A little bit more detail, I think that the top of funnel needs to be engineers doing extremely intelligent, programmatic searches - aided by low cost virtual assistants to do some tedious human level filtering where required by law. High likely match candidates are then sent to the recruiter along with the engineer's notes as to why the candidate is a good fit, from a technical perspective. The recruiter then leads a team of customer success personnel whose jobs are to transparently communicate with the candidate and guide them along the funnel in a high EQ way.
