Earlier quoted context omitted.
Not the OP, but commission-based recruiting seems to incentivise the wrong kind of recruiting, i.e. "find someone we can shove down their throat". I would personally rather pay an experienced recruiter by the hour, even if it meant fewer (hopefully higher quality) leads.
I agree, but the incentive for hourly is to wait as long as possible to introduce the candidate, right?
Evidently OP did a good job, and made them feel like they were getting high value.
