid creative titles like "My Detective Journey"
Detection Rules
section heading not in list of standard headings
Resumly Tip
Standard headings improve both readability and ATS parsing.
Inconsistent Date & Location FormattingMEDIUM
Why it hurts
- ATS may misinterpret employment dates, causing gaps
- Recruiters can’t quickly assess career timeline
- Inconsistent formats look sloppy
How to fix
- Use a uniform date format (e.g., "Jan 2020 – Present")
- Place city, state after each employer name on the same line
- Align dates to the right margin for visual clarity
❌ Before
City Police Dept – 2020 to present – New York
✓ After
City Police Department, New York, NY Jan 2020 – Present
ATS Tip
Use month abbreviation (Jan, Feb…) and four‑digit year; avoid words like "currently"
Detection Rules
date contains "to" instead of dash
month written in full
Resumly Tip
Consistent formatting ensures ATS reads your timeline correctly.
