Every meeting needs three things: an agenda, a decision to be made, and clear action items at the end. If you cannot define these, it should be an email.
Strong answers: clear agenda shared in advance, right people in the room (and wrong people excluded), time-boxed discussions, active facilitation, clear decisions and action items, and follow-up. Best candidates also mention when to cancel meetings, when to make them async, and how they create space for quieter team members to contribute.
Reveals organisational respect and efficiency. Leaders who run bad meetings waste enormous amounts of collective time. Ask: "What percentage of meetings on your team could be emails?"
