When an interviewer encourages the candidate to give brief answers to maintain the interview flow, he asks which type of question?

In the context of interviewing, when an interviewer encourages a candidate to provide brief answers to maintain the flow of the discussion, the question type being asked is closed questions. Closed questions are typically designed to elicit specific, short responses that are often limited to "yes" or "no" answers or a choice among options. This format allows the interviewer to control the pace of the conversation more effectively and ensures that the discussion remains focused and on track.

Using closed questions can help to quickly gather essential information without allowing for extensive elaboration, which is particularly useful when time is limited or when the interviewer wants to ensure that specific topics are covered. This contrasts with open questions, which invite more detailed and elaborated responses, allowing candidates to express their thoughts in a broader way, which could disrupt the intended flow of the interview.

Leading questions suggest a particular response or guide the candidate towards a specific answer, while problem-solving questions focus on assessing the candidate's analytical and reasoning abilities. In this scenario, the emphasis on brevity and maintaining flow aligns specifically with the characteristics of closed questions.
