It’s a good question. I’d say the second question is more about identifying what differentiates
Ashurst, whereas in your cover letter, you’ll be drilling down on why you are personally applying to the firm.
You’re right though, there is likely to be some overlap, so you may want to answer the application question first. I’ve seen a fair few
Ashurst applications that only briefly reference to the firm - as it has been covered in the second question.
