Help needed: what type of goals you'd set for the upcoming perf review when you're less than a few months in a company?

It’s kind of weird to even have a perf review so soon... but I guess they’d mostly be about onboarding (getting to know the codebase(s), getting to know the processes, coworkers etc). And then if you’re supposed to set goals for a whole year or something... well, hard to say, at least with this little info.
