I like how easy they make your life as an employer! They have so many options for each stage of my candidate's application/interview journey which makes everything run much smoother than before when we had multiple applications coming at me every day (and sometimes several times per hour!).
There is nothing specific about this tool but there are enough bells & whistles built into both sides' experience - if one side doesn't work out then another can be introduced without too big of changes needed by either party. It has made finding qualified applicants very quick since most people look through these sites first anyway looking specifically towards jobs posted within those fields; however not everyone will fit perfectly well even after going though 3 interviews over 2 days because some just aren’t cut out for certain things such as coding.
