Duos is an AI-powered mock interview simulator designed to help job seekers identify and improve their blind spots by practicing real interview scenarios, thereby increasing their chances of getting a job offer. Its core philosophy is to let users practice repeatedly in a risk-free environment until they are no longer nervous in real interviews.
Purpose
Duos mainly addresses pain points for job seekers in interview preparation, such as a lack of realistic practice, not knowing where their own problems lie, and receiving no feedback after being rejected. By simulating the interview process of real companies, it lets users become familiar in advance with the pace of interviews and the types of questions, and clearly know what needs improvement.
Main capabilities
- Generate interviews based on job links: Users can paste public job links (such as LinkedIn job pages), and Duos will analyze and extract information such as the company, team, and job requirements to generate a personalized interview process.
- Multi-stage simulation: Covers three stages: recruiter initial screening, skills deep dive, and hiring manager interview. Users can run the entire process completely or focus on a single stage.
- Voice interaction: Conducted through voice conversation, simulating oral expression in real interviews, and users can pause at any time to organize their thoughts.
- Real-time feedback and reports: After the interview ends, a structured report is provided, pointing out "red flag" and "green flag" behavior patterns, and giving specific improvement suggestions and sample answers.
- Retry and assistance: Users can go back and re-answer questions, skip questions they are not ready for, or get sample answers based on their resume.
- Diverse interviewer styles: Provides AI interviewers with different personalities and styles, increasing the diversity and challenge of practice.
- Privacy protection: Audio is not stored, data is not sold or used to train AI, and users can delete data at any time; resumes are de-identified before AI reads them.
