Well, I'm not sure this is worth the effort - even before the AI era I am skeptical that anyone with half a brain would be in charge of reading the responses from rejected candidates. Brains and even half-brains are a rare resource in any company, it wouldn't be efficient to let them waste time reading the answers of rejected candidates. So if the answer is read at all, it will be read by someone thinking about her mother-in-law or her next vacation destination, not about her sh*tty HR job sending rejection letters and (sometimes) reading the replies. If my assumptions are correct, is it worth wasting time replying at all?
