No, I don't think you need to add that this is a core skill the firm looks for in its trainees, as this will be known to those reading your application, and you should aim to make the most of your word count!Good morning,
When drafting work experience for law firms app. Is it always better to specifically tailor it ( highlight a core value or skill the firm needs and mention how it is related to your experience) e.g ‘I have developed communication skills through… which is a core value that is valuable to xxx firm.’
However, if there is a specific way in which your skills matter to the firm, this may be worth emphasising! For example, for firms with very small trainee intakes (1-8), I found myself emphasising how my experiences as the only junior member of the team would assist me, and therefore I specifically pointed out that a very small trainee intake at XXX firm would mean that I'd often be the only junior member in their teams
In general, though, you won't need to state something like "Attention to detail is a core skill for a trainee at XXX" firm. Only provide an explanation where you think the link is not clear without one!
