| I posted this. I'm just a regular dev, without any kind of attachment to Jane Street, in fact i'm a little wary of them, and would subscribe to Evan Czaplicki's understanding of the faustian bargain working there would involve. I think they're banned from India, if you want an example of the kind of raiding they are equipped to do. In general - I am wondering how engineering interviews change in the age of LLMs, Jane Street, tech-wise is a "thought leader", at least having opinions, sharing them is part of how they recruit "the best", i think oxide does this too. So in some way, in this time of change it makes sense that they are noisy... It also makes sense that the noises they make may filter down... |

Mind going more into this, since you named a specific person? Did he make some prominent statement? |

They make money in a way that's extremely unfair to the point a whole new stock exchange (IEX) was designed to stop it, hurts both retail and institutional investors, and provides no useful service to society. All they've ever done for anyone but themselves is work on the OCaml ecosystem which is not exactly the biggest or most innovative. | | |
| ▲ | kevstev 4 hours ago | parent | next [-] | | Man, HN has really started to decline. How exactly is Jane Street front running? Reacting faster than others to markets is not front running. Seeing someone else's order and putting yours in front of it is front running. Traders on the NYSE Floor would hear a big order is coming in, and put their ticket in front of it- that is front running. In a computerized world, front running has essentially ceased to exist- the last major enforcement actions I could find are from 2003, when there was still quite a bit of trading done not by pushing buttons on a computer but by making phone calls. Trading on inside information is alive and well, but this is not what JS does at all, that's the realm of hedge funds that have traders that still click on buttons. I never worked at JS, but have worked in MM. | | | |

They put on trades and take on risk in addition to having a market-making business. They're not the reason IEX was formed. Maybe they were a factor but idk. | |

| Yeah, sorry, I didn't mean to imply anything nefarious on your part (or anyone else's part). It's just odd that a single financial firm keeps coming up. |

| ▲ | Avicebron 4 hours ago | parent [-] | | OCaml like a lot of niche functional programming languages has a lot of weight on HN. Or used to for many many years, mostly before LLMs. Jane street is single-handedly keeping OCaml alive and in use in real applications and as such they get a lot of credence. Whether you agree with what they do or not, they have had a sort of mystique about them (tons of money, quant vests, _and_ a niche functional programming language as a daily driver??? Sign me up!) that HN likes. |
