Congrats on the interview!
Honestly, I have seen both cases, with and without "classical" case -when it hapened, it was mostly focused on the strategy part nad not so much the details and numbers.
Same goes for some content-related questions or mini-cases, I have seen it both happening and not.
I know it´s not something that helps you narrow the content to cover, but unfortunately, I think doing that would be a mistake.
Furthermore, you need to pay a lot of attention to the FIT interview, it becomes particularly relevant in these tenures.
Hope it helps!
