I'm OP of this thread:
https://www.dcurbanmom.com/jforum/posts/list/1115774.page
I was cold applying to remote jobs and jobs in cities far away where I didn't have any obvious connections (although I naturally had personal reasons for selecting them). I think I count as midcareer, though? I've been out of school/working for ~10 years.
Every company I get interviews for to did fully remote interviews as a matter of course, if that's a concern.
Tl;dr of my thread is that I submitted 28 cold applications, got 5 interviews, and 3 offers. Timeline was roughly 3 months.
