Hey Product Hunt! I'm Barney, a first-gen sophomore at GW who built Mocha because I couldn't find interview prep that actually worked. You can practice alone. Read guides. Watch videos. But none of it recreates real interview pressure. The unexpected follow-up. The moment your answer trails off. So I built something that does. Mocha grades your behavioral interviews at McKinsey, Goldman, Amazon, and Google standard. Adaptive follow-ups. Firm-grade scoring across structure, clarity, ownership, and impact. Real feedback, not generic encouragement. Before we officially launched, 1,600+ students across 19 universities found it organically. 74% come back within a week. No ads. Free forever. One question a day. 5 minutes. Would love to hear what you think and happy to answer anything about the product or the build!
