I like how easy it was to create an account, search for jobs in my area of expertise (veterinary medicine), apply directly through their website or mobile app, receive notifications about interviews/offers etc., see where they stand at any given time by looking up your status online, read job descriptions before applying so you get better prepared when interviewing! Nothing really but maybe some more features would be nice such as being able to upload curriculum vitae instead of having to link from another site or just putting them right into applications? Also sometimes there are glitches during application process which makes things difficult if not impossible.
It's helpful to have access anywhere even outside work hours since working remotely can make finding applicants easier than trying to find someone locally who works similar shifts.
