I heard that quant finance companies target high-achievers by creating a sense of continuing tracks: recruiting based on high GPAs, an application process with a high-profile entrance exam, and so on. It creates an impression among their target group that such a company is where they "should" go to work, because it's at the top.
The weird thing with quant finance is that it basically started as a bunch of misfits from other disciplines. Mostly sub departments at banks and some funds no one ever heard of.
Now its a well trodden career path with specialized degree programs targeting it, online forums full of 16 year old aspirational hardos discussing which college to apply to in order to get into job 1 which leads to job 2 which leads to.. So again, train tracks.
Old quants are an interesting bunch to talk to. Guys who worked in plasma physics or are serious musicians or classically trained philosophy backgrounds, etc.
Now every grad resume I see for job openings looks exactly the same.
I no longer deal with grad/intern programs thankfully.
Agree in spirit though Iām a bit doubtful of your details (exams or GPAs, etc). I think part of this is presenting the work as looking more like university and less like what students might imagine work to look like.
