    Any tips for spotting bugs and optimizing smart contracts during Solidity interviews?

    I freeze up the moment I’m asked to review code. I’ve been prepping for blockchain dev interviews, and Solidity is quite difficult for me.

    I know the basics like reentrancy risks, gas optimization tricks, storage vs memory differences but all of that makes sense in theory.

    But when an interviewer puts a smart contract in front of me and says, “Find the bugs,” or “Make this more efficient,” my brain just stops working. Sometimes I blank out on obvious stuff like forgetting the difference between call and transfer, and other times I overthink and make things worse.

    Has anyone else been through this? Are there any exercises, tools, or even silly tricks you used to get better at this kind of review work?

    Would really appreciate any advice, resources—or even funny fails—just to know I’m not alone.

    Thanks in advance! 🙏
