The online employment service Jobaline.com doesn’t really use the face-to-face interviews, but rather feeds research and algorithms into a computer, which then judges candidates based on how their voice sounds. There are, apparently, different choices for different voices.
Salazar says your voice has a certain subtle signature that sounds different – even if it‘s ever so slightly – when you’re happy, sad, mad, or in a hurry, and the algorithms interpret all those subtleties as it makes a match.
Salazar argues that the Jobaline “secret formula” can even pinpoint if a voice is calm, trustworthy, and engaging, which can be very important for certain kinds of jobs, such as in the hospitality business.
More and more companies are using this kind of system to help them sift through applications. Humans make the final judgement, but that algorithm helps the companies narrow down the pool, cutting down on time and costs.
