The CV parsing feature is the most valuable. It can parse resumes for the database. It is easy to deploy, and it is also stable and scalable. Its support is also good.
The feature that I have found most valuable is the interview schedule piece. This allows me to see what interviews are going on. It allows me to put them on my calendar and to track that piece so that I can follow up both with my candidate and with my hiring manager.
The scheduling function was the most valuable. All dropdowns and options for scheduling were good. It was pretty user-friendly at the time and had all the bases covered with the dropdown options.
