X-Hi-Human
loreAirbnb's response header greeting whoever reads it, with a hiring address from the Production Infrastructure team.
Troy Hunt's March 2015 survey of recruitment messages hidden in sites found Airbnb answering with X-Hi-Human: The Production Infrastructure team added this header. Come work with us!, followed by an engineer's hiring address. It sits with X-hacker in the recruiting branch of the genre, and it is the friendlier of the two: a greeting first, the offer second. Hunt's point in collecting them was that the people who deconstruct a site to see how it is built are precisely the people worth reaching, and a header reaches them at the moment they are paying attention.
