In addition, says Schade, getting any company to provide more information than what it already voluntarily provides to applicants could be a tricky business.
"I'd be interested to see most of all what [eHarmony] can do that is innovative or different from what's out there," he says.
There's also the problem of how companies will portray themselves so as to not scare away potential employees. Employers may not like answering the dreaded "What's your worst quality?" question that is typically asked in job interviews (especially since "I'm too much of a perfectionist" doesn't work for a corporation the way it does for an interviewee).
Warren, however, believes that evidence of results, backed up by his well-known brand, could convince companies to be more forthcoming. He explains how he would pitch it to a reluctant firm: "If you could be fed people who are really great matches for the job you have, and their productivity was provenly higher because the match was so good, would that make it worth your while to give us a significantly more personal, private information about your culture and the people within your culture?"
Proving that its job-search system can create higher productivity is a lofty goal for eHarmony, and it will be hard work. But marriage is hard work, too, and the company believes that a successful track record in the romantic realm can translate to the labor market.
"We would like to be able to help people in jobs at the end of five years, seven years, 10 years, or 20 years, to be able to say, 'This was a perfect match of a job for me,' " Warren says.
