To clarify, I probably have at least 30 different questions that I've answered in application forms, and the specific application questions for the VI (Fox Williams) I'm preparing for were:
1. why should we select you? what sets you apart from other candidates?
2. which of our core sectors appeals to you most?
3. impact of AI on the law.
So I therefore have quite a few personalised answers to questions such as "what's your proudest achievement" that I've given in written applications, that they wouldn't have read/heard before.
They've said that there are "three very different questions", which will "test your research into Fox Williams, your communication skills, and about you as an individual"
So the first part of that could be
"why do you want to work for us" or
"what sets us apart from our competitors"
and then the others could be anything, e.g., "tell us about a time when you have had to manage difficult people", "tell us about a person who inspires you", etc.
I think in this case it would probably be fine to use application form answers as the foundation to answers in a VI, but it would be better to provide more detail or expand on the points made. There is a post that @Andrei Radu made recently on the forum which I think answers this question, so I have quoted it below: 🙂
I do not think there is any issue with having an interview answer that mirrors an application form answer. I actually have no idea why this has become such an almost universally accepted myth - I personally never saw an issue with using the same reasoning as in your application. In many cases partners will not even review your application in any level of depth before the interview, and if they do, they will not as a result form an expectation for you to come up with a different reasoning as to your motivations, or skill set, or to use different (and less directly applicable) examples if asked the same question merely for purposes of variation.
They will simply expect you to answer the question in the most accurate and convincing way you can. This might necessitate some changes to the application form answer, both because the communication format is different, and because you might want to have a more nuanced/detailed analysis in view of potential follow ups. However, the main themes and ideas should likely stay the same. If anything, it would likely look somewhat suspicious if your fundamental motivations, skills and most relevant experiences were to all of a sudden be very different from the ones mentioned in the application form.
