The only reliable cure for interview nerves is reps
Most interview advice aimed at nerves is some version of “just be confident,” which is about as useful as telling someone to just fall asleep. Confidence isn't a switch. It's a by-product of familiarity.
The reason a real interview feels terrifying is that almost nothing about it is familiar. You rarely speak about yourself under evaluation, out loud, to a stranger, in real time. Each of those is a skill, and none of them get exercised by reading interview questions silently in bed the night before.
This is why practice interviews move the needle where pep talks don't. When you've already answered “what's your biggest weakness” out loud a dozen times, the thirteenth — the one that counts — is just another rep. Your body has stopped treating it as a threat.
You don't need a friend to sit across from you or a coach you have to book weeks ahead. A live AI interview gives you the pressure of speaking in real time and the feedback to improve, on demand, as many times as it takes for the room to feel ordinary.
