Interview Prep.io is a voice-based AI interview coach that runs realistic mock interviews tailored to your role, seniority, and the exact job you're applying for — then hands you a hiring scorecard, a STAR-method breakdown of every answer, the "secret notes" an interviewer would have scribbled in their notepad, and a gold-standard model answer for every question.

It is built for people who are tired of generic prep sites, lukewarm advice, and friends who say "yeah that sounded good" when it didn't.

The five things that make it different

1. Voice-first, not type-first Interviews are spoken. So is the practice. You talk, we transcribe, and the scoring grades the way you actually communicate under pressure — pacing, structure, filler, the works. No more typing perfect-looking answers you would never actually deliver.

2. STAR scoring that is brutally specific Every answer is graded on Clarity, Structure, Impact, and Conciseness. The transcript is color-coded by STAR component (Situation, Task, Action, Result), so you can see exactly where you skipped the Result, buried the Action, or rambled through the Situation. Most candidates discover, in one session, that they have been silently dropping the most important part of every answer for years.

3. The Interviewer's Secret Notes This is the feature people screenshot. After every answer, you get the unfiltered, candid feedback an interviewer would have written in their notepad — the stuff they would never say to your face. "Vague impact, no numbers, lost interest by minute two." It stings. That is the point. You finally know what they are really thinking.

4. Custom Prep with your real JD and resume Paste any job description, upload your resume, and the AI generates 5 fresh questions that mirror what that specific company and role would actually ask. Candidates regularly tell us their interviewer asked one or two of the generated questions word for word.

5. Model answers, not vague advice "Be more specific" is useless feedback. So every question comes with a gold-standard model answer written by the AI in the voice of a top candidate at your seniority. You see the exact bar you are being measured against, then you close the gap.

Who it is for

• New grads and interns prepping for the 2026 to 2027 recruiting season — especially in consulting, business, finance, and product
• Career switchers who need to translate experience into a new vocabulary
• Mid-level and senior professionals doing high-stakes loops where one weak STAR answer ends the process
• People who freeze under pressure and want hours of low-stakes reps before it counts
• Anyone who has ever walked out of an interview and thought "what did I just say?" It is not a resume builder, it is not a job board, and it is not a coaching marketplace. It is one focused tool that does one thing extremely well: get you ready to be in the room.
