Recruiters — how do you actually check if someone’s blockchain experience is real?

Over the last few months, I’ve seen a strange pattern while helping our talent acquisition team searching for mid-level blockchain developers. The pattern is almost everyone’s résumé reads the same — “Built dApps on Solidity, contributed to a DeFi protocol, worked with Chainlink oracles.”From a recruiter’s side, I can imagine it’s nearly impossible to tell who’s actually worked on real blockchain architecture and who’s just followed tutorials. I’m curious to understand how do recruiters and HR professionals evaluate blockchain experience during the screening stage?whether you look for open-source contributions, GitHub commits, DAO activity, or just interview performance?What are the signals that grab your attention towards if a developer really understands smart-contract logic, consensus, or gas optimization or these are just buzz words used in resumes using AI tools (this is a very common trend to use GPTs for resume writing)Asking this openly so that both recruiters and developers can understand the what actually happens we candidate submits resume and get call for interview from 100s of applicants.It’ll also help many of us prepare better for interviews and shape our project portfolios in the right direction.

You’re right — blockchain resumes have started sounding like they’re written by the same AI model. 😅

We can’t rely on just keywords anymore (“DeFi,” “Chainlink,” “gas optimization”). So we look for traces of real work.

Here’s what usually helps us separate real builders from tutorial followers 👇

GitHub with depth, not just activity. We check commit patterns, PR discussions, and whether the project evolved over time. A repo cloned and pushed in one day is a red flag.

Ability to explain design decisions. If you can tell why you used Chainlink or how you handled gas spikes, it stands out immediately.

Public footprint. Hackathon entries, Etherscan-verified contracts, DAO proposals — even small contributions show authenticity.

Version awareness. Real devs remember what framework or version they struggled with — GPT resumes rarely do.

Communication clarity. Explaining your project like you’d explain it to a non-tech founder is a skill most good Web3 engineers naturally build.

At the screening stage, we don’t expect perfect code but we do expect proof of ownership. Show what you’ve built, not just what you’ve read.

That’s honestly one of the most essential recruiter takes I’ve read here.

From a developer’s side, it’s easy to underestimate how visible “proof of work” really is We assume recruiters don’t have time to check GitHub or Etherscan, but clearly, the experienced ones do.

A few things I’ve noticed that seem to make a difference when applying:

Explain the “why,” not the tool. Instead of writing “used Chainlink oracles,” I now write why I needed it (e.g., off-chain price data for liquidation logic). That context helps recruiters sense real experience.

Document as you build. Even small build logs or Mirror posts show journey, not just result. Recruiters apparently notice that.

Focus on one real projects worked. Having one real dApp or contract with measurable on-chain activity is stronger than listing 5 boilerplate repos.

Show collaboration. Hackathons or DAO discussions reveal how you think, not just how you code.

What this thread highlights is that blockchain hiring isn’t about keyword matching — it’s about traceable contribution and clarity of thought. If both sides understood that early, half the frustration in screening would vanish.

wow I really appreaciate this thread. I never thought I will get this insight. Keeping eye on the thread
