Chainlink interview questions with answers
Hey everyone! I’ve got a Chainlink engineer interview coming up and honestly, I’m equal parts nervous and excited. I’ve spent the last four years as a full-stack dev in Layer 2 blockchain—mostly building dApps, writing Solidity smart contracts, and handling off-chain data with React/Node.js. The role focuses a ton on Chainlink tools (Price Feeds, VRF, Automation) and scenarios like debugging janky contracts or syncing on-chain/off-chain data smoothly.
For folks who’ve tackled this interview before:
What prep strategy worked best for you? Did you grind docs, build projects, or focus on mock scenarios?
Any gotchas or must-know tips? Common pitfalls or topics that caught you off guard?
Resources worth prioritizing? Hidden courses/docs or mock interviews that actually helped?
How do you balance fundamentals vs. Chainlink deep dives? Should I obsess over the protocol’s nitty-gritty or double down on core smart contract/dev skills?
Thanks in advance—kinda nervous but really hoping to nail this.
