To conduct reliable interviews for research, there are several important requirements that should be followed:

Clear research question: The research question should be clearly defined before conducting the interview. This will help ensure that the questions asked during the interview are relevant and will provide useful information.

Adequate sample size: The sample size should be large enough to ensure that the findings are representative of the population being studied. This will help increase the reliability of the results.

Standardized questions: The questions should be standardized to ensure that they are clear and unambiguous. This will help ensure that the responses are reliable and can be compared across participants.

Ethical considerations: The interviewer should adhere to ethical considerations, such as obtaining informed consent from participants and protecting their privacy and confidentiality.
