Honestly, two years of law review including a top editorial position your third year is a good way to take what can be a relatively chill couple years and turn them into much more work. I didn’t make our main law review but was eventually EIC of another journal, and that was by no means easy sailing.
In the end I was able to get a federal appellate clerkship, and I do think I got a lot out of both of those experiences (EIC and clerking).
But was any of that necessary to having a great legal career? Definitely not.
