Did anyone hear from Jane Street? What does their interview process look like?

Depends on the role. They’re not exactly a small company. Usually 4-5 rounds of increasing difficulty for the quant roles. Lots of probability, usually starting with brainteasers. It’s tough but not anything deep. It sounds like a good place for more academic types.

I don’t know why any PhD would go for these jobs. There was a thread recently where a “top 2l phD admitted some undergrad colleagues are much better than him at the job. A smart Olympiad-ish level high schooler can clear their interview, I’m not sure why they don’t try to hire at that level.
If you like thinking hard about deeper problems, try macro HFs or explicitly researchy places like two sigma(they sponsor ML conferences and explicitly seek out hire fresh PhDs)

Just did my interview today. They asked a lot of probability questions. They were not difficult but I was a bit nervous and wanted to rush for the answers, my mind was blocked.
Anyway, I did not do well. I expect to not have the second round interview.How do they expect the answer, do they let you use paper to write relations etc? Or are these just questions on definitions?

Anyway, I did not do well. I expect to not have the second round interview.I'd be interested to hear some examples

You flipped a coin 10 times in a row and it came up heads each time. What is probability it comes up heads the 11th time.

great firm, but not an ideal fit for phd as mentioned earlier. they like smart ugrads with IMO experience.
The reason is that they get all the PhD lemons applying, who have more acquired knowledge but not necessarily more raw intelligence.
That’s the point, Einstein. There are multiple dimensions here, “smarts”, intellectual maturity, taste, time duration of typical projects/tasks, risk exposure etc
Jane St is like athletics, I’d imagine PhDs would be happier playing soccer or dancing ballet
