A one-on-one interview is a direct, personal conversation between a journalist and a subject, typically focusing on gathering detailed information, insights, and quotes for a story. This format allows for a deeper exploration of topics, enabling the interviewer to ask follow-up questions and clarify points in real-time, resulting in richer content for the audience. The personal nature of these interviews helps to build rapport and trust, often leading to more candid responses from the interviewee.
