Final answer:
The statement is False. A formal interview involves a systematic process with predefined questions, unlike the more spontaneous and adaptable unstructured interview method.
Step-by-step explanation:
False. A formal interview is not an unsystematic method where the interviewer decides on questions as the interview progresses. By definition, a formal interview requires a systematic approach, with all questions and their order being predefined to ensure consistency across all participants, thus maintaining a systematic approach.
On the contrary, an unstructured interview is where the interviewer might adapt questions based on the response of the interviewee. This allows for a more spontaneous and free-flowing conversation but is not the method employed in formal interviews. A structured interview involves asking all candidates the same prepared questions in advance, enabling a standardized and fair evaluation process. Unstructured interviews have their place in qualitative research and certain job or college admissions contexts but are distinct from the formal, systematic interviewing process.
