Someone who talks to people all the time about what they want is a twenty-six-year-old woman I'll call Claudia Gomez. She is what is known in the headhunting trade as a "ruser," meaning one who performs ruses, one who uses surreptitious methods to trick receptionists into giving out names and job descriptions of employees at Silicon Valley companies. She sells these names to research firms, which in turn sell them to headhunters. So hot is the black market for names out here that Claudia gets $40 for a salesperson and $80 for an engineer, and for a female engineer she gets $120, since every company wants to improve its diversity.
