Crowding on a Tokyo rail platform

The prompt
A Tokyo rail operator has dangerous crowding on one station platform during the morning peak. How would you think about fixing it?
Candidate-led: there is no framework for this. You build your own flow model and ask for the numbers; the interviewer answers and challenges.
Practice with a partner
1. Send the interviewer link to a friend. They read the case aloud and hold the answers.
2. You open the candidate view: you see only the prompt, a timer and a notes box.
3. Speak the case out loud. Your partner shares data when you ask, then scores you with the rubric.
