We had a notification service doing about 2M events per day. I redesigned the pipeline from synchronous to event driven…
PROBIX
What trade-offs did you navigate?
Interview design
We designed the interview to reveal, not to coach.
We didn't just add fraud detection. We designed every step of the interview to produce honest signal.
Orientation without coaching
Candidates hear what the interview covers. Not how to answer it. Context without strategy.
An unscored practice turn
The first attempt does not count. Candidates who need a moment can take it. The evaluation starts when they are ready.
Silence is not a problem
We do not interrupt pauses. Structured think time produces better answers and better signal.
Nothing missed before it ends
In recruiter led sessions, uncovered topics surface before the conversation closes. Coverage gaps do not become brief gaps.
Answer structure is measured, not assumed
Every behavioral response is analyzed for STAR completeness: did the candidate provide a Situation, Task, Action, and Result? The rate appears in the brief alongside competency scores so you know how much evidence you are actually working with.
We designed the interview to reveal who someone actually is - not to help them perform better than they are.
First of its kind
Every candidate has a voice. We measure what's in it.
The first communication style profile built for hiring decisions - derived from transcript and paralinguistic analysis and mapped to your role requirements.
“Concise and direct communicator who takes individual ownership. Structured responses with a professional tone.”

She paused for 12 seconds before answering.
Short answers in the first two minutes. Long pauses. A voice that sounded uncertain.
Most recruiters would have moved on.
