Common Mistakes That Kill Your Chances

Each mistake includes why it hurts, how to fix it, and before/after examples

Missing specific statistical software keywordsHIGH
Why it hurts
  • Recruiters and ATS look for exact tool names to match job requirements
  • Generic terms like "data analysis" don’t convey depth of expertise
  • Missing keywords cause your resume to rank low in keyword searches
How to fix
  • Audit the job posting for required software (e.g., R, SAS, Python)
  • Create a dedicated "Technical Skills" section listing each tool with proficiency level
  • Embed tool names within achievement bullets (e.g., "Used R to automate data cleaning, reducing processing time by 30%")
❌ Before

Proficient in data analysis and statistical modeling.

✓ After

Proficient in R (v4.2), Python (pandas, NumPy), SAS 9.4, SPSS, and SQL for data manipulation and predictive modeling.

ATS Tip
Include exact software names and versions as they appear in the posting to boost keyword match.
Detection Rules
Look for generic terms like "data analysis" without accompanying tool names
Cross‑check listed skills against a curated list of statistical software
Resumly Tip
Our parser flags missing software names and suggests top industry tools based on your experience.
Vague impact statementsHIGH
Why it hurts
  • Hiring managers can’t gauge the magnitude of your contributions
  • ATS algorithms favor numbers and measurable outcomes
  • Lack of specifics makes you blend with other candidates
How to fix
  • Replace "Improved model accuracy" with a quantified result (e.g., "Improved model accuracy from 78% to 92%")
  • Add context such as sample size, time frame, or business impact
  • Use action verbs and concrete metrics (%, p‑value, revenue, cost saved)
❌ Before

Developed predictive models for customer churn.

✓ After

Developed a logistic regression model that reduced customer churn by 15% (from 8% to 6.8%) over 12 months, saving $250K in revenue.

ATS Tip
Start bullet points with a verb and include at least one number or percentage.
Detection Rules
Bullet points lacking digits or percentage signs
Sentences beginning with generic verbs like "Responsible for"
Resumly Tip
Our AI suggests quantifiable alternatives for each responsibility bullet.
Inconsistent or non‑ATS‑friendly date formatsMEDIUM
Why it hurts
  • ATS may fail to parse employment dates, causing gaps in your timeline
  • Hiring managers may misinterpret tenure length
  • Inconsistent formatting looks unprofessional
How to fix
  • Standardize all dates to "MMM YYYY" (e.g., Jan 2020)
  • Use an en‑dash (–) between start and end dates
  • If still employed, write "Present" instead of "Current"
❌ Before

January 2020 – Present

✓ After

Jan 2020 – Present

ATS Tip
Use the exact "MMM YYYY" pattern with a single en‑dash; avoid commas or extra words.
Detection Rules
Date strings not matching the pattern /^[A-Za-z]{3} \d{4} – (Present|[A-Za-z]{3} \d{4})$/
Resumly Tip
We auto‑standardize dates and highlight any that don’t meet ATS standards.
Listing responsibilities instead of achievementsHIGH
Why it hurts
  • Employers want to see results, not just duties
  • ATS scores higher when bullets contain action verbs and outcomes
  • Responsibilities add length without value
How to fix
  • Convert each duty into a result‑focused bullet (e.g., "Managed data pipelines" → "Streamlined data pipelines, cutting processing time by 40%")
  • Focus on the business impact of your work
  • Limit each role to 4–6 achievement bullets
❌ Before

Responsible for cleaning and preparing datasets for analysis.

✓ After

Cleaned and transformed 10+ large datasets, reducing preprocessing time by 35% and enabling faster model deployment.

ATS Tip
Begin each bullet with a strong verb and include a measurable outcome.
Detection Rules
Bullets starting with "Responsible for" or "Managed" without follow‑up metrics
Resumly Tip
Our tool rewrites generic duties into achievement‑oriented statements with suggested metrics.
Including irrelevant academic courseworkLOW
Why it hurts
  • Clutters the resume and distracts from professional experience
  • ATS may penalize overly long sections
  • Hiring managers focus on applied skills, not theory courses
How to fix
  • Remove undergraduate courses unrelated to the target role (e.g., "Introduction to Philosophy")
  • If you must list coursework, keep it to 2–3 most relevant items under a concise "Relevant Coursework" heading
  • Prefer showcasing projects or publications over course titles
❌ Before

Relevant Coursework: Linear Algebra, Probability Theory, Introduction to Philosophy, Art History

✓ After

Relevant Coursework: Linear Algebra, Probability Theory, Advanced Statistical Modeling

ATS Tip
Limit coursework to 2–3 items that directly support the job description.
Detection Rules
Course lists exceeding three items
Presence of non‑technical subjects
Resumly Tip
We highlight and suggest removal of non‑essential coursework to keep your resume focused.
