What type of questions are typically asked in an in-depth interview?

In-depth interviews are primarily designed to gather rich, qualitative insights into participants' thoughts, feelings, and behaviors. Open-ended questions are central to this approach because they encourage respondents to elaborate on their answers, providing a deeper understanding of their perspectives. This type of questioning allows interviewers to explore complex topics and obtain nuanced details that closed-ended or multiple-choice questions may not reveal.

In contrast, closed-ended questions typically yield quantitative data, which is less effective in an in-depth interview context where the goal is to explore deeper insights rather than merely collect statistics. Multiple-choice questions also limit the scope of responses, potentially missing out on valuable qualitative data. Direct questions for demographic profiling focus on specific characteristics rather than the in-depth exploration of views. Thus, the use of open-ended questions is key to achieving the objectives of an in-depth interview, making it the correct choice here.
