Interviews almost always involve a spoken conversation between two or more parties, but can also happen between two persons who type their questions and answers.
Interviews can be unstructured, free-wheeling, and open-ended conversations without a predetermined plan or prearranged questions.
It is a flexible arrangement in the sense that subsequent questions can be tailored to clarify earlier answers.
Interviews have taken on an even more significant role, offering opportunities to showcase not just expertise, but adaptability and strategic thinking.
Each of these practices allows the interviewer, or researcher, the opportunity to use their bias to enhance their work by gaining a deeper understanding of the problem they are studying.
