Draw a qualitative interview study design diagram with Mermaid flowchart TB syntax. Define the research question, review literature and choose a theoretical lens, sample purposively, write the interview guide, pilot and revise, conduct and record interviews, transcribe verbatim, do initial coding, and group codes into categories. If saturation is not reached, return to sampling; if reached, develop themes, do member checking and peer debriefing, write up findings, then discussion and conclusions. Use a diamond for the decision and no parentheses in node text. Output only the mermaid code block.
