My experience (as an employer/customer) with this outfit (jobvite) was like time travel back to 1998 or so--not retro in a good way though. First, the custom "candidate reports" delivered to us were often poorly parsed versions of the actual candidate CVs. Second, the have no interest in aggregating information from community resources (linkedin, StackOverflow, SO Careers, etc.) nor even in allowing a candidate to include their accounts on those Sites. And finally, because the candidate contacts the company via jobvite, when the interested employer replies via email, it's likely to get flagged as spam or ignored because there is no email in the candidate's outbox with this email domain (this seemed to happen about 25% of the time to us).
