The ease of use once you get used to it! It's so much easier than using paper applications or other recruiting tools out there - especially with all our recruiters being remote workers these days.
Our admin team doesn't have access anymore (even though they're still needed) since we moved from an internal tool into SFRecruitment Cloud. Their support has been really good about getting us set up as soon as possible when something goes wrong but I think this will always be necessary unless we move away completely. We are able to keep track of each applicant within our system which makes onboarding new employees very easy.
