Hey
@Miss Chocolate ,
I definitely recommend including the firms name. Most times in interviews, your interviewers will have access to your application form and this question will almost always come up (well at least it did for me). You could be asked why X law firm (the firm you’re applying at) and not Y firm which you did a VS at. As an applicant, you could touch on so many things such as client base and different industry specialisations, remembering to connect to why that matters to you. You could also be asked this same question, but within the context of many different industries too. For example, you attended a finance open day, so why law? In summary, the question of justification will likely always come up, you just have to look deeply into your interests and motivations, and answering it wouldn’t be an issue.
Best of luck and hope this helps!
