I frequently help my clients identify companies which could help them recruit new employees, and manage that process. We all know about LinkedIn, Indeed, ZipRecruiter, iCIMS, and other major players. However, this space is changing quick and I frequently get questions about new comers like Hirevue. I am looking for good resources that can help me keep an eye on new comers, and ones which are maturing, delivering results, and getting market share. If you are in that space, what resources or companies would you recommend keeping an eye on? In general, how do you anticipate that space changing in the near future?
