The big problem with sourcing data from consumers that only have a temporary need for the service is that the average user isn&#x27;t going to diligently update the system with all the feedback calls and emails they receive <i>after they&#x27;ve accepted a job</i>...<p>I suppose you could automate the data update process to the extent that commercial ATS vendors are willing to link up with your system via API. There are even job boards that send notifications when someone views your application, though as a candidate I&#x27;m not actually sure whether that makes me more or less concerned about not getting an email back from them...
