Hi!
No problem at all!
I'd say that you don't have to explicitly link every competency answer back to commercial law, but adding a short reflection at the end can strengthen your answer if it feels natural. For example, after describing your teamwork example using the STAR method, you could add a brief sentence at the end such as:
"This experience showed me the importance of clear communication and collaboration, which are skills that are essential when working in legal teams and managing long-term client projects"
This keeps your answer focused on the original question while subtly demonstrating awareness of how that skill is useful in the legal context. The key is to keep it short and relevant - I would avoid turning it into a long discussion about what skills are generally valued in law.
If the link feels forced, it's better to end confidently on the outcome of your example instead. However, if you can fit it in relatively seamlessly, the reflective line can show commercial awareness and self-reflection!
I hope that answers your question - you're definitely thinking about this in the right way!
