This may be true, but it's hard to get a sense of why you are or are not getting hired / getting interviews from the job-seeker's perspective, since you are not really privy to the decision-making process and can't really trust that the reasons given for them not hiring you are the real reasons (generally they don't owe you the truth and strategically it's often better not to say anything or to give some mundane reasons).

I've been involved in a small number of interview processes from the hiring perspective, and I've definitely seen some concern regarding job-hopping where it could easily make the difference on a marginal candidate. That said, this is only at one team in one company - and I was not involved in the initial resume screens (where people with a lot of job-hopping may have been eliminated entirely before I ever saw them). Probably would be best to get a broader perspective from people who have a lot more experience with hiring.

Indeed. I added my anecdote as a data point for arguments for being ready with a good explanation as to why you've left your previous employers.

Either they care and they don't call you, or they don't care and they don't ask.

In my experience the number of employers that don't care and don't ask are sufficiently large enough to not be concerned about the former employer type, especially for someone looking to get out of an uncomfortable employment situation.
