About the Customer
BitSol needed to hire for a highly niche HR role, someone with strong analytical depth, a real appetite for technology, and the ability to work closely with GenAI initiatives. This wasn’t a typical HR hire, and the funnel was big: 400+ applicants.
In the past, a role like this could take months, manual shortlisting, back-and-forth scheduling, multiple tools, and inconsistent evaluation across candidates.
With InterWiz, BitSol ran the entire funnel in a structured, automated way with less than 2 hours of human HR involvement until the final stage.
The Challenge
With over 400 applicants, manual shortlisting and scheduling quickly became unmanageable. We were spending more time coordinating interviews than actually evaluating candidates.
When the funnel is large and the role is specialized, traditional screening breaks down fast:
- 1High volume makes it hard to stay consistent
- 2Scheduling becomes a bottleneck
- 3Manual shortlisting takes weeks
- 4The team spends time coordinating instead of evaluating
- 5Great candidates can get lost in the noise
BitSol needed a way to evaluate analytical capability & technical appetite at scale without burning HR bandwidth.
The Approach
Instead of relying on manual screening and scheduling, BitSol used InterWiz to automate the funnel end-to-end:
- Automated resume shortlisting based on role-specific criteria
- Fully automated interview scheduling
- Structured screening to assess analytical thinking and tech appetite
- Automated second-round interviews for shortlisted candidates
- Clear rankings and reports at every stage (resume → screening → analytical)
What the Funnel Looked Like
Before: time-heavy, coordination-heavy
With InterWiz: structured and fast

And the best part: HR only stepped into live calls at the final stage.
What Was Automated
Here’s what BitSol reported from the process:
- CV shortlisting: automated
- Interview scheduling: ~15 minutes
- Screening + shortlisting for ~50 candidates: automated
- Second-round interviews for 13 candidates: automated
- Report review for shortlisted candidates: under 45 minutes
- Finalists interviewed by humans: under 1 hour total

Instant rankings were available at every stage (CV, screening, analytical), making decisions fast and defensible.
The Result
A high-quality hire from a 400+ applicant funnel in 3 weeks and < 2 hours of total HR involvement before the final decision stage.
Key outcomes:
- No calls required until the final stage
- Candidate handling fully automated up to the final interview
- Seamless workflow with BitSol’s ATS
- Faster decisions with consistent, structured evaluations
We wouldn’t have been able to evaluate 400 candidates in 3 weeks without InterWiz. Scheduling alone used to be a nightmare, now it’s just a few clicks.
Why This Mattered
This wasn’t just about saving time. BitSol needed a hiring process that could handle complexity:
- Evaluate for depth, not just surface-level screening
- Stay consistent across a large funnel
- Reduce coordination overhead
- Produce structured evidence at every stage
From hundreds of applicants to one confident hire. The funnel stayed fast, structured, and seamless.
