Each type of interview has a different purpose:
• Highly structured and structured interviews may be used in surveys and be processed 
quantitavely.
• In contrast, semi-structured and unstructured interviews are essentially qualitative, 
phenomenological-oriented data collection methods. They enable exploratory 
discussion that help the researcher to understand the what and the how but also to 
grasp and explore the internal dynamics of the research topic.
The different kinds of interviews can be used in a solitary study to expand the reliability of 
the findings. For example, in-depth, instructed interviews might be used in the underlying 
phases of the examination to distinguish subjects and factors. This information could then 
be used to plan a questionnaire or a structured interview to look at explicit subjects and the 
cooperation of explicit factors.
In addition, in the second phase of a quantitative questionnaire, semi-organised or 
unstructured interviews might be used to investigate and to approve the discoveries from 
the questionnaire.
Design of interview
 
Most interviews include composed content or some likeness thereof with differing 
dimensions of adaptability structured into the interview plan (the organisation, composed 
posting of the inquiries or subjects). In an exceptionally organised interview, the plan of the 
meeting would be fundamentally the same as that of questions. The unstructured open-
ended interview, on the other hand, would have no schedule of questions at all. 
Furthermore, semi-structured interview schedules would consist of some closed questions 
with the interviewer having the freedom to ask the participant to provide more details, as 
well as a test of open-ended questions and themes for discourse.
