I can't echo this enough! The one time I had an exceedingly positive experience with a recruiter, the role and company involved had been grossly misrepresented and had a very fractured org (which explained the rushed hiring / recruiting bit).

Good recruiters (i.e. retired software devs will likely not have bad intent or be clueless) will usually mean good, but can still screw you. Otherwise, most recruiters are econ majors or business majors who couldn't fill out excel sheets well enough to find a decent job, so they decided to try "recruiting". "in-house" recruiters, seemingly a new SF trend, generally aren't any more qualified (still have basically zero tech background) and seem to just be trying the hardest to "be cool" and set the stage for an over-blown behavioral interview.
