We're fully remote and regularly hire people with remote work experience. However, it is important that our team members are self managing and we do ask questions about that during the interview.

Sure, the only thing I can point to is side projects (see I can be productive when noone is watching!), but that's not the same, I suppose. I'm an introvert and live inside my own head anyway.

Problem, the industry I work in (defense) doesn't do remote, for obvious reasons.
