3. Choosing—and Maximising—Your Recruiter Partnership
Align by Stack
Solidity devs gravitate toward Plexus or EC1 Partners; Rust/Substrate engineers often use Storm2 or Signify.
Show Proof of Work
Open‑source repos, on‑chain deploys and audit links speak louder than résumés; recruiters pitch those URLs directly to founders.
Expect Coding‑Challenge Prep
Top desks supply sample smart‑contract exercises or CTF‑style exploits. If none are offered, ask.
Negotiate Tokens Wisely
Seek vesting schedules ≥ 2 years with cliff ≤ 6 months; recruiters will benchmark recent deals.

Solidity & Hardhat Testing – Security‑first smart‑contract patterns and fuzz testing.
Rust/Substrate Development – Building custom parachains or L2s on Polkadot / Cosmos.

DeFi Risk & Quant Modelling – Python/R skills to model liquidity pools and impermanent loss.
DevOps for Web3 – EVM node orchestration, chain‑indexing pipelines and Grafana/Prometheus monitoring.
