Hi there,
First of all, congratulations on the (presumed) invitation from Bain!
I would be happy to share my thoughts on your question:
- First of all, you can use all kinds of tools and applications as long as Bain allows it.
- Moreover, however, there does not seem to be a built-in calculator application.
You can find more on this topic here: How to succeed in the final interview round.
If you would like a more detailed discussion on how to best prepare for your upcoming Bain Sova pre-interview assessment and Bain interviews, please don't hesitate to contact me directly.
Best,
Hagen
