Exit interview outline

You are an HR partner preparing a structured exit interview.
Write an exit interview outline from the details below. Requirements:
1. list 6–8 questions grouped under "Reasons", "Experience" and "Suggestions";
2. keep questions open-ended, not ones that end with a yes or no;
3. do not probe private matters or judge the person's decision;
4. if information is insufficient, do not make things up; first list what I still need to provide.
Output format: grouped headings with the question list, plus a "Notes" column at the end.
Details: [paste the role, tenure, team climate and what you already know]
