InterviewOS is an AI interview practice platform built to make mock interviews feel like the real thing. You pick your role, then sit a live session with an AI interviewer that asks follow-ups, challenges weak answers, and scores you after each response. Rounds range from intro to technical to leadership. It currently targets Software Engineering, Data Science, ML, and GenAI roles and runs on Windows. Pricing is credit-based, and you can start with 1 free credit.

• Live AI Interviewers: Practice in real-time sessions with an AI that interrupts, challenges, and probes your answers, so you get used to the pressure before the real interview.
• Follow-Up Questions: The AI asks follow-ups and pushes back on weak answers instead of reading from a fixed question list.
• Real-Time Feedback: You get instant analysis of each response, suggestions for improvement, and a performance score.
• Scoring After Every Answer: Each answer is scored, so you can see exactly where you are strong and where you lose points.
• Screen Sharing in Sessions: Live interviews support screen sharing, which helps you rehearse technical rounds the way they happen on real calls.
• Multiple Round Types: Practice intro, technical, and leadership rounds so you can prepare for the full interview loop, not just one stage.
• Role-Based Practice: Choose your role first, with current support for Software Engineering, Data Science, ML, and GenAI.
• Simple Credit System: Each interview session costs 1 credit, and credits don't expire.

• Realistic Pressure: Practise with an AI interviewer that challenges your answers and simulates the pressure of a real interview.
• Instant, Specific Feedback:: Scoring and improvement suggestions after each answer show you what to fix right away.
• Practice On Your Schedule: You don't need to book a mentor or wait for a scheduled call. Just start a session when you're ready.
• Flexible Payment Options: Payments go through Razorpay and accept cards, UPI, net banking, and wallets, which suits users in India.

• Windows Only: The product is currently available only as a Windows version, so Mac and Linux users can't use it yet.
• Narrow Role Coverage: Practice focuses on Software Engineering, Data Science, ML, and GenAI. Candidates in product, design, sales, or non-tech roles will need another tool for now.
• No Refunds On Credits: Purchased credits are generally non-refundable, so you should check you have enough credits before you start a session.
• Pay-Per-Session Model: Every interview uses 1 credit, so heavy practice costs more over time than a flat unlimited subscription that some alternatives offer.

• Final Prep Before a Tech Interview: You have a software engineering interview next week and want one more realistic mock. Run a technical round, take the follow-up questions, and use the per-answer scores to tighten your weak spots.
• Practicing Your Self-Introduction: Your opener tends to ramble. Run intro rounds until your answer is clear and concise, using the instant feedback to cut what doesn't land.
• Preparing for Leadership Rounds: You're moving into a senior role and expect leadership questions. Practice with an AI that challenges vague answers so you learn to back up your claims with specifics.
• Breaking Into Data Science or ML: You're switching into data science, ML, or GenAI and haven't done many interviews in the field. Use role-based sessions to get comfortable with the format and the pressure.
• Building Composure Under Pressure: You know the material but freeze when an interviewer pushes back. Repeated sessions with an AI that interrupts and probes help you stay calm and think out loud.
