What it is
Candidate ghosting is when someone actively engaged in a hiring process, replying to messages, booking interviews, discussing terms, suddenly stops responding without any formal withdrawal. No declined call, no "not interested" email, no explanation. The process was live one week and unreachable the next, with nothing in writing to say why.
It can happen at any stage: after an initial approach, after a screening call, after an interview that was booked and never attended, even after an offer has been extended or accepted. A candidate who accepts an offer and simply never shows up on day one is the costliest version of the same behaviour. What defines ghosting is not the stage it happens at, it is the absence of a closing message. A candidate who says no is a decline. A candidate who goes silent is an open question.
A candidate who stops replying hasn't said no. They just haven't said anything yet.
Why it matters
Every candidate in an active pipeline represents hours already spent: sourcing, screening, interview prep, sometimes a client presentation. When that candidate goes quiet, none of that work converts, and the client relationship absorbs the damage, particularly if the candidate had already been shortlisted or interviewed internally. The closer to offer stage it happens, the more expensive it gets, and the harder it is to explain to a client who was expecting a start date.
It is also getting more common, not less. Candidates increasingly run several processes with several agencies at once and simply follow whichever one moves first, dropping the rest without a word. Recent recruiter surveys put the share who have had a candidate go silent well above half, with a large share reporting it happens on a regular basis rather than as a rare exception. A pipeline that looks full on paper can already be half quiet, and a desk that does not track response patterns only finds out when a forecasted placement fails to close.
How boilr handles it
boilr does not try to guess why a candidate went quiet, that judgement stays with the consultant. What it does is make sure silence gets noticed instead of drifting. When a candidate in an active pipeline misses a scheduled call or does not respond after an agreed number of touches, your AI sales employee flags the task as stalled rather than leaving it sitting untouched, indistinguishable from everything else moving normally.
Before marking a candidate cold, it drafts a final check-in task, a short message giving them one clear opening to respond, so nothing gets quietly dropped without a deliberate decision. If they do go cold, the record does not disappear. Their profile, the stage they reached and where the process stalled stay in the Company Brain, so if a job-change or career signal brings them back into view later, whoever picks it up sees the full history instead of starting from zero.
