Prep Sarthi VS Diffee

Prep Sarthi's answer

It interviews you from your own CV rather than from a question bank. It reads the resume you upload and asks about the projects on it, so the questions are the ones only you can be asked, and it asks again when an answer is thin. The report is measured rather than guessed: the pause before you started speaking, your words per minute and your filler words all come from your microphone.

Prep Sarthi's answer

Most tools cap how much you can practise, because a spoken interview costs them money every minute. Prep Sarthi runs on your own free Google Gemini key, so a pass buys unlimited practice instead of a set number of sessions. It also interviews in Hindi and Hinglish, which matters in India, where interviewers often switch language mid-question. And you can try it for twenty minutes without an account or a card.

Google Gemini Live for the spoken interview, over a WebSocket, with the microphone captured and resampled in the browser through an AudioWorklet.
