I received an interview call for a Smart Contract Developer role at an MNC. I have experience creating smart contracts, building decentralized applications, and working with standards like ERC-20 and ERC-721.
How can I clearly explain my work and achievements during the interview? Should I bring a portfolio of projects or focus more on describing technical challenges I solved?
Thanks for your help!

To showcase smart contract development skills, start by describing your projects clearly. Explain how you created and deployed smart contracts, such as for tokens, NFT marketplaces, or DeFi protocols. List the tools you used, like Solidity, Hardhat, or Truffle. Highlight steps you took to ensure security, such as writing unit tests or using analysis tools like Slither.
Discuss challenges you solved, such as reducing gas costs by optimizing contract logic or handling edge cases. Provide examples, like customizing ERC-20 or ERC-721 tokens to meet specific needs.
Prepare a portfolio with live projects or GitHub links. Include verified contracts on Etherscan and test case documentation. A short demo or video walkthrough of a project can add value.
Share how you collaborated with teams, like aligning contract functionality with business requirements. Mention working with designers or managers to achieve project goals.
Be ready to discuss technical details, such as optimizing gas usage, avoiding reentrancy attacks, and managing vulnerabilities like overflows. Focus on clear, direct answers that show your expertise and practical experience.
