This has been an issue at my org and we're having a hard time improving it.
Maybe a better online solution would help, a-la some magical VR space that Meta comes up with.
Remote working requires effort too.
Whether they are remote or in the office, they can be successful. If they are getting their deliverables in on time and do things the way they are asked to do them (follow these simple rules)... that's all that matters.
And when I say follow the rules, I mean that I don't care if they use vim, emacs, nano, Wordpad, Windows, MacOS, Linux, etc. But I do care about how they submit a merge request and whether or not they PGP sign their commits.
Biggest pain point was the flexibility that was required with lockdowns meant sometimes the senior members were occupied with parenting responsibilities but we tried to ensure that the junior member had someone to pair with most of the time.
