Before your next round
A few good
questions.
The essentials, without the fine-print hunt.
Explore the resourcesIs it visible when I share my screen?
No. Both app windows are left out of screen capture and screen sharing, so your CV, notes and account details stay private: when you share your screen in Zoom, Microsoft Teams, Google Meet or record with OBS, the share shows whatever is behind the window, even if you share your entire desktop. On Windows this needs Windows 10 version 2004 (build 19041) or later, or Windows 11, and the windows are also kept off the taskbar and Alt-Tab. On macOS the windows are excluded from screen sharing by the system. It does not hide the screen from a phone or camera pointed at it, so do a quick test share before an important call.
Is InterviewOSLab only for technical interviews?
No. Use the same copilot for finance, consulting, sales, marketing, operations, HR, product, behavioural, and technical interview questions. The role examples on this site are practice scenarios—not separate specialist models or a promise of perfect accuracy.
What makes InterviewOSLab different?
Real-time question understanding, an initial answer followed by deeper reasoning in Deep Mode, and managed cloud transcription support the broader interview workflow. Connected diagrams and code execution are additional tools for technical rounds. Explore the role pages for sample interview questions.
How does Deep Mode show the two answers?
The normal answer appears first. Deep Mode then adds a deeper response in More detail, using the same question and interview context. You do not need to ask again.
Will a follow-up reset my system design?
No. A follow-up modifies the existing design in the same session — for example, asking to add Redis updates the original diagram instead of starting over.
Does transcription work offline?
The customer app uses managed cloud transcription and needs an internet connection. Audio is sent for speech-to-text processing, and generated answers also use cloud AI.
Is there a free trial?
Yes. Eligible new accounts receive 60 free credits on signup — up to 60 minutes of live interview. No credit card required. When your credits run out, choose a paid plan to continue. No automatic subscription. 1 credit = 1 minute of live interview.
Can I use it in any interview?
Use the app for practice and for interviews where this assistance is permitted. Follow the interviewer’s rules and obtain appropriate consent for recording.
