I like that it's easy for me as an applicant or recruiter/hirer because of its mobile-friendly interface! It also has great analytics so we can see where our applicants are coming from (which is very helpful when trying to target them).
We've had some issues with their customer service team but they have been quick at responding and fixing things up quickly once contacted about any issue you may be having. Great platform if used correctly; however, make sure there isn't much competition in certain areas within your industry which makes searching easier than others.
