What is milk round? How to use in English

The term "milk round" originated in the United Kingdom in the early 20th century to describe the daily delivery of fresh milk to households by milkmen on horse-drawn carts or ice floats in winter. "Round" in this context refers to the route taken by the milkman, which varied from one household to another depending on the distance and proximity. As the practice declined due to the increasing popularity of pasteurized milk and supermarkets, the term "milk round" became a nostalgic memory of a bygone era. Today, it is widely used in British English to describe job interviews and selection processes that involve meeting multiple potential employers or companies, as these processes often follow a circuitous route similar to the milkman's rounds.
