Prep Sarthi's answer:
Google Gemini Live for the spoken interview, over a WebSocket, with the microphone captured and resampled in the browser through an AudioWorklet. The site is static and the back end is a Cloudflare Worker with a D1 database. Your CV is read in your own browser and goes only to Google, on your own key.
YieldStack's answer
YieldStack combines AI-assisted lender matching with hands-on commercial mortgage brokerage. Borrowers submit once, compare financing options, and work with a team that handles structuring, negotiation, and closing coordination. Borrowers approve lender outreach, with no upfront fees and a broker fee paid only at closing.
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.
YieldStack's answer
YieldStack helps borrowers evaluate the whole financing offer: rate, leverage, fees, reserves, prepayment terms, and closing requirements. Its platform organizes the process, while its brokerage team helps borrowers find suitable lenders and move the deal forward. One submission gives borrowers a coordinated financing process without an upfront brokerage fee.
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.
YieldStack's answer
Commercial real estate investors, developers, operators, and mortgage brokers seeking bridge, DSCR, fix-and-flip, construction, multifamily, and permanent financing across the United States.
Prep Sarthi's answer:
Indian graduates and early-career candidates preparing for the large service companies, where the panel interviews your resume and the round is short. It also suits anyone who has written a strong CV but has never said it out loud.
YieldStack's answer
Rommin Adl and Daniel Chesney founded YieldStack to simplify commercial real estate financing. The platform brings deal preparation, lender matching, offer comparison, and closing coordination into one workflow, combining AI-assisted analysis with human brokerage expertise.
Prep Sarthi's answer:
It came out of Interview Sarthi, a Windows app that helps during a live online interview. People kept asking for something to use before the interview rather than during it, and that is a different product, so it was built as one. It is made by one person in Delhi.
