You can solve the problem. Then someone watches you code, asks you to talk through it, and you blank. That freeze is what interviews test. Not whether you can find the answer alone, but whether you can reason out loud under pressure. Interviewium is where you practice that part. WHAT IT IS A voice-first way to prep coding interviews. You speak your reasoning. Each thing you say becomes a card in a flow. You start with the brute force idea and talk your way toward the optimal one, one step at a time. WHO IT IS FOR Working engineers who want to switch jobs and aim high, but have no hours to grind problems all day. If you write code fine and freeze the moment you have to explain it, this is built for you. WHAT IT FIXES - No time to prep. Do a rep on your commute or between meetings. No laptop, no desk. - Freeze when watched. Rehearse the talking, not the typing, until it feels normal. - Tired of memorizing patterns. Reason through problems out loud and see why a solution works. HOW IT WORKS - Pick a problem and start talking. - Each voice input turns into a card you can see and build on. - Move from brute force to optimal as your flow grows. - Get feedback on your reasoning, not a pass or fail grade. PRICING An annual plan, or go month to month. No weekly plan. Cancel anytime. We charge because every practice session runs on a paid AI model, so there is no permanent free tier and no hidden fees.
