the first one is boilerplate copy-paste identical to all your other applications on allhires.
for example
2024-2025 "McDonalds, Blackpool" "Developed customer service skills, dealing with drunken customers"
(etc.) You'd list your jobs and bullet points for the skills developed and notable achievements. There doesn't need to be anything specifically law related here (although if you've done legal work experience you'd definitely included it), and you wouldn't include anything law-related that's not actual work (so no open days, no "I took someone to court")
And the second one is an essay-type question asking you "Legal Work Exposure (eg. open days, vacation schemes, shadowing, or any other work to show your commitment to law)."
That says "exposure", which is more open than "work experience". Although it does say "work", it's clear from "open days", that it's not necessarily formal work, but could include things like commercial awareness events, which aren't work but do share commitment to law. In addition, I mentioned that I have previously successfully filed claims in the county court, helped someone in the employment tribunal, etc.
