Sure, a new job would be great, but you lack the time or motivation to search hard for one. Good news: you are what recruiters call a “passive candidate,” someone who is already employed but dreaming, at least idly, of other opportunities.

Passive candidates are the prize ponies of the recruiting world, and a slew of new services have sprung up lately to connect those passive candidates to companies interested in poaching them.

Like online dating services, the new sites and mobile apps use questionnaires and algorithms to match workers with companies. All are designed so that workers can indicate they’re open to new jobs without their current boss knowing. Job non-seekers can use them for free, and employers pay for postings or leads.

Poacht imports employment information from a person’s LinkedIn profile, save for his or her name, photo and contact information. Poacht asks users how serious they are about switching jobs, whether and where they’re willing to move, and what salary they’re seeking, among other questions. The app notifies candidates when an employer’s interested in an interview.

Switch, which works like the online dating app Tinder, suggests jobs to users, who then swipe right if they’re interested and left if not. User profiles are anonymous—only when both parties express interest does the site reveal the user’s real name and contact information. Switch, launched last summer,says it avoids presenting candidates to hiring managers who work at the same company. Mobile app Jobr works also allows workers to swipe left or right on jobs that interest them.
