Is being on a journal really worth it?

I’m currently thinking about doing a journal during my 2L year and want to hear from people who’ve done it if it’s really worth it or if it’s more work than it’s worth? If I can, I’d prefer to work during the semester but if that’s not feasible is a journal something worth doing? What are the pros and cons of a journal? Do I absolutely need to do one to secure a good job post law school?
