Vetting Process

How We Assess Blockchain Developer Candidates

During our vetting process, we evaluate candidates with questions designed to reveal depth of expertise, problem-solving ability, and communication skills.

Explain the concept of 'Gas' in Ethereum. How do you optimize a contract to minimize gas costs?

What is a Reentrancy attack, and how do you prevent it in Solidity?

Describe the difference between Proof of Work (PoW) and Proof of Stake (PoS).

How do you upgrade a deployed smart contract? What patterns do you use (e.g., Proxy pattern)?

Explain how a Merkle Tree works and its usage in blockchain.

How do you ensure true randomness in a smart contract using an Oracle?

What are the security risks associated with bridging assets between chains?

Walk us through the structure of a typical dApp architecture.
