Met recruiters at an online job fair for US military veterans. Recruiter (initials: N. R.....lives in Pennsylvania) had no problem responding to emails before the application, but then ghosted me after applying - obviously he basically only cared about his application KPI and not actually getting people through to the end of his pipeline. This was a near entry-level position, and I fit the vacancy announcement almost perfectly (US military veteran w/ requisite university degree). As a former hiring manager myself that has had to work with recruiters before, I found it completely unprofessional. This type of work by recruiters in my previous company would not have been tolerated. Clearly this recruiter lacked the ability to accept responsibility for performance (and, if he can't get hiring managers on board, likely has issues working well in teams).
