i have found the recent crop of SotA LLMs to be extremely useful for the latter few tasks you mentioned. Give it my full, comprehensive CV, as well as a prospective job description, then ask "tailor a condensed resume from the info in my CV to match this job description."

Of course you'll want to review and edit, but it's taken a huge amount of drudgery out of the process, for which I am grateful.

I hate writing job applications, so even if LLMs aren't good enough yet, at least they are a start.

This gives you some structure to start with.
