I sit down with juniors and sketch out designs or code for them while talking through the thought process at least once a week, and even when solo coding, I expect everyone produces work that explains itself. For particularly complex/nuanced changes, people do hop on a call to talk through it.

Like I said the deadlines work for both sides. If a company wants to give homework instead of having their own senior engineers spend time talking to me, that tells me what I need to know about how they value my time.
