Hiring Automation Case Study: 73% Faster Recruitment Pipeline
Company: ScaleWorks (project management SaaS, Series A, 120 employees, scaling to 200)
Challenge: Aggressive hiring plan (80 roles in 12 months) overwhelmed 2-person recruiting team
Solution: Automated resume screening, interview scheduling, feedback collection, and candidate communication
The Hiring Bottleneck
ScaleWorks needed to double headcount in 12 months to support growth. The recruiting team (1 Head of Talent, 1 Recruiting Coordinator) was already at capacity hiring 3-4 people monthly.
Manual process consumed:
| Activity | Hours/Week | Pain Points |
|---|
| Resume screening (400+ applications/week) | 22 hours | Inconsistent, slow, candidates waiting days for response |
| Interview scheduling coordination | 16 hours | Email tennis, calendar conflicts, double-bookings |
| Sending interview prep materials | 4 hours | Manual emails, frequent forgotten attachments |
| Collecting interviewer feedback | 8 hours | Chasing busy interviewers, delays in decisions |
| Candidate status updates | 6 hours | Keeping candidates informed, answering "where are we?" emails |
| Offer letter generation | 4 hours | Copy-paste errors, inconsistent language |
| Total | 60 hours | Only 2 FTE for 80 roles = impossible |
"We were hiring 3 roles monthly and barely keeping up. Leadership wanted us to 5× that to hit growth targets. With manual processes, we'd need to hire 8 recruiters just to manage the admin work. That made no sense." - Priya Sharma, Head of Talent, ScaleWorks (interviewed July 2024)
Additional problems:
- Candidate ghosting: 32% of candidates who passed initial screen never responded to schedule interviews (likely accepted other offers during delay)
- Interview panel burnout: Hiring managers complained about endless interview scheduling emails
- Inconsistent experience: Candidate communication quality varied based on recruiter workload
The Automated Solution
ScaleWorks automated five critical workflow steps:
Automation 1: AI Resume Screening
Workflow:
When application received in Greenhouse (ATS):
Step 1: AI extracts key information
- Years of relevant experience
- Skills matching job requirements
- Education background
- Location/timezone
- Current company/role
Step 2: Score against requirements
- Must-haves (binary yes/no): e.g., "5+ years Python experience"
- Nice-to-haves (scored 0-10): e.g., "Experience with microservices"
- Cultural fit signals (0-10): e.g., startup experience, remote work history
Step 3: Calculate overall score (0-100)
- Must-haves not met: Auto-reject with polite email
- Score 70-100: Auto-advance to recruiter review
- Score 50-69: Flag for manual review (edge cases)
Step 4: Send automated response
- High scores: "We're impressed! Next step is..."
- Marginal scores: "We're reviewing and will update you within 3 days"
- Rejections: Polite decline with encouragement to apply for other roles
Time saved: 18 hours weekly
Before vs After:
| Metric | Manual | Automated | Change |
|---|
| Applications reviewed/week | 400 | 400 | - |
| Time spent screening | 22 hours | 4 hours (reviewing flagged cases) | -82% |
| Time to first response | 3.2 days avg | 8 minutes avg | -99.8% |
| Screening consistency | 68% (varied by recruiter fatigue) | 94% | +38% |
Automation 2: Smart Interview Scheduling
Workflow:
When candidate passes screen:
Step 1: AI sends personalized calendar invite request
"Hi [Name], we'd love to schedule your first interview. Please select a time that works for you: [Calendly link with team availability]"
Step 2: Candidate selects time from available slots
- Calendly checks interviewer calendars in real-time
- Respects timezone differences automatically
- Prevents double-booking
Step 3: Automated confirmation workflow
- Calendar invite sent to candidate + interviewer(s)
- Interview prep materials attached (company overview, role description, what to expect)
- Reminder sent 24 hours before interview
- Zoom link auto-generated and included
Step 4: Post-interview automation
- Thank you email sent to candidate within 1 hour
- Feedback request sent to interviewers (Typeform survey)
- Next steps communicated based on interview stage
Time saved: 14 hours weekly
Before vs After:
| Metric | Manual | Automated | Change |
|---|
| Time to schedule interview | 2.8 days avg (back-and-forth) | 6 hours avg (candidate self-schedules) | -92% |
| Scheduling errors (wrong time/person) | 12% of interviews | <1% | -92% |
| No-show rate | 18% | 7% | -61% (better reminders) |
| Interviewer satisfaction | 6.2/10 | 8.4/10 | +35% |
Automation 3: Structured Feedback Collection
Workflow:
After each interview:
Step 1: Automated feedback request (sent within 30 mins of interview end)
- Typeform with structured questions
- 5-min to complete
- Mobile-friendly
Step 2: Reminder system

Step 3: Feedback aggregation
- AI summarizes key themes from all interviews
- Flags concerns or discrepancies
- Generates decision recommendation
Step 4: Decision dashboard
- Recruiter + hiring manager see aggregated feedback
- Clear "Advance/Hold/Reject" recommendation
- One-click decision + automated candidate communication
Time saved: 7 hours weekly
Before vs After:
| Metric | Manual | Automated | Change |
|---|
| Feedback completion rate | 64% (many interviewers forgot) | 92% | +44% |
| Time to collect all feedback | 4.2 days avg | 8 hours avg | -93% |
| Decision speed (all interviews → offer/reject) | 6.8 days avg | 1.4 days avg | -79% |
Automation 4: Candidate Communication Pipeline
Workflow:
Automated touchpoints throughout journey:

| "Black hole" complaints (no updates) | 38% of candidates | 4% | -89% |
Automation 5: Offer Letter Generation
Workflow:
When decision is "Extend offer":
Step 1: AI populates offer template
- Candidate name, role, level, team
- Compensation (pulled from approved offer in ATS)
- Start date, benefits, equity details
- Manager name, reporting structure
Step 2: Legal/compliance check
- Validates salary within approved band
- Ensures equity grant within pool limits
- Flags if non-standard terms detected
Step 3: Approval routing

- Sent via DocuSign for e-signature
- Candidate receives within 2 hours of decision
Time saved: 3.5 hours weekly
Before vs After:
| Metric | Manual | Automated | Change |

"The automation let us scale hiring 2.6× without adding recruiting headcount. More importantly, candidates loved the experience - fast responses, clear communication, no scheduling headaches. Our offer acceptance rate jumped from 68% to 84% largely because we moved faster than competitors." - Priya Sharma, Head of Talent
Lessons Learned
What worked well:
- AI screening accuracy improved over time - Started at 89%, now 96% as model learned from recruiter corrections
- Candidates loved self-scheduling - "Finally, no email tennis!" was common feedback
- Hiring managers appreciated structured feedback - Clear decision frameworks vs endless Slack discussions
- Speed became competitive advantage - Often had offers out before competitors finished first round
Challenges faced:
- Initial AI screening too strict - Rejected good candidates due to keyword mismatches. Tuned sensitivity down.
- Interviewer resistance to forms - Some preferred unstructured feedback. Compromise: form + optional narrative.
- Timezone scheduling complexity - Needed fine-tuning for global candidates. Now works well.
Advice for similar implementations:
- Start with scheduling automation - Biggest time sink, easiest to automate, immediate candidate experience improvement
- Don't fully automate rejections initially - Human review of borderline candidates prevents good people slipping through
- Invest in email copywriting - Automated doesn't mean robotic. Warm, personal tone matters.
- Track candidate feedback religiously - They'll tell you if automation feels impersonal
