Introducing Rehersa: AI mock interviews that actually feel like the real thing

Most people prepare for interviews by doing things that look like work but don't feel anything like the real thing. They skim question lists, bookmark threads, maybe grind a few problems in silence the night before. Then they sit down in front of a real interviewer, on a real call, and realize the hard part isn't knowing the concept. It's saying something coherent out loud while someone watches you.

We built Rehersa for that gap — the uncomfortable space between "I know this" and "I can actually perform this under pressure." Today we're making it available so anyone can practice real interviews, with a real voice AI interviewer, on their own schedule.

What Rehersa is

Rehersa is a voice‑first AI mock interview platform. You talk to it the way you would talk to a real hiring manager. It asks follow‑ups, interrupts you when you ramble, and pushes when your answer stays too shallow.

You start by uploading your CV and pasting a job description. Rehersa uses both to shape the interview: which projects it digs into, which gaps it probes, and which follow‑ups it cares about. You choose the format — behavioral, technical, system design, or a general screen — and you get a structured interview, start to finish.

What it can do today

Right now, Rehersa focuses on doing a few things extremely well:

Voice‑based interviews: you speak your answers out loud. No typing walls of text into a chat box. This is the closest you can get to the real thing without another human on the call.

CV + job‑description personalisation: questions are grounded in what you've actually done and what the role actually needs. If your CV says you owned a migration, expect to be pushed on tradeoffs, incidents, and impact — not generic "tell me about a time you worked on a team" filler.

Multiple interview formats: behavioral, technical, system design, and a general "are you someone we want to work with" screen. Each format uses a different rubric and different kinds of follow‑ups.

Scored feedback on every answer: after the session, you get per‑answer scores on communication, confidence, structure, and depth — plus specific lines you could have said differently.

Why we think everyone should practice this way

The testing effect — the idea that being tested on material helps you retain it far more than re‑reading it — is one of the most robust findings in education research. Interviews are just a very high‑stakes, very human version of that.

Reading advice doesn't train the skill you're actually graded on: thinking on your feet, explaining tradeoffs under time pressure, handling follow‑ups that come from left field. Practicing those skills out loud, with something that pushes back, does.

Who Rehersa is for

If you're early in your career and trying to break into your first software role, Rehersa gives you a way to get reps without burning through your limited real interviews as practice. If you're mid‑career and aiming at more competitive companies, it gives you a place to shake off rust and sharpen your stories before you talk to a human panel.

It's also for people who don't want a subscription, a bootcamp, or a multi‑month program. You can run a single mock interview, get your feedback, and come back when you're ready for the next one.

Where we're going next

The current version of Rehersa is deliberately focused: great interviews, great feedback, no extra noise. From here, we're working on richer analytics over multiple sessions, deeper role‑specific playbooks, and ways to bring real‑world data from your past interviews into how you practice.

If you use Rehersa this week, you're still early. Your feedback will directly shape what we build next — what feels off, what feels scarily real, and what would make this your default way to prep.
