Morgan Stanley Quantitative Finance Summer Analyst Superday

I was selected for a Quant Finance superday at Morgan Stanley next week. I have also been interviewing with some prop trading firms, and I was wondering if the questions would be more along those lines (brainteasers, mental math, etc.) or more traditional banking stuff (market trends or whatever). For reference, I am a junior rn, so the application process up til now was just a series of phone interviews, rather than the big test I've seen others talk about online. In my phone interviews, I was pretty much exclusively asked CS/data science questions, but I would guess that a superday would cover a broader set of subjects. I'm hoping they keep the banking/econ questions to a minimum, because my background is more in stats. I was hoping to learn the finance stuff on the job lol
