Looking for help

Hey guys,

I'm not sure if I'm posting this in the right sub-forum, I'm new here so please bear with me.
I just registered here today since I have an interview scheduled for next Wednesday at one of the largest banks in my country (the Netherlands) for an internship position (Corp/Institutional Banking). It's not a case-interview or something similar but more like an "informal" interview about my ambitions, background, and so on.

In order to prepare a bit, I've been looking online for useful guides (currently reading though the Vault guide on IB). Was wondering if you guys know about any useful websites, platforms, guides, communities, that offer valuable information about all sorts of Finance and related topics. I'm a last year's student in BSc International Business Administration so my knowledge on Finance is not too bad, yet I feel like I need to catch up on a lot of stuff.

Would be awesome if you guys can help me out a bit :)

Thanks,
Chaes
