A structured interview is typically planned, the interviewer usually has a set of determined job related questions and a scoring system. On the other hand a non-structured interview is less organized with no preselected or scoring system. In this method the interview process is unplanned so the conversation can go on a tangent or be biased. Based on the natural flow of non-structured interviews legal issues can occur, that is why it is important to conduct a structured interview instead. With a structured interview questions can be checked for legality and relevance, which can help stay on topic and avoid potential discrimination. Having a scoring system can also help avoid bias and claims of discrimination. For more on structured and non-structured interviews, see
