Interview prep

Practice the work behind the question.

Choose a lane and role to see its real interview questions, what each tests, and a framework for strong answers. These are practice prompts and general guidance - not memorized scripts, and not every company interviews the same way.

Frontend Web3 Developer

Expect questions about frontend engineering, async state management, and wallet integration, plus a scenario where the role must respond to RPC failures, wallet incompatibility, contract migration, chain reorgs, phishing concerns, or a broken transaction flow. Interviewers are looking for evidence that the candidate knows where frontend implementation and wallet and chain state stop and smart contract architecture and product strategy begin.
