There is a gap between knowing your answer and being able to say it. Most people close that gap live, in the interview, on the question that mattered most.
Practice is the exam to Prepare's study guide. It asks a question, you answer out loud, and the next question follows from what you actually said, the way a real interviewer works. Nothing is read off a list.
At the end you get a scorecard: what landed, what stayed abstract, where you sped up under pressure, and a note on every individual answer.
It reacts to your answer
Follow-ups come out of what you said, not from a fixed script.
A scorecard, not a vibe
Notes on every answer, plus pace and filler words.
Typed mode too
Practise by typing when you cannot speak freely. Same price.
One credit per session, whether you choose voice or text. Taken when the round starts and refunded in full if you leave before answering anything, so opening a round to look at it costs nothing. Reviewing a finished session afterwards is free.
