The Cost of a Bad Shortlist

Most recruiting teams can tell you their cost-per-hire. Very few could tell you what it cost the last time a hiring manager interviewed five people and didn't want any of them. I suspect the second number is often the bigger one, and the reason nobody knows it is worth looking at.

Cost-per-hire adds up sourcing costs, recruiter time, advertising and agency fees, then divides by the number of hires. That's a reasonable thing to measure. The trouble is what it counts as free, and the biggest thing it counts as free is the hiring manager's time.

Every shortlist a recruiter sends costs the manager something. They have to read the CVs, prepare for the first-round interviews, sit through them, and write up feedback. For five candidates, two to four hours is a conservative guess. For a senior individual contributor or a leader, a rough estimate puts that at somewhere between $150 and $600 of their time per shortlist, and that's before anyone has had a useful conversation.

If the shortlist is good, say three strong candidates with one standout among them, that time is well spent. If it's five people who cleared the keyword bar on paper and fall apart five minutes into a conversation, it's wasted. And the wasted afternoon isn't even the worst of it.

What does more damage is what bad shortlists do over time. A manager who keeps getting weak candidates starts to engage less. They skim instead of reading. Their feedback comes later. Eventually some of them start finding candidates on their own and going around the recruiting team altogether. None of that appears in cost-per-hire.

Following one bad shortlist

It helps to follow a single bad shortlist and see where the costs go. The manager sits through four interviews that lead nowhere. Then the recruiter goes back to the pool and sends a new batch a couple of weeks later, which means another round of the manager's time, and the role stays open while all this happens.

The open role has a cost of its own. One common rule of thumb puts the cost of leaving a role unfilled at 1.5 to 2 times its annual salary per year. By that estimate, a $90,000 role that stays open six extra weeks because it took three rounds of shortlists to find someone viable costs around $15,000 in lost productivity. Then add the manager's time, the recruiter's rework, and whatever decisions got put off because the person wasn't there to make them.

Eventually the hire gets made, and its cost-per-hire looks fine. Everything I just described was real, but it was spread across a dozen calendars that nobody adds up. I think this is why so many companies underinvest in screening. You don't fix a cost you can't see.

Why the shortlists are bad

So why do bad shortlists keep happening? Mostly because of how screening is done. The usual process is a resume review, maybe followed by a phone screen if there's time. A resume tells you what someone has done. It doesn't tell you how they think, how they communicate under a little pressure, or whether their stated experience holds up once they have to describe it out loud.

That pushes recruiters to optimize for the wrong thing. They learn to pick candidates who will look right to the hiring manager at the CV stage, and that's a different group from the people who will do well in an interview. The cleanest resume in the stack is often not the strongest person. And a recruiter working through 200 applications for one role, with no time set aside for phone screens, has to fall back on proxies, which pass along some weak candidates and miss some strong ones. The expensive part is less the occasional bad hire than all the interview time spent on people who should have been screened out at the start.

The shortlist is what screening produces, and its quality decides nearly every cost that comes after it. Yet most teams treat screening quality as a given rather than something they can design.

That's the part we set out to change with Asendia, and it's the reason we built it as a voice AI. A resume or a written questionnaire lets someone present their experience in its best light. A spoken conversation makes them describe it out loud, with follow-up questions they didn't see coming, which is much harder to script. Asendia has a structured conversation like that with every candidate, evenings and weekends included, and probes them against the specific criteria for the role. If a candidate says they managed a team, it asks about the scope, the outcomes, and the decisions they made. If they're vague about a requirement, the vagueness shows up in what the recruiter sees instead of traveling quietly along with the candidate to the hiring manager. What reaches the ATS is a list of people who have already had a real qualification conversation, with a structured summary and their own words attached.

The aim is fewer, better candidates per shortlist. Suppose a manager gets five people worth meeting instead of ten of mixed quality. Each cycle saves a couple of hours of their time, and across a quarter with many open roles that adds up to days. More important, the manager starts trusting the shortlists again. (For more on which pipeline numbers are worth watching, there's a separate post on recruitment KPIs that were built for a pre-AI world and what to track instead.)

Cost-per-hire is still a useful number. It just can't tell you what a screening process costs when it works badly. The fix usually has nothing to do with adding interview rounds or sign-offs. It happens at the screening step, so that what the hiring manager gets on a Tuesday morning is a short list that deserves their time.
