It's not about managing. It's about the friction to reaching out for help and lost productivity from having to schedule meetings combined with inexperience making it hard to decide which problems are worth the friction of reaching out and which ones aren't. There's also the sense of isolation that being remote gives, because asking for help over a private message makes it look like you're the only one that needs help. All of this is still a problem regardless of clarity of expectations and tasks.

My preferences are likely going to change once I get more experience under my belt but I absolutely feel there are some facets of remote work that benefit senior engineers at the expense of junior engineers.
