How a San Francisco SaaS Company Used Technical Interviews as a Service to Hire 11 Engineers in 8 Weeks
[Series B SaaS, San Francisco] · Technology
Results at a Glance
- Senior-engineer screening hours: 15/wk → 0
- Time to offer: 49 days → 16 days
- Final-round pass rate: 28% → 71%
The Challenge
Every technical screen cost a senior engineer an hour, plus prep and writeup. With 4 open backend roles and 300+ applicants, the team faced a choice: burn sprint capacity on interviews or filter hard on resumes and miss great engineers from non-brand companies.
The Solution
The Cognitive ran technical interviews as a service: every applicant got a live AI technical interview - system design and live problem-solving with adaptive follow-ups - within 48 hours of applying. Engineers reviewed evidence-scored shortlists with quotes and timestamps instead of running screens.
The Results
11 engineers hired in 8 weeks. Final-round pass rate more than doubled because humans only met candidates who had already demonstrated ability. Engineering reclaimed 15 hours a week of senior time. For teams asking how to hire software engineers without burning senior capacity, this split - AI runs depth at scale, humans decide - was the unlock.
We stopped outsourcing our roadmap to our interview calendar. The AI does the screens; our engineers do the final rounds and the shipping.
