The candidate overheard a conversation between HR and their manager. Then came a second interview. Then an offer, extended on the spot.
What was said in that conversation is not recorded — but the sequence is: an overheard exchange, one more interview, and a hire with no waiting period. No follow-up email, no "we'll circle back," no committee. The whole apparatus moved at the speed of people who were allowed to decide. It is not a complicated recipe. It is just rarely permitted.
