Hi!
I'd say it's perfectly fine to discuss a deal that is still ongoing, as long as White & Case has publicly advised on it and the information you use comes from reliable, publicly available sources (such as press releases or news articles). The key is to show that you understand the broader strategic and legal context - even if the deal isn't yet complete.
If details about "how the firm navigated the complexities" are limited, you could instead focus on what the firm likely had to consider or manage, based on your understanding of similar transactions (e.g. cross-border issues, regulatory approvals, financing structures, or industry-specific risks). This shows your commercial awareness, and how you analyse problems!
However, you may find it easier to discuss a deal that has already been completed, as there may be more information online about how the firm navigated the deal and what the particular challenges or considerations were. That said, I think it can work either way - I'd discuss the deal that interests you the most!
In terms of structure, addressing around two to three of each usually works well - I would just ensure that you keep your answer focused whilst showing depth, rather than trying to cover a wide range of considerations.
I hope that helps!
