Start freeFor engineering managers preparing for leadership and bar-raiser rounds
A voice interviewer that pushes back the way a bar-raiser does. Then it marks up what you actually said, and you take it again. Watch one answer go from 9/16 to 14/16.
Your recordings, scores and stories are never shared with employers, recruiters or hiring platforms.
So we migrated the payments queue off the legacy cluster, and we got latency way down [from] → [to], which unblocked the Q3 launch.

HOW IT WORKS
Generic mocks are free now. What they do not give you is a second take on the answer that cost you the round.
TAKE 1
A full mock is 15 minutes, voice only. Every answer draws follow-ups until the weak spot shows.
MARKS
Every mark sits on a line you said. Practice feedback, never a hiring verdict.
...and we got latency way down, which unblocked the launch.
TAKE 2
Same question, same follow-ups. Both takes side by side.
I chose a two-week dual-write over a cutover. p99 went from 1.8s to 240ms.
PRICING
A full mock is 15 minutes of interview with follow-ups.
No subscription. Retakes are always free.
