As a hiring manager I take candidate experience seriously because I know it’s easy to get wrong and leave people with a really bad taste in their mouth at a sensitive time.
As a candidate, though, I have learned not to take offense to being ghosted or the million other indignities that one is subjected to in a modern interview pipeline. It’s just a part of the modern economy, and far from the worst one. As terrible as it is, it’s not a hill worth dying on, suck it up and just move on with your search.
