Details operates by first allowing users to start a mock interview through its platform, emulating real-world interview scenarios. The platform provides instant feedback on user responses, breaking down areas of strength and opportunities for improvement.

Users can repeatedly attempt various system design questions, such as designing load balancers for Apple Music, and receive tailored hints and feedback from AI. This process helps candidates practice consistently, thereby reducing the likelihood of flunking real interviews.
