It'd be easy to dismiss this all as some big joke, but it turns out the listing is legit. According to Richard Conway, the founder of the site Childcare.co.uk where the listing was posted, they did some digging to ensure it wasn't some elaborate hoax.
"Some of the guys at HQ were skeptical but after talking to the family and their previous employees we realized it was a genuine position. We have hundreds of thousands of providers on the site and we’re hoping that one of them will be able to help them," he told the Mirror in an interview. "The family has assured us that no harm has come to anyone living in the house, however the nanny will have to have a strong disposition!" So, like, a hearty Mary Poppins type?
It turns out a number of brave souls are interested, after all. The family just posted an update to say they've been overwhelmed by the response, and have already received over 2,000 messages related to the position since the listing went up a couple weeks ago. It couldn't be any worse than some of these crummy entry-level gigs, right?
