Hello-I'm having an issue where someone who is assigned as a passive user is not showing up on the list as able to interview a candidate?  Any ideas why this is happening?  They were assigned the out of the box Passive User with no changes.

Is there a different user role I should be using for the employees who are just interviewing candidates and submitting feedback?
