In an exit interview I've done, it was clear to me that HR was trying to spin a story about why I was leaving that didn't align with what I was saying or trying to say. They were nice enough, but it was full of questions that appeared to be designed to invalidate my thoughts or feelings. For example, the question: "But did you have the resources you needed to do your job?" to my point of "I felt like I was set up to fail on these projects."
They also focused on single points that were actually just a small part of a much larger picture, emphasizing them as though to suggest that they were the singular reason for me leaving. It was a frustrating experience, and it felt dishonest. I felt like they didn't want the real reasons I was leaving, they wanted a story that didn't make the company's processes and management look flawed.
