Questions from Incoming Undergrad about Recruiting

Hey everyone, I'm new to WSO so sorry if I break some norms. I'm an incoming undergraduate studying CS and math at UMich this fall. Now, I know that's not Princeton/MIT that everyone on this site seems to be choosing between, but I was wondering what tips you have for me early on.. In high school, I did some competitive math but honestly I never made it past AIME. Regardless, I've made a list of different coding/math/quant practice resources, and have started studying a probability textbook.

I know roles at top MMHF are spectacularly difficult, so I'm also wondering what types of disadvantages I'll be working with going to a school that, as far as I know, isn't a top target. Even compared to Berkeley, Cornell, Columbia etc. (schools I'm sadly waitlisted at), would you say there is going to be a pronounced difference with regards to getting interviews and getting past them? I've connected with a number of different UMich students/alumni who have been able to secure internships/jobs at firms like Citadel, JS, Optiver, etc. so I know it's possible, but if so, why does the sentiment seem to be HYPSM or bust? Is it the school, or is it just more likely a student at the caliber of a top quant firm would attend Harvard? Would appreciate any help in correcting/confirming what I've gathered, or any advice in general. Thanks.
