I applied through college or university. I interviewed at Jane Street (New York, NY) in Nov 2024
Interview
A few 30-45 min technical phone interviews followed by an onsite super day. Technical questions were difficult but interesting, overall positive experience. Technical questions don’t require too much background knowledge but definitely a lot of practice.

Question 1
What is the expected value and optimal strategy of a game where you have 3 blue balls and 2 red balls in a bag, you get +$1 when you draw blue and -$1 when you draw red.
4 rounds before superday. didnt make it to superday. first round was basic prob and stats questions. r2-4 is all hard game theory style questions. no behavioral at all.
i heard superday is a combination of data analysis and more games
3 online interviews before the final on-site one. The whole process is around a month. Mostly consists of probability questions. Poker chips are given in the final round to bet on certain decisions.

Question 1
Figuring out the strategy of a computer opponent in a turn based game and devising a strategy against them.
zuerst basic fragen zum einsteigen danach ziemlich schnell weiter mit theoretischen fragen. anfangend mit einer eher leichten frage und langsam drauf aufbauend mit neuen Bedingungen. insgesamt war es meiner meinung nach eine gute Erfahrung.
