The features that are most useful for us include automatic scheduling of interviews with candidates in our database (for example after 3 weeks or 6 months) as well as easy access via mobile app - great if you have employees who often travel! Easy setup/maintenance could be improved by having more options when it comes to customising fields etc., but overall I'm happy so far :) It has helped my team tremendously since we started using this platform about 2 years ago.
We use both their candidate search feature along with integrated recruiting tool called 'Recruiter'.
