Claim
Interviews are a two-way street. If you want great people, act like it. Give them full context, treat them like a strategic hire, no expired gimmicks like 'sell me this pen', and pay well.
Mechanism
Early-stage is hard, so compensate SDRs like adults with a % of closed-won deals they source. Optimize for quality over spam by being transparent about quota, attainment, process, and career goals.
