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

1. do recruiters and HR professionals evaluate blockchain experience during the screening stage?

2. whether you look for open-source contributions, GitHub commits, DAO activity, or just interview performance?

3. 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.
