I just applied for any engineering management position. They asked in the application submission process, "Tell us about your biggest achievement or personal success in customer support".
Personally, I think it's nice to have a space just for that sort of question, pre-interview, that doesn't take up space in the resume or in the cover letter, so I appreciate the question. This is what I said:

It doesn't take much effort to find examples of truly deplorable leadership in the present (and it's a slam dunk if you take the historical route). Today, I encountered a LinkedIn article and an NPR radio program that centered around the idea of toxic leadership, so it seemed like an obvious choice for a topic, especially considering how many toxic leaders I've encountered in my own career.
