Most candidates never find out what actually went wrong.
Interviewers evaluate on specifics — a clear story, a real number, you owning a decision — not just whether you sounded confident. You can answer every question and still lose the offer without knowing why. PrepSignals shows you exactly which moments cost you, in plain language, before the real interview.
Paste your job description
We pull the role, company stage, and domain so questions match your actual interview.
Speak naturally
Voice-first mock interview. We transcribe with bias correction for Indian English and domain jargon.
Get the signal report
8 signals scored with verbatim quotes, conversation metrics, and a 4-bucket recommendation.
Built for candidates who take this seriously — including your first one.
Not generic AI chat. A structured interview simulator that grades on evidence, not vibes.
Backed by your own words
Every rating links back to a direct quote from your answer — never an opaque number you have to just trust.
8 things that actually matter
Technical depth, story structure, business impact, ownership, communication, adaptability, and more — the same things a real interviewer is quietly scoring.
Real benchmarks, explained
How much you talk vs. listen, how fast you respond, how many times you interrupt — each one explained in plain terms, backed by interview research.

“The questions were specific to my JD. The debrief pointed to the exact answer where I lost points and why. That's senior-interviewer-level feedback.”
