hey Sandrou, completed mine today actually!
I agree with Helena in that it's tougher than most but there are things to prepare for/keep in mind when going into it.
So for the scenario interview you will need to have some general commercial knowledge. How a business works, how banks lend money, all the basic financial terms you hear thrown about. I prepared for this by reading Christopher Stoakes'
Commercial Awareness and signing up for one of Jaysen's commercial classes, specifically the M&A one. While m&a didn't come up, banks and loans did. I recommend signing up to his possible upcoming class on debt and equity if this stuff is confusing. Personally, I didn't find knowing their sectors well a requirement but maybe that's because I got a partner in banking and not something niche like energy.
For the case study, a good presentation structure and a really close attention to detail is important. What I mean by the latter is, read the contract details as closely as possible because they put things in to trip you up and see if you notice.
Do you have one coming up? Good luck to your friend and to you too
