Hello!
On your first question: I think it’s totally fine to combine the action and result into one sentence or short paragraph, especially in a short work experience section where space is limited. Something along the lines of ‘I drafted X document, which was later used in Y’ is clear and efficient, and shows the impact whilst making the most of the space.
In relation to including skills, I’d say that this is definitely firm dependent. I would follow the advice that the
Willkie graduate recruitment outlined for their application (as that will reflect what they are looking for). Some firms will prefer a very factual, CV-style approach whereas others are more open to candidates discussing key skills. The key is to keep it relevant and realistic, such as your example about juggling an internship and studies to show time management - that is a solid, credible link.
I would say that as a general rule of thumb (unless otherwise stated), I would link key transferable skills if they are relevant, but try to not overdo it. Firms will want to see that you know what skills trainees need and that you can demonstrate how you have them, but I wouldn’t try and force a connection that isn’t there.
I hope that helps!
