Common Mistakes That Kill Your Chances
Each mistake includes why it hurts, how to fix it, and before/after examples
Overusing Jargon Without ContextHIGH
Why it hurts
- Hiring managers may not understand niche acronyms
- ATS can misinterpret unknown terms and lower relevance score
- Reduces readability for nonâtechnical recruiters
How to fix
- Introduce each term with a brief explanation
- Pair jargon with measurable outcomes
- Replace obscure acronyms with their full form on first use
â Before
Developed DApp using ERCâ20, ERCâ721, and zkâSNARKs for highâthroughput transactions.
â After
Developed a decentralized application (DApp) on Ethereum using ERCâ20 tokens for payments, ERCâ721 NFTs for digital assets, and zeroâknowledge SNARKs to ensure transaction privacy, resulting in a 30% increase in user adoption.
ATS Tip
Include the full term first (e.g., "ZeroâKnowledge Succinct NonâInteractive Argument of Knowledge (zkâSNARK)") then use the abbreviation later.
Detection Rules
Contains acronyms without preceding definition
Lengthy string of technical terms without verbs
Resumly Tip
Define each blockchain term before using its abbreviation to keep both humans and ATS happy.
Missing Quantifiable AchievementsHIGH
Why it hurts
- Recruiters canât gauge impact
- ATS algorithms favor numbers and percentages
- Your resume looks like a list of duties rather than results
How to fix
- Add specific metrics (e.g., % increase, $ saved)
- Use action verbs followed by outcomes
- Compare before/after states
â Before
Worked on smart contract development for a DeFi platform.
â After
Engineered smart contracts for a DeFi platform that processed $12M in transactions monthly, reducing gas costs by 18% and increasing user retention by 22%.
ATS Tip
Place numbers early in bullet points to catch the ATS parser.
Detection Rules
Bullets lack digits or % signs
Sentences start with "Worked on" or "Responsible for"
Resumly Tip
Turn duties into achievements by adding concrete results and percentages.
Not Highlighting Relevant Blockchain PlatformsMEDIUM
Why it hurts
- Hiring managers look for platform expertise (Ethereum, Solana, Hyperledger)
- ATS keyword matching misses critical tech stacks
- You appear as a generic developer rather than a specialist
How to fix
- Create a dedicated "Blockchain Platforms" subâsection under Technical Skills
- List each platform with proficiency level
- Mention platform usage in project descriptions
â Before
Technical Skills: JavaScript, Python, Go, Rust.
â After
Technical Skills: JavaScript, Python, Go, Rust; Blockchain Platforms: Ethereum (Advanced), Solana (Intermediate), Hyperledger Fabric (Advanced).
ATS Tip
Include exact platform names as they appear in job postings.
Detection Rules
Technical Skills list lacks blockchain platform names
No mention of Ethereum, Solana, Hyperledger
Resumly Tip
Add a clear blockchain platform line to ensure keyword hits.
Using Generic Job TitlesMEDIUM
Why it hurts
- Reduces keyword relevance for niche roles
- Makes it harder for ATS to map experience to the target title
- Dilutes your brand as a blockchain specialist
How to fix
- Replace generic titles with specific ones (e.g., "Smart Contract Engineer")
- Align titles with those in the job description
- Add a brief qualifier if the role was internal
â Before
Software Engineer at XYZ Corp (2020â2023)
â After
Smart Contract Engineer â Decentralized Finance (DeFi) at XYZ Corp (2020â2023)
ATS Tip
Match at least one exact title keyword from the posting.
Detection Rules
Title contains "Software Engineer" without qualifier
No mention of blockchainâspecific role
Resumly Tip
Swap generic titles for blockchainâfocused equivalents to improve relevance.
Poor Formatting That Breaks ATS ParsingHIGH
Why it hurts
- Headers and tables can be ignored by parsers
- Unusual fonts or symbols cause data loss
- Recruiters may discard unreadable resumes
How to fix
- Use standard headings (Professional Summary, Technical Skills, Experience)
- Avoid tables, text boxes, and graphics
- Stick to common fonts like Arial or Calibri, 10â12pt
â Before
<table><tr><td>Project</td><td>Details</td></tr></table>
â After
Project: CrossâChain Bridge Details: Designed a Solidity bridge connecting Ethereum and Binance Smart Chain, handling 5,000 daily transactions.
ATS Tip
Save the final file as a plain PDF without embedded objects.
Detection Rules
Contains HTML tags or table markup
Uses special characters like âą or â
Resumly Tip
Keep the layout simple and linear; ATS love plain text structures.
