Strong agree on the remote training being entirely possible. My first dev job was remote (long before the pandemic) and onboarding was not a problem at all.

In fact because you need people to get set up remotely, I find the documentation tends to be better at all remote companies. In-Office companies sort of assume that you can just tap someone on the shoulder if you get stuck so there's more often, in my experience, gaps in the documentation.

I particularly find this a strange claim since open source projects have been successfully onboarding new people remotely prior to there even being efficient ways to screen share/video chat etc.
