1. Specify the goal of the interview and select questions and subjects around the topic carefully.
2. Define if there is a need for a structured interview or semi-structured interview. Structured interviews have a clear guide that needs to be followed, semi-structured interviews allow for flexibility within the interview.
3. Conduct a pre-interview during the recruitment phase, to refine the guide.
4. Talk, watch, listen and observe as you conduct the interview.
5. Document the interview by recording audio/video (if possible) and take notes.
6. Analyze and compare the information gathered from the interview(s).
