I ask as I am back in the market, and have had 3 companies ghost me (2 from HN who's hiring) after either a couple of calls or for 1 I did a small "test" project (which I almost always refuse but this one was reasonable and very specific plus easily time boxed to an hour or so). I ask as I have not been in the market applying for positions in quite awhile. I have generally been the hiring person for the last > 10 years, minus going from founder to employee 5 years ago. Even then that was only the second company I talked to that time so never got ghosted. I am not claiming I am perfect, there were people I never got back to as well, but it was a tiny fraction of people we interviewed, so just curious if this is common today; if not I guess I need to figure out what to adjust.
