Most engineers lose points not on the logic but on the delivery — racing through a system-design answer, mumbling the trade-off, or ending every sentence like a question. Corie scores how you actually sound and trains it, so you explain your thinking like the senior in the room.
In behavioral and system-design rounds alike, interviewers read confidence from how you talk through it — pace, pauses, and whether you sound sure of the trade-off you just made.
Nerves push your pace up while you reason out loud. Corie shows your words-per-minute against the band where interviewers follow you best.
Thinking in silence is fine — filling it with “um” isn't. Train the deliberate pause that reads as composure under a hard question.
State the decision, don't ask it. A statement that ends on a falling pitch sounds like a senior who's made the call before.
Decades of research: delivery moves trust, competence and persuasion — often before your words land.
These describe general patterns in how listeners perceive voices — not a promise about one interview. Corie trains the acoustic signals this research measures, on your device.
Read the line on screen or answer a real engineering question. Thirty seconds is enough; your pitch draws live as you speak — nothing is uploaded.
Depth, steadiness, pace, pauses, clarity and energy — measured against the targets for confident speech, with the one thing to fix first.
Short, guided reps with live feedback so you can hear and feel the change — not just read a tip.
Corie plays the interviewer for software engineers, asks role-tailored questions aloud, and scores your delivery and what you said — so the real thing feels like the second time.
Not a form to fill in — a real back-and-forth. The AI asks the questions engineers actually get, pushes on the follow-ups, then scores what you said and how you sounded.
A tough AI interviewer asks about conflict, ownership and a hard trade-off — and the follow-ups. Scored on substance and delivery.
Talk through your approach, your trade-offs and your debugging out loud — the way you do in the room — and hear where you lost them.
