Susquehanna International Group Buy-Side Research Process

I've poked around this forum and have found very little related to the buy-side research role at SIG. It appears to be a blend of traditional ER and some more quantitative techniques as well as the strategies are meant to be short term, and related to their options market making.

Does anyone have any insights on what the interview process is like compared to ER? I've passed the Capital Markets test, and have a first round interview soon. I know there will be probability/brainteaser related questions, but am curious how the fundamentals side of things will be incorporated. 

Thanks in advance.
