Why Spoken Mock Practice Beats Silent Flashcards
In a real interview, your brain has to retrieve concrete metrics, structure a Situation-Task-Action-Result arc, monitor the interviewer's expression, and wrap up in under ninety seconds—all out loud. Practicing exclusively in text hides verbal crutches and 3-minute tangents.
Running the `Interview` template in GPT Realtime Assistant lets you watch your own words appear in the side-by-side transcript while the assistant pushes back on vague claims ('What was your individual contribution vs the team's?') just like an experienced hiring manager.
Important Ethical Note: Practice Beforehand, Never Circumvent Rules
GPT Realtime Assistant's `Interview` and `Coding Task` templates are designed for **mock rehearsal, study, and consented hiring debriefs** (`Hiring Debrief`). Always follow employer assessment rules and recording-consent laws during real interviews—authentic preparation beforehand builds genuine fluency that no shortcut can fake.
