The most helpful feature for me was having access to one place where I could do all my research before coming into an interview or even meeting with potential employers! That way there were no surprises because it allowed us (the team) have answers prepared ahead so we didn't waste time digging up information at interviews/screens afterwards as well when talking about our past work experience!! There really isn’t anything i disliked too much either unless you take issue if someone who seems "too nice / friendly - this can be hard sometimes but not always.
If anyone has any problems while working through their onboarding process then let them know they are able talk directly in chat vs using email etc which takes more than likely longer & also leads people away from what's truly important here- solving your hiring needs!!
