What EVM interview questions should I expect as a blockchain developer? I’m preparing for technical interviews, and the Ethereum Virtual Machine still feels tricky.
If you know common EVM questions or what interviewers usually ask, please share. I’d also appreciate tips or resources to help me understand EVM concepts and improve my skills.
Thanks for any advice!

Hey dont worry, I can understand you and I was there sometime. Its okay to find you nervous when coming to EVM as its a vast and deep topic to study. I would suggest you to start with basics and understand how EVM executes smart contracts, work with gas usage methods, Opcodes and storage etc You can expect questions around how gas works, stack vs memory vs storage, reentrancy, delegatecall, and the lifecycle of a transaction. I’d recommend resources like the Ethereum yellow paper (for advanced understanding), blogs like "EVM Illustrated", and videos from Patrick Collins or EatTheBlocks. Keep building small projects or debugging bytecode—it really helps. You’ve got this! Keep going—confidence grows with practice.

I faced several technical questions in my Ethereum interview. They asked me to explain the storage and memory layouts of the Ethereum Virtual Machine. I described the difference between persistent storage and temporary memory.
I also explained how contract bytecode works, including function selectors and function call structure. Gas costs were a big topic. They wanted details on SSTORE, SLOAD, warm SLOAD, and MLOAD opcodes. I discussed slot packing and how it saves gas by packing variables efficiently.
They asked about the differences between variable arrays, dynamic arrays, and mappings. I explained when to use each for storage and access efficiency. Upgradeable contracts and proxies came up next. I showed how proxies delegate calls and keep storage for upgrades. They wanted to know the difference between Externally Owned Accounts and smart contract accounts.
MEV was another topic, especially risks like frontrunning and sandwich attacks. Finally, they asked about common smart contract exploits, such as reentrancy and untrusted calls, and how to avoid them.
If you want a blockchain career, you need to know these Ethereum interview questions. They are now common for Solidity and smart contract roles.
