Role plays test how candidates might approach difficult situations that frequently occur in the business world. Interviewers frequently ask interview candidates to assume the role of a specific company employee and ask them how they would approach a hypothetical or real life situation.
Often one of the interviewers will act the part of a member of the public, colleague or customer and another interviewer will watch and take notes/assess you. The situation will often involve some sort of controversy or conflict or dissatisfaction on the opposition's part, and require negotiating and reasoning as well as customer service skills from the interviewee.
a little bit more detail would help, as this article is very short. Can someone expand this please, thank you.
