Good question! We usually recommend to submit a fully complete logical part, e.g. auth middleware, client, server. We recommend against submitting incomplete functionality in a PR because it is hard for our interview team to understand whether it's incomplete or complete and has defects.

so would each complete logical part be a separate branch with its PR ? and then branch from the previous branch to create the next PR?

I'm just wondering if you found there to be any cognitive overhead here.
