Final answer:
Interviews focus on the exchange of questions and answers, and while social factors and body language can influence them, they are not essential for an interview to occur.
Step-by-step explanation:
Most definitions of interviewing do not include social factors and body language as a necessary aspect of the process. While these factors can influence the outcome of an interview and provide additional context to the interviewer, they are not deemed essential for an interview to take place. Interviews center around the exchange of questions and answers and this core component is required regardless of the presence or observation of social cues or nonverbal behaviors.
