Who uses the phrase losing the room?
Prept uses it for the moment in a recorded interview where an answer drifts and the interviewer stops building a case for you. Its debriefs quote that moment back from the transcript, with the time it happened. Candidates use the phrase the same way when describing a call that turned partway through.
What does losing the room sound like?
For example, here is an invented exchange, written for this page and taken from no real interview. The interviewer asks, "Roughly how much did that save?" The candidate says, "I'd have to check," then spends a minute on the project's history. The interviewer says, "Okay. Let's move on."
The missing number is where the room went. The minute of history afterward made it harder to win back.
