Trading Interview Case Studies

I'm through to the final round for a trading company/liquidity provider which is going to be a case study, I was wondering if anyone had any advice or could point me to resources to help prepare.

They've given me a list of things to look into, which I have been, and I've found a few posts on here and on Glassdoor about it, but I'm not finding a whole lot of specific info or examples of similar interviews for any companies.

It's easy enough to read someone saying "get good at hedging/arbitrage questions" or giving basic examples like "Security A trades at 1.5 times the underlying, Security B at 2 times. You're long 40000 in A, how would you hedge this with B" (the one specific example I've seen). What I can't seem to find is specific examples of full case studies or even individual similar questions so that I can practice.

I'm still getting into more of the theory that's been recommended but obviously it's a pretty broad area and I find its a lot easier to get to grips with the theory when you can start putting it into practice at some level.

Any insight or any ideas where I could get some more ideas would be appreciated, thanks.
