You can try taking the recruiters fees out of my salary offer but if your offer is 15% less than the three or four other offers I usually have - good luck with that.

I’ve worked with local recruiters almost exclusively over the past 20 years. If I send you a resume directly, I have no way of knowing whether you looked at, how much of your job req is fluff, what the necessary and nice to have skills are etc.

When I work through a recruiter, they’ve already been debriefed by other candidates who interviewed for the same position and they can tell me what the interviewer prioritizes.

I’ve also worked with recruiters from the other end as a hiring manager (actually Dev lead), I would call the recruiter back and give feedback.
