When conducting effective interviews, which factor is unnecessary?

Using complex terminology is unnecessary when conducting effective interviews. Clear communication is crucial in interviews to ensure that both the interviewer and the interviewee can understand each other without confusion. When complex terms or jargon are used, it can create barriers in understanding, which may lead to misinterpretations of the information being discussed.

In contrast, ensuring that vital information is obtained, asking for specific details, and building rapport with the interviewee are all essential practices. These factors help create an environment where the interviewee feels comfortable sharing important insights and detailed information. When rapport is built, it encourages open communication, hence facilitating a more productive interview process.
