I've seen a lot of new-to-remote engineers get themselves in trouble with this. The ideal case is that you can just work whenever and submit/review any PRs asynchronously. What happens instead is that they hit a problem and are blocked or spinning their wheels at 2am because nobody else is awake to help them. Alternatively, they toss something over the fence, disappear, and their work is useless for another full day until they address a comment or last-minute issue.
