The biggest mistake when calculating recruitment costs is to focus solely on the tools. The real cost lies in man-hours. A team that handles resume screening, scheduling, initial screening, and first interviews is using the time of high-cost professionals on a step that, for most positions, is repetitive and highly standardizable. In recent benchmarks, recruiters have started conducting more interviews per hire than they did a few years ago, while the number of applications per opening has also grown significantly.
To understand the impact, consider three cost categories: reviewing resumes, initial screening, and coordinating initial interviews. Market studies show that recruiters can spend about 23 hours just reviewing resumes for a single hire, and that scheduling interviews can take anywhere from 30 minutes to 2 hours per candidate. In hiring processes with dozens or hundreds of applicants, this quickly becomes a drain on productivity.
Where the money goes
Imagine a job opening with 150 applicants: if a senior professional or recruiter needs to spend, on average, 10 to 15 minutes reading, sorting, and deciding what to do with each resume, that alone amounts to 25 to 37 hours of work. If they then have to schedule, conduct, and document initial interviews with a portion of those applicants, the cost rises even further.
Now multiply that by the hourly cost of the person in that role. A senior recruiter or business partner is not cheap for the company. And, in addition to their salary, there is the opportunity cost: while that person is stuck in the initial stage, they are unable to focus on employer branding, building relationships with managers, filling critical positions, and improving the pipeline. Recruitment benchmarks show that teams are dealing with more open positions, more applications, and longer processes, which puts even more pressure on this first stage
What Solu automates best
This is exactly where Solu delivers the greatest value. Instead of having the human team conduct the initial interview with each candidate, Solu interviews everyone, compares their responses, and provides a shortlist ready for a decision. This reduces the screening time and relieves HR of the burden of manually interviewing people who shouldn’t even be considered for the final round.
In practice, Solu replaces three time-consuming tasks: thoroughly reviewing resumes, conducting initial screenings, and manually comparing candidates. The benefit isn’t just speed—it’s consistency. Everyone answers the same questions in the same format, and the recruiter receives comparable data rather than scattered notes and subjective impressions.

The financial benefit, in plain language
If you replace 30 hours of manual screening with an automated interview from Solu, you’ll start saving your team time right away. If this also eliminates 15 or 20 initial meetings, the savings grow even more. And if the shortlist is stronger, you reduce the risk of interviewing fewer candidates than you should and having to reopen the position later because the pipeline didn’t yield enough quality candidates.
Benchmarks support this reasoning. The average cost per hire in the U.S. remains around $4,683 for non-executive roles and is significantly higher for leadership positions. At the same time, companies are taking longer to hire and conducting more interviews per opening, which confirms that the operational cost of recruitment is rising, not falling.
When ROI comes faster
Automating the initial conversation with AI tends to generate a more tangible ROI for high-volume positions, roles with highly repetitive criteria, and processes where recruiters currently spend too much time “clearing the backlog.” It also works very well when a company wants to improve the quality of its shortlist without expanding its HR team.
In other words: the more your operation relies on manual screening and initial interviews on a large scale, the greater the return on Solu tends to be. And the more senior the person involved in this stage, the more expensive it becomes to maintain the old model.
The point isn’t to replace recruiters with machines. It’s to use machines for tasks that are repetitive and costly, so that humans can focus on what truly requires judgment. The initial interview, the initial screening, and comparing multiple candidates are exactly the kind of work that falls into this category.
