They can also be hard to find because they won't be advertised as remote. I'm full time remote but this wasn't mentioned in the job description, and I only found out after getting the job offer. I think management had the sense that advertising the position as remote attracted "the wrong kind of people".

I guess technically I have an "unlimited work from home" policy, because I do still have a desk if I want to go in.

I think there might be fewer people who actively seek them out, so competition might be similar to any other job. I know a common sentiment I see spread around to would-be remote workers is that you need to work on-site for a while and then be given the chance, which isn't always the case.

This is just me speculating though. I had no issues finding a fulltime remote gig but I think it might be more common for people like me in the DevOps/cloud area than strict developers maybe.

I would love an answer to this as well.
