The British royal family has a distinctive approach to hiring housekeepers, famously utilizing a 'dead fly test' to evaluate candidates' attention to detail. Tracey Waterman, head of staff recruitment, explains that she hides a dead fly in a royal room, expecting applicants to notice and dispose of it. This test highlights the difference between a housekeeper in a five-star hotel and one in a royal palace, with only about 1 out of 10 candidates successfully picking up the fly. Those who pass the test gain access to royal residences and enjoy various perks, including 25 days of annual leave and a salary of £24,188 ($32,000) annually. While prior cleaning experience is not mandatory, candidates must demonstrate a proactive attitude, good time management, and utmost trustworthiness. Working for the royals may not lead to wealth, but it offers a unique lifestyle and the chance to interact with senior royals.
