To be honest, the internship placement statistics mean literally nothing, considering the brief amount of training you receive before your application and the significant variance in candidate background even within the same program.
You start applying for internships even before coming to the program, and you start the majority of your OA and even some interviews before your midterm when you basically learned nothing more than where your dining hall is. We are all statisticians here, and as a statistician you probably should be aware that the high correlation between buy-side jobs and "good programs" does not necessarily imply causation. Let's be bluntly honest, smart kids get to good programs, and smart kids get to buy-side big names, but being surrounded by smart kids alone does not automatically make you a smart kid ---- and if you aint a smart kid (and if you do not have a gold medal dangling around your neck or if you are not sure whether you are smart then chances are you probably are not smart at a JaneStreet level), do not even dream of even reaching to the super day of JS/Citadel/Optiver/IMC/DEShaw/2Sig simply because you happen to be in a "Top 5 Quant Program as per QuantNet" together with some of those smart kids as your "PEERS" (who do not even bother to come to the lectures so technically "Peers" is an overstatement)
As a statistician, another harsh truth I have learned from my brief career is that the mean is more often than not misleading, especially when subgroups exist within the sample group. There is a bunch of Tsinghua guys/girls in Columbia MFE who know literally everything and came here just for the VISA (as per my great friend W.B.), and the fact that they got offer from JaneStreet/IMC/GS has nothing to do with an ordinary kid like me still struggling to ace my finals in 2 days. For all those innocent incoming applicants Window-shopping through QN going through the StatSheet back and forth time and time again daydreaming of models and bottles at a top HF/PropShop in NY/Chic/Bos/Lon/Amsterdam (trust me I'm in your shoes 2 years ago I know exactly the juice from daydreaming), I can guarantee y'all this: the average Columbia MFE ppl are struggling miserably, MISERABLY, as per my first-hand observation. I can also guarantee you guys that in the end, "WE" still gonna get good stats thanks to those TsingHua guys/girls, but what is the point? Brag about you got some Optiver "Network" from your Master program whom you have never ever seen for even one single peek since your DAY 1 Orientation?
An Optiver guy/girl will probably end up in Optiver no matter whether he/she is from Columbia, Berkeley, MIT, or CMU. If you aint an Optiver guy/girl, the most probable case is that neither Columbia nor CMU will provide you sufficient training in 1 month to land you in Optiver for an Internship.
I know, reality hurts.
