Stop guessing why you're not getting hired. Duos is a live voice interview simulation. Paste a job link, like a LinkedIn job post, and it builds the company, the role, and the question set around it. Then you talk out loud with an interviewer you pick, from encouraging to flat-out hostile, and run the full hiring loop: recruiter screen, skills deep-dive, manager round. Or, for last-minute prep, a quick mock interview of just the stage you're worried about. The first interview is free. No app trial, and nothing to cancel. IT FEELS LIKE THE REAL THING Your interviewer talks, reacts, pushes back, and changes tactics based on what you say. You'll know when you're losing them, while there's still time to win them back. STUCK? YOU'RE IN CONTROL If you freeze mid-answer, ask for a hint. You can retry an answer, skip a question entirely, read what's on the interviewer's mind, or get a full example answer built on your background and CV. KNOW EXACTLY WHAT TO FIX Learn what the real interviewers never tell you. Your red flags and green flags, meaning the specific moments that formed their opinion. The patterns you repeat without noticing, with real quotes pulled from your own answers. Fix them, practice again, and watch the same mistakes stop showing up. WHY NOT JUST CHATGPT? A chatbot can't read the room. It drifts out of character, agrees when you are wrong, and leaves you a wall of notes. Duos stays in character, pushes back like a real interviewer, runs the whole process, and hands you a game plan. PRIVATE BY DESIGN No human ever hears you. Voice recordings are never stored, sessions are processed automatically, and CV uploads are encrypted. Stop guessing. Start getting offers. SUBSCRIPTION Your first personalized mock interview is free, including overall feedback and part of the debrief with the AI coach. A subscription unlocks unlimited interviews and analytics. Subscriptions auto-renew. You can change your plan or turn off auto-renewal in your Apple Account settings up to 24 hours before the renewal date. When canceled, access expires at the end of the current period. AUDIO & AI TRANSPARENCY Interview audio is transcribed by Deepgram (SOC 2 Type 2 certified, acting as our data processor) in flight and never stored. It is never linked to your email or account details. Transcripts, chat inputs, and preferences power your personalized interviews via Large Language Models (LLMs) hosted in an isolated, enterprise-grade Azure environment with no runtime connection to external providers. No personally identifiable information is sent to the models, and neither Duos nor the Microsoft environment trains AI models on your data.
