Useless list. This will be the 57th priority in the list of things that one would be worried when looking for a job.

i) If you are unemployed, you really don't have a choice.

ii) If you are talented and sought after, trust me you won't be ghosted.

Ghosting could be just one HR person or an orgs incompetency. To project that to your career prospects in that said company is completely irrational.

Not to mention without doing real statistical analysis, like total ghosts / total interviews by month.

Or how about gaming this list itself?

This list is for naive, populists who think that this matters.
