Great question. Been in a similar situation myself. This may sound a bit obvious, but for the "tell us about yourself" question, focus on exactly what has been mentioned. They do say that you can go outside this scope, which is great, but I would personally start any answer by referencing one or more of those mentioned elements. There’s no need for an intro as it’s just 300 words and will eat up your word count, but starting with a thesis-like statement will help. So, for example, “I have taken part in many extracurriculars at university” – then you cover those in that little paragraph. Then move onto the next element and do the same in another paragraph. It’s not necessary to do this, but it helps with structure.
Another thing is that it is great you’ve listed some of these things in the work experience section, but remember that you may not have been able to touch on it in depth. In my opinion, the word count will never be fully enough to expand on these in the depth your application needs to bring it to life – and the additional question is giving you an extra green light to shed light on these even more. So, take your time with ensuring that you don't just
“list”, but also expand and link to its relevance to the trainee role at
Macfarlanes and their values. I remember once approaching a question like this by referencing skills, how I demonstrated them through past experiences, and then mentioning speaking to trainees at the firm who said XYZ, reinforcing my desire to train there. So, there are many ways to approach this question with whatever you choose to elaborate on. Just ask yourself: is it true to me, and does it sound convincing enough?
And yes, definitely worth highlighting those achievements!
Also, contrary to popular opinion, personal interests are actually really valued by law firms, but perhaps touch on those other main things at this point given the word limit, and shed more light on the personality-related point later down in the application stage if the needs of the situation demand it.
