How do I start with the AI interviewer?
Select the orb to open Caselane’s account entry, then choose an available interview in the app. AI practice requires an account and is subject to your plan’s access and usage limits. This page does not start a microphone session.
Is the free example the whole case library?
No. The free coffee-chain example is one original fictional practice scenario you can read here. The case-library link takes you into Caselane’s account flow, where you can explore the library available to your account.
