About

Duos is a gamified AI mock-interview app that turns interview preparation into an engaging, realistic simulation platform: you select from over 20,000 role-specific questions and face one of 64 AI-driven interviewer personas in scenarios tailored to roles across engineering, product, marketing, design, HR, and more. It offers playback of your responses, detailed feedback immediately after each session in a 20-minute debrief with an AI coach, progress-tracking metrics like “Interview Readiness,” and adapts dynamically; it analyzes your performance, adjusts scenarios, and builds a bespoke practice journey around your goals. Duos aims to make the practice experience faster than solo prep, cheaper than traditional coaching, and calmer than real interviews by letting you train in a safe environment, building consistency through daily 20-minute sessions, and reducing anxiety by leveling up your skill set rather than facing a high-stakes live interview.
