Practice that watches itself

Interview preparation asks for a different kind of honesty than a course does: not “did you understand this,” but “can you say it out loud, under a little pressure, in the time you actually have.” The interview surface runs a practice session against a stated role and topic, and gives feedback grounded in the same material — your own notes on the subject, not a generic bank of interview advice.

The design choice worth naming is that this tool shares an engine with the learning surface and the conversation surface rather than reinventing its own separate model of what a good answer looks like. Practising for an interview and studying a subject are, underneath, the same act — retrieving what you actually know and checking it against something real — and the environment treats them that way rather than as two unrelated features.
