In-depth interviews are informal one-to-one discussions conducted according to a well-structured discussion guide, encouraging respondents to engage in detailed and reasoned conversations on topics relevant to the research objectives. They are used to define the research problem, propose hypotheses, and identify key indicators prior to quantitative research. Due to the limited number of respondents, the results cannot be generalized to the entire population.

Interviews are conducted one-to-one, without the presence of third parties, and typically last between 30 and 60 minutes.

The project usually involves no fewer than 20-30 in-depth interviews.
