I like that it's easy for employers/employees alike! The system works well in finding referrals from people who are currently working at my clients' businesses or have worked with them previously - there really isn't anything too much i dislike about this program as of yet but if you're looking into using any type of job search site then make sure its compatible because some aren;t so good when searching through certain sites (like Monster).
It makes things easier than having your own database filled up by yourself!!
