@Bread I think there’s no set approach here. It could be approached either way. Personally, I prefer prose, as it allowed you to detail the role, outline your responsibilities and takeaways and link it back to a legal career coherently. Whereas, this may be tricky to achieve in list format - it would just feel forced.
Try writing it out in prose, and if you feel like you’re wasting too much words this way (as 100 for each isn’t a lot) then revert back to list format.
Like I said, I don’t think there’s a set approach here - you just need to figure out which way best works for you.
