Every recruiter knows the pain: 4 hours to screen 20 candidates. 12 hours to schedule interviews. Weeks to close a single role. But here's what most hiring teams don't realize—your screening process isn't just slow, it's actively burning cash.
When Cognilium AI deployed[ Vectorhire](https://cognilium.ai/products/vectorhire) for a mid-sized tech company, the numbers told a story that changed how they thought about recruitment ROI forever.
The Real Cost of Manual Screening (And Why It's Worse Than You Think)
Let's do the math on a typical hiring sprint:
- 20 candidates per role × 12 minutes per screen = 4 hours
- 3 roles per month = 12 hours on initial screens alone
- Senior recruiter hourly rate: $45–65/hour
- Monthly screening cost: $540–780 (just for the first filter)
Now multiply that across your team. A 5-person recruiting department burns 60+ hours monthly on screens that could be automated—without sacrificing quality.
That's $3,000–4,000/month disappearing into repetitive work.
The Vectorhire Experiment: 105 Hours Saved, Zero Quality Loss
Cognilium AI ran a controlled deployment with a client facing aggressive growth targets. The brief: maintain candidate experience, improve shortlist accuracy, and cut time-to-hire.
Before Vectorhire:
- Time per candidate screen: 12–15 minutes
- Monthly screening hours: 120 hours (team of 3)
- Cost per screen: $9–12
- Time to shortlist: 14 days average
After Vectorhire (90 days in):
- AI-assisted screen time: 2–3 minutes (human review only)
- Monthly screening hours: 15 hours
- Cost per screen: $1.20–1.80
- Time to shortlist: 4 days average
Net impact: 105 hours saved per month. That's 2.6 full-time weeks returned to strategic hiring work.
What 105 Hours Actually Buys You
This isn't just about "doing less." It's about doing more of what matters.
With the reclaimed bandwidth, the client's team:
- Doubled stakeholder interview time (better hiring decisions)
- Launched an employer brand campaign (inbound applications +40%)
- Built a talent pipeline for Q2 roles (3-week head start)
The ROI wasn't just cost savings—it was strategic capacity that didn't exist before.
The Metrics That Changed the Conversation
Cognilium AI tracks four KPIs that traditional ATS platforms ignore:
1. Cost Per Screen
Manual: $9–12 | Vectorhire: $1.20–1.80
Savings: 85%
2. Time to Shortlist
Manual: 14 days | Vectorhire: 4 days
Improvement: 71%
3. Screening Throughput
Manual: 5 candidates/hour | Vectorhire: 20+ candidates/hour
Increase: 300%
4. False Positive Rate
Manual: 22% | Vectorhire: 8%
Quality gain: 64%
(Source: 90-day deployment, n=340 candidates, tracked via time-tracking and ATS integration)
Why This Isn't Just Another "AI Success Story"
Most recruitment AI vendors sell you on vague promises: "faster hiring," "better matches," "AI-powered." But when you ask for the raw data, the conversation gets awkward.
Cognilium AI builds differently:
- Open-source methodology: The ROI model is transparent. You can audit the math.
- No black-box scoring: Vectorhire explains why a candidate was shortlisted (or wasn't).
- Real-world stress tests: These numbers come from actual payroll data and time logs, not cherry-picked case studies.
You're not buying a promise. You're buying a system that shows its work.
The One Thing Every CFO Asks (And How to Answer It)
"How do I know this ROI will hold at scale?"
Fair question. Here's the sensitivity analysis Cognilium AI runs for every client:
| Scenario | Monthly Volume | Hours Saved | Cost Savings (Annual) |
|---|---|---|---|
| Small team (2 recruiters) | 30 roles/month | 40 hours | $28,800 |
| Mid-size (5 recruiters) | 75 roles/month | 105 hours | $75,600 |
| Enterprise (15 recruiters) | 200 roles/month | 280 hours | $201,600 |
Even in the worst-case scenario—50% volume, 50% efficiency—the payback period is under 4 months.

What Changes When You Actually Have Time
The hidden ROI isn't in the spreadsheet. It's in what your team stops doing wrong because they're no longer drowning.
- Fewer "gut feel" hires (because you have time to structure interviews)
- Better candidate experience (because you're not ghosting people for 2 weeks)
- Actual diversity progress (because bias-prone speed screening disappears)
One client put it bluntly: "We stopped hiring like we were firefighting."
The ROI Roadmap (What to Measure in Your First 60 Days)
If you're evaluating Vectorhire—or any AI hiring tool—here's the KPI stack Cognilium AI recommends:
Week 1–2: Baseline
- Track current time-per-screen (use a timer, not estimates)
- Calculate cost-per-screen (loaded recruiter rate ÷ screens/hour)
- Measure false positive rate (shortlisted candidates who fail first interview)
Week 3–6: Deployment
- Run AI screens in parallel with manual (trust, but verify)
- Log time saved per candidate
- Compare shortlist quality (interview-to-offer rate)
Week 7–8: Analysis
- Calculate net time saved (hours reclaimed – AI review time)
- Measure cost savings (delta in cost-per-screen × volume)
- Survey recruiter sentiment (are they using the extra time well?)
The goal: Provable ROI in 60 days, or the deployment needs adjustment.
Why Vendor Claims Don't Match Reality (And How to Spot It)
Most AI recruitment tools report "95% time savings" or "10x faster screening." If you ask for the dataset, you'll get a PDF with three cherry-picked testimonials.
Red flags to watch for:
- No before/after time logs (just surveys)
- ROI calculated on "opportunity cost" (not actual spend)
- Case studies that don't name the client or show sample size
What Cognilium AI does differently:
- Raw KPI visuals with source notes (you can validate the math)
- Anonymized dataset access (see the distribution, not just the average)
- Sensitivity analysis (so you know how much margin for error exists)
Transparency isn't a feature. It's the foundation.

The Bottom Line
105 hours saved isn't a vanity metric. It's 2.6 weeks of strategic capacity your team didn't have last quarter.
It's the difference between:
- Reacting to requisitions vs. building talent pipelines
- Spray-and-pray sourcing vs. targeted outreach
- Firefighting vs. future-proofing
The ROI is real. The data is transparent. The system shows its work.
The question isn't whether AI hiring saves time. The question is: what will you build with the time you get back?
