thanks your interest in this topic! I mean the quiz makers for which the main purpose is to check knowledge and skills in use cases such as hiring, customer service / sales team trainings, or compliance with standard operating procedures. Engagement is not always the primary reason to use quizzes. Sometimes it is more geared towards identyfing strenghts and weaknesses of an individual or team, that allows to improve or make better decisions.
